Perspective on plasma membrane cholesterol efflux and spermatozoal function
Dhastagir Sultan Sheriff, Elshaari Farag Ali
May-August 2010, 3(2):68-75
DOI:10.4103/0974-1208.69337  PMID:21209749
The process of sperm maturation, capacitation, and fertilization occur in different molecular milieu provided by epididymis and female reproductive tract including oviduct. The different tissue environment with different oxygen tension and temperature may still influence the process of sperm maturation and capacitation. Reactive oxygen species (ROS) is reported to be an initial switch that may activate the molecular process of capacitation. Therefore, the generation of reactive oxygen species and its possible physiological role depends upon a balance between its formation and degradation in an open environment provided by female reproductive tract. The sensitivity of the spermatozoa to the action of ROS may be due to its exposure for the first time to an oxygen rich external milieu compared to its internal milieu in the male reproductive tract. Reduced temperature in testicular environment coupled with reduced oxygen tension may be the right molecular environment for the process of spermatogenesis and spermiogenesis. The morphologically mature spermatozoa then may attain its motility in an environment provided by the caput epididymis wherein, the dyenin motor can become active. This ability to move forward will make the spermatozoa physiologically fit to undertake its sojourn in the competitive race of fertilization in a new oxygen rich female reproductive tract. The first encounter may be oxygen trigger or preconditioning of the spermatozoa with reactive oxygen species that may alter the spermatozoal function. Infertility is still one of the major global health problems that need medical attention. Apart from the development of artificial methods of reproduction and development of newer techniques in the field of andrology focuses attention on spermatozoal structure and metabolism. Therefore, understanding the molecular mechanisms involved in fertilization in general and that of sperm capacitation in particular may help lead to new and better techniques for enhancing fertility, identifying and treating certain forms of male infertility, and preventing conception. One remarkable insight is the importance of membrane cholesterol efflux in initiating transmembrane signaling events that confer fertilization competence. The identity of the physiologically relevant cholesterol acceptors and modulators of cholesterol efflux is therefore of great interest. Still, it is clear that cholesterol efflux represents only a part of this story. The involvement of phospholipid translocation in mediating dynamic changes in the membrane, rendering it conducive to transmembrane signaling, and the modulation of membrane components of signal transduction cascades by cholesterol or phospholipids will yield important insights into the links between environmental sensing and transmembrane signaling in the sperm. Understanding the membrane molecular events will ultimately provide new and exciting areas of investigation for the future.

Predictive value of endometrial thickness, pattern and sub-endometrial blood flows on the day of hCG by 2D doppler in in-vitro fertilization cycles: A prospective clinical study from a tertiary care unit
Neeta Singh, Anupama Bahadur, Suneeta Mittal, Neena Malhotra, Ashok Bhatt
January-April 2011, 4(1):29-33
DOI:10.4103/0974-1208.82357  PMID:21772737
Aims and Objectives : To evaluate the role of endometrial thickness, pattern and sub-endometrial blood flows measured by 2D power Doppler ultrasound to predict pregnancy during in-vitro fertilization (IVF) treatment. Study Design : Prospective, non-randomized clinical study. Materials and Methods : This was a prospective observational study. A total of 101 infertile women were recruited from our IVF-ET program from January to December, 2009. Women with tubal factor, male factor and unexplained infertility were included in the study. Results : The mean age was 35 years and mean duration of infertility was 8 years. Seventy five (74.25%) patients had primary infertility and 26 (25.74%) had secondary infertility. The mean endometrial thickness was 8.1 mm and endometrial blood flow was in Zone I in 18 patients, 28 patients had blood flow in Zone II and 54 had in Zone III. Overall, 27 (26.73%) patients conceived and in these women the endometrial thickness was between 6 and 12 mm. Conclusions : With a thin endometrium (≤7 mm) and no-triple-line endometrial pattern coexisting in an in-vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) candidate, cryopreservation should be recommended. With a thin endometrium and a good texture (triple-line), other prognostic factors, such as embryo quality, should be taken into account. The endometrial vascularity has a useful predictive value on the implantation rate in IVF cycles irrespective of the morphological appearance of the endometrium. However, further study is needed to make a definitive conclusion.

"Mixed germ cell testicular tumor" in an adult female
Udasimath Shivakumarswamy, R Purushotham, HK Kumar Naik, KR Nagesha
January-April 2012, 5(1):64-66
DOI:10.4103/0974-1208.97810  PMID:22870019
The androgen insensitivity (testicular feminization) syndrome was described by Morris in phenotypic females with 46XY karyotype, presenting with primary amenorrhea, adequate breast development, and absent or scanty pubic or axillary hair. Gonads consist usually of seminiferous tubules without spermatogenesis. These patients have a 5-10% risk of developing germ cell tumors, usually after the complete development of secondary female sexual characteristics. We hereby report a case considered as a female with married life of 15 years, who was operated for severe abdominal pain. Phenotype characters were that of female. Microscopic examination of the tumor from the abdomen revealed germinoma and yolk sac tumor with adjacent seminiferous tubules. Karyotyping showed 46XY. Final diagnosis of malignant mixed germ cell tumor in androgen insensitivity syndrome was made. Surveillance may be the most appropriate option when these conditions are initially diagnosed in adulthood to prevent development of germ cell tumors.

Sample size estimation and power analysis for clinical research studies
KP Suresh, S Chandrashekara
January-April 2012, 5(1):7-13
DOI:10.4103/0974-1208.97779  PMID:22870008
Determining the optimal sample size for a study assures an adequate power to detect statistical significance. Hence, it is a critical step in the design of a planned research protocol. Using too many participants in a study is expensive and exposes more number of subjects to procedure. Similarly, if study is underpowered, it will be statistically inconclusive and may make the whole protocol a failure. This paper covers the essentials in calculating power and sample size for a variety of applied study designs. Sample size computation for single group mean, survey type of studies, 2 group studies based on means and proportions or rates, correlation studies and for case-control for assessing the categorical outcome are presented in detail.

An overview of randomization techniques: An unbiased assessment of outcome in clinical research
KP Suresh
January-April 2011, 4(1):8-11
DOI:10.4103/0974-1208.82352  PMID:21772732
Randomization as a method of experimental control has been extensively used in human clinical trials and other biological experiments. It prevents the selection bias and insures against the accidental bias. It produces the comparable groups and eliminates the source of bias in treatment assignments. Finally, it permits the use of probability theory to express the likelihood of chance as a source for the difference of end outcome. This paper discusses the different methods of randomization and use of online statistical computing web programming (www.graphpad.com/quickcalcs or www.randomization.com) to generate the randomization schedule. Issues related to randomization are also discussed in this paper.

The impact of female obesity on the outcome of fertility treatment
Shilpi Pandey, Suruchi Pandey, Abha Maheshwari, Siladitya Bhattacharya
May-August 2010, 3(2):62-67
DOI:10.4103/0974-1208.69332  PMID:21209748
The rising prevalence of obesity has had a profound impact on female reproductive health. Increased body mass index (BMI) is associated with ovulatory subfertility and anovulatory infertility. Overweight and obese women have poorer outcomes following fertility treatment. They respond poorly to clomiphene induction of ovulation and require higher doses of gonadotrophins for ovulation induction and superovulation. Ovarian stimulation for assisted reproduction produces fewer follicles resulting in the harvest of fewer oocytes. Fertilization rates are poorer and the embryo quality is impaired in younger women who are obese. Pregnancy rate in some studies is lower and there is an increased risk of early pregnancy loss. Weight loss regularizes menstrual cycles and increases the chance of spontaneous ovulation and conception in anovulatory overweight and obese women. Gradual sustained weight loss is beneficial whereas crash dieting is detrimental.

OHVIRA: Uterus didelphys, blind hemivagina and ipsilateral renal agenesis: Advantage MRI
Sunil K Bajaj, Ritu Misra, Brij B Thukral, Rohini Gupta
January-April 2012, 5(1):67-70
DOI:10.4103/0974-1208.97811  PMID:22870020
We present here a case of an uncommon complex uterine anomaly - Obstructed HemiVagina with Ipsilateral Renal Agenesis (OHVIRA), also known as Herlyn-Werner-Wunderlich syndrome in a 14-year-old girl along with sonographic (trans-abdominal and trans labial), and MRI findings. The patient underwent surgery wherein imaging findings were confirmed. An MRI has proved to be of great help in correct diagnosis avoiding surgical interventions/ laparoscopy, which were needed in past to diagnose this rare anomaly. We also discuss the development of this anomaly with the help of a relatively new theory of uro-genital development by Acien and review the literature.

Does local endometrial injury in the nontransfer cycle improve the IVF-ET outcome in the subsequent cycle in patients with previous unsuccessful IVF? A randomized controlled pilot study
Sachin A Narvekar, Neelima Gupta, Nivedita Shetty, Anu Kottur, MS Srinivas, Kamini A Rao
January-April 2010, 3(1):15-19
DOI:10.4103/0974-1208.63116  PMID:20607003
Background: Management of repeated implantation failure despite transfer of good-quality embryos still remains a dilemma for ART specialists. Scrapping of endometrium in the nontransfer cycle has been shown to improve the pregnancy rate in the subsequent IVF/ET cycle in recent studies. Aim: The objective of this randomized controlled trial (RCT) was to determine whether endometrial injury caused by Pipelle sampling in the nontransfer cycle could improve the probability of pregnancy in the subsequent IVF cycle in patients who had previous failed IVF outcome. Setting: Tertiary assisted conception center. Design: Randomized controlled study. Materials and Methods: 100 eligible patients with previous failed IVF despite transfer of good-quality embryos were randomly allocated to the intervention group and control groups. In the intervention group, Pipelle endometrial sampling was done twice: One in the follicular phase and again in the luteal phase in the cycle preceding the embryo transfer cycle. Outcome Measure: The primary outcome measure was live birth rate. The secondary outcome measures were implantation and clinical pregnancy rates. Results: The live birth rate was significantly higher in the intervention group compared to control group (22.4% and 9.8% P = 0.04). The clinical pregnancy rate in the intervention group was 32.7%, while that in the control group was 13.7%, which was also statistically significant ( P = 0.01). The implantation rate was significantly higher in the intervention group as compared to controls (13.07% vs 7.1% P = 0.04). Conclusions: Endometrial injury in nontransfer cycle improves the live birth rate,clinical pregnancy and implantation rates in the subsequent IVF-ET cycle in patients with previous unsuccessful IVF cycles.

DMAB Dissanayake, PS Wijesinghe, WD Ratnasooriya, S Wimalasena
July-December 2009, 2(2):57-61
DOI:10.4103/0974-1208.57223  PMID:19881149
Context: Effects of zinc on male sexual competence are poorly understood. Aim: To study the effects of different doses of zinc on the sexual competence of males using a rat model. Materials and Methods: Three subsets (eight in each subset) of sexually experienced adult male rats were supplemented with three different oral doses of zinc sulphate (a daily dose of 1 mg, 5 mg and 10 mg respectively) for two weeks. A subset of eight animals without zinc supplementation was used as the control group Sexual behavior was observed by placing them individually in cages with receptive females. Statistical Analysis : Data analysis was done using SPSS v10 for windows computer software. Results: Supplementation of 5 mg of zinc/day for two weeks led to a prolongation of ejaculatory latency; 711.6 sec. (SEM 85.47) vs. 489.50 sec. (SEM 67.66), P< 0.05 and an increase in number of penile thrusting; 52.80 (SEM 11.28) vs. 26.50 (SEM 6.17), P< 0.05, compared to controls. The same group had elevated prolactin (PRL) and testosterone (T) levels compared to controls at the end of treatment period; PRL- 7.22 ng/dl (SEM 3.68) vs. 2.90 ng/dl (SEM 0.34) and T- 8.21 ng/ml (SEM 6.09) vs. 2.39 ng/ml (SEM 1.79), P< 0.05. In contrast, reduction of libido was evident in the same group, but this effect was not statistically significant ( P> 0.05). However, partner preference index was positive and 5 mg zinc supplementation did not exert a significant adverse effect on the muscle strength and co-ordination. The subset of rats supplemented with 1 mg/day did not show a difference from the control group while supplementation with 10 mg/day led to a reduction of the libido index, number of mounts and intromissions. Conclusions : Zinc therapy improves sexual competence of male rats; the effect is dose dependent. Increase in the T levels is beneficial in this regard. However, increase in PRL is responsible for the reduced libido index. Further studies on pigs and monkeys are needed to evaluate the therapeutic use of zinc in sexual dysfunction.

Imaging techniques for assessment of tubal status
Sonal Panchal, Chaitanya Nagori
January-March 2014, 7(1):2-12
DOI:10.4103/0974-1208.130797  PMID:24829524
Fallopian tubes make a vital portal for transfer of gametes and embryo. Tubal factor is responsible for infertility in 25-35% of cases. Hysterosalpingography (HSG) has been used to evaluate the uterine cavity and the tubal status since decades. It uses iodinated contrast and X-rays and is painful and inconvenient for patient. Laparoscopy is considered to be the gold standard for tubal evaluation, but is an operative procedure and needs anesthesia. Though ultrasound is a modality of choice for assessment of uterus and ovaries, it does not allow assessment of the fallopian tube unless there is any fluid surrounding it or inside the lumen. This fluid interface can be created artificially by introducing saline in the uterine cavity and fallopian tubes and scanning simultaneously. The procedure is named Saline infusion HSG. Saline infusion sonohysterosalpingography (SIS) can be done with B mode US and Doppler. SIS can demonstrate a patent tube but if blocked, the site of block cannot be demonstrated. Ultrasound contrast agents can be used for tubal assessment using contrast mode on the scanners. This procedure is known as hystero-contrast sonography (HyCoSy). This actually shows the passage of hyperechoic contrast agent through tubal lumen and delineates it and locates the site of block. Using the volume ultrasound may even make the demonstration of tubal status and fimbriae better. Results of HyCoSy have been found to correlate well with laparoscopic findings, which are a gold standard. It is recommended by National Institute for Health and Clinical Excellence as a primary investigation for tubal assessment in patients without any positive history of tubal damage and also can replace a second look laparoscopy.

A Baxi, M Kaushal
January-June 2008, 1(1):25-28
DOI:10.4103/0974-1208.39593  PMID:19562060
Context : There is a continuous controversy regarding the obstetric perinatal outcome of twin pregnancies conceived after assisted reproductive techniques (ART). There is an ongoing discussion whether theses parameters may show poorer results as compared to spontaneous conception. Aims: To evaluate the outcome of multifetal pregnancies and to compare maternal and neonatal complications between spontaneously conceived and assisted reproductive therapy. Settings and Design : Prospective case-control study. Materials and Methods :In this prospective case-control study of 2-year duration, obstetric and perinatal outcomes were compared in 36 ART twin pregnancies (Group A) with 138 twins who conceived naturally (Group B). The outcomes were analyzed and used for a comparison between spontaneous and assisted multifetal pregnancies. Statistical Analysis : The continuous variables were analyzed by Student's t -test and categorical variables were analyzed with Fisher's exact test. Results : Pregnancy-related complications like pregnancy-induced hypertension, antepartum hemorrhage, were similar in both groups. Incidence of cesarean section, preterm delivery, and hospital stay was significantly more in Group A vs. Group B, P < 0.001. The newborns in the assisted group had more complications than the spontaneous group; most notable were respiratory distress syndrome, newborn intensive care admission, sepsis, and longer hospital stay (4.8 days vs. 1.6 days, P < 0.001). Conclusions : Increased rates of cesarean section and preterm delivery are the main reasons for increased obstetric risk in pregnancies conceived through ART. Preterm birth and neonatal prematurity-related complications were the main cause for longer stay in hospital in ART-conceived twins.

The efficacy of metformin and clomiphene citrate combination compared with clomiphene citrate alone for ovulation induction in infertile patients with PCOS
Papa Dasari, GK Pranahita
January-June 2009, 2(1):18-22
DOI:10.4103/0974-1208.51337  PMID:19562069
Context: Low ovulatory and pregnancy rates with clomiphene citrate (CC) in anovulatory polycystic ovarian syndrome (PCOS). Aim: To find out the ovulatory and pregnancy rates in infertile PCOS subjects who receive CC alone and a combination of metformin and CC. Setting and Design: A prospective controlled clinical trial conducted in the outpatient department from August 2003 to August 2005. Materials and Methods: Twenty-four infertile PCOS women received CC alone at incremental doses of 50 mg up to 150 mg for three cycles and then at a dose of 150 mg for another three cycles (control group). The study group (16 PCOS) received the same dose of CC along with 1500mg of metformin. Ovulation was monitored by transvaginal sonography up to six cycles or till pregnancy occurred. Statistical Analysis: This was carried out using software SSPS, version 10. Fisher's exact test was used to calculate the ovulatory rates. Nine subjects of the control group who failed to conceive with CC had opted for CC and metformin and their ovulatory rate was calculated using statistical software, namely SPSS 15.0, Stata 8.0, MedCalc 9.0.1 and Systat 11.0 using Fischer's exact test. Results: The metformin and clomiphene combination resulted in a significantly higher rate of ovulation ( P = 0.0016). The pregnancy rate was 8% with CC and 24% with metformin and CC. The CC failure group also ovulated at a similar rate as that of the study group. Conclusions: The ovulatory rate and the pregnancy rate with the metformin-CC combination was found to be higher when compared with CC alone. Metformin increased the ovulatory rate in CC failures, also implying increased sensitivity to CC.

DOI:10.4103/0974-1208.39594  PMID:19562061
Objective : To study the efficacy of gonadotrophin releasing hormone (GnRH) antagonist in In-vitro-fertilization/Intracytoplasmic sperm injection (IVF/ICSI) cycles. Type of Study : Observational study. Setting: Reproductive Medicine Unit, Christian Medical College Hospital, Vellore, Tamil Nadu. Materials and Methods: GnRH antagonists were introduced into our practice in November 2005. Fifty-two women undergoing the antagonist protocol were studied and information gathered regarding patient profile, treatment parameters (total gonadotrophin dosage, duration of treatment, and oocyte yield), and outcomes in terms of embryological parameters (cleavage rates, implantation rates) and clinical pregnancy. These parameters were compared with 121 women undergoing the standard long protocol. The costs between the two groups were also compared. Main Outcome : Clinical pregnancy rate. Results : The clinical pregnancy rate per embryo transfer in the antagonist group was 31.7% which was comparable to the clinical pregnancy rate in women undergoing the standard long protocol (30.63%). The costs between the two groups were comparable. Conclusions : GnRH antagonist protocol was found to be effective and comparable to the standard long protocol regimen. In addition it was simple, convenient, and patient friendly.

Endometrial regeneration using autologous adult stem cells followed by conception by in vitro fertilization in a patient of severe Asherman's syndrome
Chaitanya B Nagori, Sonal Y Panchal, Himanshu Patel
January-April 2011, 4(1):43-48
DOI:10.4103/0974-1208.82360  PMID:21772740
In a woman with severe Asherman's syndrome, curettage followed by placement of intrauterine contraceptive device (IUCD) (IUCD with cyclical hormonal therapy) was tried for 6 months, for development of the endometrium. When this failed, autologous stem cells were tried as an alternative therapy. From adult autologous stem cells isolated from patient's own bone marrow, endometrial angiogenic stem cells were separated using immunomagnetic isolation. These cells were placed in the endometrial cavity under ultrasound guidance after curettage. Patient was then given cyclical hormonal therapy. Endometrium was assessed intermittently on ultrasound. On development of endometrium with a thickness of 8 mm and good vascularity, in vitro fertilization and embryo transfer was done. This resulted in positive biochemical pregnancy followed by confirmation of gestational sac, yolk sac, and embryonic pole with cardiac activity on ultrasound. Endometrial angiogenic stem cells isolated from autologous adult stem cells could regenerate injured endometrium not responding to conventional treatment for Asherman's syndrome.

SK Adiga, V Jayaraman, G Kalthur, D Upadhya, P Kumar
January-June 2008, 1(1):15-18
DOI:10.4103/0974-1208.38972  PMID:19562058
Background : Male reproductive function has recently attracted increasing attention due to reports on time-related decline in semen quality. Furthermore, regional differences in the semen quality have also been reported. Aim : To investigate the semen quality among large cohort of infertile individuals at a regional level, in terms of the sperm concentration, total sperm motility, sperm morphology and incidence of azoospermia over a period of 13 years. Setting : University infertility clinic at Kasturba Hospital, Manipal which is a tertiary healthcare centre serving the general population. Design : Retrospective analysis. Materials and Methods: This includes a total of 7770 subjects who presented for semen analysis from 1993 to 2005. The data regarding ejaculate volume, sperm density, motility, morphology and the incidence of azoospermia were collected. Statistical Analysis Used : One way analysis of variance (ANOVA), regression analysis and Chi square analysis. Results : The average sperm density among infertile men during 2004-2005 was 26.61 0.71 millions/mL which was significantly lower than the average sperm density observed in 1993-1994 (38.18 1.46 millions/mL). Similar trend was also observed for sperm motility (47.14% motile sperms vs. 61.16%) and normal sperm morphology (19.75% vs. 40.51%). Interestingly, the incidence of severe oligospermia (mean sperm density <10 millions/mL) observed in 2002-2005 and 1993-1997 demonstrated a significant inverse relationship ( P < 0.001). Conclusion : Our study provides the first evidence that the quality of human semen evaluated for infertility is deteriorating in the southern part of the India over the years, probably due to environmental, nutritional, life style or socioeconomic causes.

Polycystic ovaries and infertility: Our experience
Lavanya Rajashekar, Deepika Krishna, Madhuri Patil
July-December 2008, 1(2):65-72
DOI:10.4103/0974-1208.44113  PMID:19562048
Background: Polycystic ovary syndrome (PCOS) is one of the most common (15-20%) endocrine disorders in women of childbearing age. Although it is a major cause of infertility, its etiology remains unknown and its treatment difficult. Aim: To evaluate the incidence, treatment and outcome of patients with PCOS. DESIGN: Retrospective analysis. Materials and Methods: PCOS patients (914 of the 1057) attending the outpatient department (OPD) from June 2003 to February 2008 were evaluated for this study. Of the 914 patients investigated, 814 came for treatment and these patients were studied for hormonal disturbances and their response to various modalities of treatment. Results: Of the 2270 infertility patients, 46.50% (1057) had PCOS, out of these, 86.47% (914) were investigated and 77% (814) came for treatment. Our overall pregnancy rate was 48.40% (394/814). The pregnancy rate per cycle with timed intercourse (TI) was 44.77% (47/105), 17.09% (286/1673) with intrauterine insemination (IUI), 29.82% (51/171) with in vitro fertilization (IVF) and 22.22% (10/45) with frozen embryo transfer (FET). The maximum number of pregnancies (85.29%, 284/333) were achieved in the first three treatment cycles. The abortion rate was 19.01% (73/384) and the incidence of ectopic pregnancy was 5.47% (21/384). Complications seen were in the form of ovarian hyperstimulation (OHSS), retention cyst on day two and multiple pregnancies in 11.71% (228/1946) of the total treatment cycles. Conclusion: Most PCOS symptoms could be adequately controlled or eliminated with proper diagnosis and treatment. Thus, ovulation induction (OI) protocols and treatment modalities must be balanced for optimal results.

Ovarian torsion in infertility management - Missing the diagnosis means losing the ovary: A high price to pay
Sandhya Krishnan, Harpreet Kaur, Jyoti Bali, Kamini Rao
January-April 2011, 4(1):39-42
DOI:10.4103/0974-1208.82359  PMID:21772739
Ovarian torsion is a rare entity and the diagnosis is commonly missed. Here we present a series of two cases of ovarian torsion. First case followed the in vitro fertilization treatment, along with ovarian hyperstimulation syndrome, where even with timely intervention and laparoscopy, we had to compromise one ovary. Second case followed the ovulation induction and intrauterine insemination - where timely intervention helped us to save the ovary.

Successful pregnancy following medical management of heterotopic pregnancy
R Lavanya, K Deepika, Madhuri Patil
January-June 2009, 2(1):35-40
DOI:10.4103/0974-1208.51350  PMID:19562073
We present a case of sonographic demonstration of quadruplet heterotopic pregnancy consisting of twin intrauterine (IU) pregnancy and a twin adnexal pregnancy after ovulation induction (OI) with clomiphene citrate (CC) and timed intercourse (TI). Both heterotopic pregnancy and spontaneous twinning are frequent after OI, this combination although extremely rare must be kept in mind. The role of early transvaginal sonography and serum beta human chorionic gonadotrophin after missed periods helps in early diagnosis. It gives us an opportunity for medical management, saving the patient the agony of surgery along with loss of pregnancy. The management of heterotopic pregnancy is controversial. This patient did not have a viable IU pregnancy and both the sacs in the adnexa were small. Thus, we treated her successfully by medical management with systemic methotrexate, with regular follow-up. This patient successfully conceived after 6 months with OI and TI, with ovulation occurring from the same side of the previous ectopic. She had a viable IU gestation corresponding to 12 weeks.

Complete imperforate tranverse vaginal septum with septate uterus: A rare anomaly
Nutan Jain, Anjali Gupta, Ravindra Kumar, Agnes Minj
January-March 2013, 6(1):74-76
DOI:10.4103/0974-1208.112387  PMID:23869157
The isolated, complete, transverse vaginal septum is one of the most infrequent anomalies of the female genital tract, and when it coexists with a septate uterus, it is even rarer. This report describes a case of transverse vaginal septum with septate uterus. A 12-year-old girl sought medical assessment because of severe cyclic lower abdominal cramping and pelvic pain. Local examination revealed a blind vaginal pouch of 2 cm and on rectal examination a tender pelvic mass was noted. Radiological examination showed transverse vaginal septum in the lower vagina with bicornuate uterus. Surgical resection of the vaginal septum was done under laparoscopic guidance. Hysteroscopy revealed presence of uterine septum which was resected by a resectoscope. Post-operative dilatation of vagina was done to prevent restenosis. Laparoscopic guided abdominoperineal approach is better in such a case as multiple mullerian anomalies may coexist with each other.

Ann M Mangalraj, K Muthukumar, TK Aleyamma, Mohan S Kamath, Korula George
January-June 2009, 2(1):23-26
DOI:10.4103/0974-1208.51339  PMID:19562070
Objective: To evaluate the efficacy of blastocyst transfer in comparison with cleavage stage embryo in a similar cohort of women. Design: Retrospective analysis. Setting: University teaching hospital. Materials and Methods: Women aged 35 or less undergoing in vitro fertilization/intracytoplasmic sperm injection between January 2005 and December 2006 were included in the study. When four or more grade 1 embryos were observed on day 3, extended culture till day 5 was undertaken. This policy was compared with a cohort of women who had at least three grade 1 embryos on day 3 and who had undergone a cleavage stage embryo transfer during the time period of January 2002-December 2004. Primary outcome evaluated was implantation rate and clinical pregnancy rate. Results: Group 1 consisted of 50 women who underwent extended culture and blastocyst transfer. Group 2 comprised of 85 women who had cleavage transfer. The implantation rate for embryos transferred in group 1 was significantly higher than that for embryos transferred on day 3 (40.16% vs 11.43%). The clinical pregnancy rate was also significantly better with blastocyst transfer as compared with cleavage stage transfer (62% vs 29.76%). Significantly fewer embryos were required for transfer at the blastocyst stage compared with day 3 transfer (2.54 vs 3.45). Conclusion: In selected cases, blastocyst transfer with fewer embryos can be performed with high implantation and clinical pregnancy rates. This policy could lead to a reduction in the incidence of higher-order pregnancies.

Effect of forced swimming stress on count, motility and fertilization capacity of the sperm in adult rats
Ghasem Saki, Fakher Rahim, Karim Alizadeh
July-December 2009, 2(2):72-75
DOI:10.4103/0974-1208.57226  PMID:19881152
Aims: The purpose of this study was to determine whether 50 days of forced swimming stress applied to adult male rats affects count, motility and fertilization capacity of sperm. Settings and Design: It is a prospective study designed in vitro. Materials and Methods: A total 30 adult male wistar rats were used in this study. All rats were divided into two equal groups (n = 15): (1) control group and (2) experimental group. Animals of the experimental group were submitted to force swimming stress for 3 min in water at 32°C daily for 50 days. Then, all male rats were sacrificed, the right epididymides were removed and sperm concentration and motility were determined. The sperm suspension was added to the ova. Fertilization capacity was assessed by counting two-cell embryos 24-26 h after completion of fertilization in vitro. Statistical Analysis Used: Data are reported as mean ± SD and percentage. The difference between the control and experimental groups was determined by the unpaired t-test. Results: The mean and standard deviation of sperm concentration in the control and experimental groups were 60.8 ± 9.3 10 6 /ml and 20.4 ± 5.3 10 6 /ml, respectively. There was a statistical difference of P < 0.05 between the two groups in terms of sperm concentration. The percentage of motility in the experimental group was significantly different ( P < 0.05). The same results were obtained in case of fertility ( P < 0.05). Stress caused by forced swimming was observed by a significant increase in the latency of the pain response in the hot-plate test ( P < 0.05). Conclusions: These results suggest that forced swimming stress in time course equal or more than spermatogenesis period, i.e. 48-50 days in the rat will be significantly effective to reduce the number and motility of sperms as well as the fertilization capacity.

Assessing tubal damage
Madhuri Patil
January-June 2009, 2(1):2-11
DOI:10.4103/0974-1208.51335  PMID:19562067
The fallopian tube plays an important role in the mechanical transport and physiological sustenance of the gametes and early conceptus. Complex and coordinated neuromuscular activity, cilial action and endocrine secretions are required for successful tubal function. Compromised tubal damage can occur after external or internal injury, inhibiting the normal transport of gametes. The overall prognosis for fertility depends principally on the insult and the severity of the tissue damage; hence, assessment of tubal damage plays a major role in predicting occurrence of pregnancy and the likelihood of developing ectopic pregnancy.

Screening of 'Y' chromosome microdeletions in Iranian infertile males
Ali Mohammad Malekasgar, Hayat Mombaini
January-June 2008, 1(1):2-9
DOI:10.4103/0974-1208.38973  PMID:19562056
Background : It has been hypothesized that microdeletions of Yq may account for a significant proportion of men with infertility. Three nonoverlapping regions, referred to as "azoospermia factors" (AZFa, b, c from proximal to distal Yq) have been defined as spermatogenesis loci and deletions in these regions have been shown to be pathogenically involved in male infertility associated with azoospermia or severe oligospermia. Aims: Evaluation the frequency of Y chromosome microdeletions in Iranian population. Materials and Methods: Fifty infertile men were selected. Semen analysis was done and on the basis of the mean sperm count, all patients were categorized into azoospermia and oligozoospermia, groups. Blood samples were obtained for DNA extraction and chromosomal analysis. Genomic DNA was extracted from blood lymphocytes and amplified by sequence tagged sites-polymerase chain reaction (STS-PCR) method to determine the presence of microdeletions in AZF locus. A total of 34 STS primers including two controls were selected to identify microdeletions of Y chromosome on each subject. Results and Conclusion: 26/50 cases (52%) showed deletion of at least one of the STS Marker. Totally 41 microdeletions was observed. A total of 17 cases (34%) had deletion in one STS. Four oligospermia cases (8%) had deletion in 2 STS site. Three azoospermia cases (6%) had again deletion in 2 STS site, but in different STSs. One case had three deletions in three STS site and finally one individual had seven deletions in AZF locus. The overall frequency of Y chromosome microdeletions observed in the present study was found to be 26/50 (52%). Comparison of our data with the result of other investigators world wide shows that the incidence of Yq microdeletions in Iranian population is much higher than international frequency. Our data agree with other studies regarding microdeletions of AZFc, but for microdeletions of AZFa (14.6%) our results is much higher and differ significantly with many studies.
