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.

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.

Effect of bromocriptine on the severity of ovarian hyperstimulation syndrome and outcome in high responders undergoing assisted reproduction
Vinita Sherwal, Sonia Malik, Vandana Bhatia
May-August 2010, 3(2):85-90
DOI:10.4103/0974-1208.69342  PMID:21209752
Context: Ever since ovarian hyperstimulation syndrome (OHSS) was recognized as a clinical entity, various treatment modalities have been tried to prevent its occurrence and reduce its severity. Many recent studies have evaluated the role of dopamine agonists in reducing the incidence of OHSS. Objectives: To assess the effectiveness of dopamine agonist bromocriptine in reducing the incidence and severity of OHSS in patients undergoing assisted reproduction and its effect on pregnancy rates. Settings and Design: It was a prospective study in which patients at high risk of developing OHSS undergoing assisted reproduction were recruited. Materials and Methods: The study was carried out from August 2008 to August 2009 in patients undergoing assisted reproduction and included 40 patients at high risk for developing OHSS. Tablet bromocriptine 2.5 mg was prescribed for a period of 16 days starting from day of ovum pick up. Patients were analyzed on the basis of incidence of moderate and severe OHSS, timing of onset of OHSS (early/late), hospitalization rate, pregnancy rates and tolerability of medication and were compared with a historical group of high responders matched for age and BMI. Statistical Analysis: Student's t test and proportion test were used. Results: There was a significant reduction in the incidence of moderate OHSS (P=0.037), early OHSS (P=0.012) as well as the number of admissions (P=0.030). Average duration of hospitalization was also significantly reduced (P=0.036). In the study group, the incidence of clinically significant OHSS was 17.5% as compared to 40.9% in the control group. No difference was detected between the groups in clinical pregnancy rates (P=0.0054). Conclusion: Bromocriptine reduced the incidence and severity of clinically significant OHSS in high risk patients without affecting the pregnancy rates.

Demographic characteristics and clinical profile of poor responders in IVF / ICSI: A comparative study
Nabaneeta Padhy, Shalu Gupta, Asmita Mahla, M Latha, Thangam Varma
May-August 2010, 3(2):91-94
DOI:10.4103/0974-1208.69343  PMID:21209753
Background: Ovarian response varies considerably among individuals and depends on various factors. Poor response in IVF yields lesser oocytes and is associated with poorer pregnancy perspective. Cycle cancellation due to poor response is frustrating for both clinician and the patient. Studies have shown that women conceiving after poor ovarian response have more pregnancy complications like PIH and preeclampsia than women with normal ovarian response. In addition, poor ovarian response could be a predictor of early menopause. This paper studies various demographic and clinical profiles of poor responders and tries to look at the known and unknown factors which could contribute to poor ovarian response in IVF. Materials and Methods: Data were collected retrospectively from 104 poor responders who had less than four oocytes at retrieval and compared with 324 good responders for factors like age, BMI, type of sub fertility, duration of sub fertility, environmental factors like stress at work, smoking, pelvic surgery, chronic medical disorder, indication of IVF, basal FSH, mean age of menopause in their mothers etc. Results: Among the poor responders, 60.57% were above 35 years of age compared to 36.41% in control group, which is statistically significant. Mean age of menopause in mother was found to be four years earlier in poor responder group. Male factor and unexplained infertility were significantly (P<0.05) higher in good responders (P<0.05). Significant proportion (31.73%) of women in study group had undergone some pelvic surgery (P<0.05). Conclusion: Apart from age, prior pelvic surgery also could be used as predictors for poor ovarian response. Heredity also plays a major role in determining ovarian response.

Hyperprolactinemia with normal serum prolactin: Its clinical significance
Manika Agarwal, Ananya Das, Santa A Singh
May-August 2010, 3(2):111-112
DOI:10.4103/0974-1208.69334  PMID:21209758
Amenorrhea and infertility with an added feature of galactorrhea makes a provisional diagnosis of hyperprolactinemia. But again, normal serum prolactin with all clinical features of hyperprolactinemia might question the diagnosis and further management. The answer lies in the heterogeneity of the peptide hormone - the immunoactive and the bioactive forms. This has been further illustrated with the help of a case which had been treated with cabergoline.

Endometrial osseous metaplasia: Clinicopathological study of a case and literature review
T Umashankar, Shobhana Patted, RS Handigund
May-August 2010, 3(2):102-104
DOI:10.4103/0974-1208.69329  PMID:21209755
Endometrial osseous metaplasia is an uncommon clinical entity with the presence of bone in the endometrium. Most of the cases clinically present with secondary infertility following an abortion. Various theories have been proposed and the most accepted theory is metaplasia of the stromal cells into osteoblastic cells that produce the bone. It is important to distinguish this condition from the mixed mullerian tumor of the endometrium to avoid hysterectomy. Removal of these bony bits leads to spontaneous conception. We present one such case in a 25-year-old female patient presented with secondary infertility.

A rare case of intact rudimentary horn pregnancy presenting as hemoperitoneum
Ruchi Jain, Neha Gami, Manju Puri, SS Trivedi
May-August 2010, 3(2):113-115
DOI:10.4103/0974-1208.69335  PMID:21209759
The availability of technological advances like ultrasonography (USG) and magnetic resonance imaging (MRI) has made the diagnosis of rudimentary horn pregnancy possible at an early gestation. However, in advanced pregnancy, such cases can sometimes pose a diagnostic dilemma and are recognized only when patient presents with abdominal pain and collapse and is taken for laparotomy. We report one such rare case of a nulliparous female who was carrying on well with her pregnancy till she developed symptoms of acute abdomen at 28 weeks of gestation. She underwent USG and MRI but it was only after laparotomy that a final diagnosis of a pregnancy in a rudimentary horn with placenta percreta perforating through the fundus could be made. There was a significant amount of hemoperitoneum; however, the horn was intact and the fetus could be salvaged. We excised the rudimentary horn with ipsilateral tube and ovary. Post operatively, both the mother and the baby were discharged in healthy condition.

Comparative evaluation of pregnancy outcome in gonadotrophin-clomiphene combination vs clomiphene alone in polycystic ovarian syndrome and unexplained infertility-A prospective clinical trial
Shiuli Mukherjee, Sunita Sharma, BN Chakravarty
May-August 2010, 3(2):80-84
DOI:10.4103/0974-1208.69341  PMID:21209751
Objectives: A large prospective clinical trial was conducted to compare the efficacy of single dose uFSH and clomiphene citrate combination with clomiphene citrate alone for ovulation induction to improve the pregnancy rate. Materials and Methods: The study was a randomized, prospective clinical trial. Totally, 1527 infertile women (4381 cycles) with polycystic ovarian syndrome (PCOS) (n=911/2573 cycles) and unexplained infertility (n=616/1808 cycles) were randomized into two groups. Group A received single dose of uFSH on D 3 of menstrual cycle along with clomiphene. Group B received clomiphene only for ovulation induction. We compared the pregnancy rate and miscarriage rate between two groups. Results: Group A had a pregnancy rate of 17% compared to 8.3% of Group B which was significantly higher (P=0.0001). The miscarriage rate was 11% in Group A and 10% in Group B which was not significant (P=0.99). Pregnancy rates in PCOS women were 22% in Group A and 9.3% in Group B which shows significantly higher pregnancy rate (P=0.0001) in anovulatory infertility. But in unexplained infertility, there was no significant difference in pregnancy rate between Group A (11%) and Group B(6.3%). Miscarriage rates were 8.8% and 9.5% in Group A and Group B, respectively, in PCOS women and 14% and 13% in women with unexplained infertility. Conclusion: Addition of single dose of uFSH improves pregnancy outcome particularly in anovulatory infertility (WHO II). Correction of unexplained infertility may need more than simple correction of possible subtle ovulatory effect.

Asha Baxi, Manila Kaushal, HK Karmalkar, Peeti Sahu, Pooja Kadhi, Baxi Daval
May-August 2010, 3(2):108-110
DOI:10.4103/0974-1208.69333  PMID:21209757
Expectant management for tubal heterotopic pregnancy could be considered as a successful option in a symptom-free patient where the ectopic embryo has a limited craniocaudal length with no cardiac activity. We report the obstetric outcome after expectant management for a right tubal heterotopic pregnancy. Heterotopic pregnancy was first recognized at 6 weeks gestation in a 32-year-old salpingectomized woman with an 8-year history of subfertility who conceived after in utero transfer of three embryos obtained by in vitro fertilization. Expectant management and close ultrasonographic and clinical monitoring were done. The intrauterine pregnancy proceeded unremarkably. A cesarean section was performed for breech presentation, and it allowed the delivery of a healthy 2260-g male infant. The examination of the adnexa showed a pre-rupture of the right fallopian tube.

Correlation of human sperm centrosomal proteins with fertility
Indira Hinduja, Nishitha B Baliga, Kusum Zaveri
May-August 2010, 3(2):95-101
DOI:10.4103/0974-1208.69344  PMID:21209754
Objective: The centrosome is the microtubule organizing center (MTOC) paternally inherited by the zygote during fertilization. As the centrosome is located in the midpiece of the sperm tail, we presume that oligoasthenozoospermic sperm samples should also have abnormal concentrations of centrosomal proteins. This study therefore aims to determine if there is any correlation between sperm centrosomal proteins, centrin, a and g-tubulin, in sperm samples from normozoospermic and oligoasthenozoospermic men. Materials and Methods: Proteins were extracted from the normozoospermic and oligoasthenozoospermic sperm samples and analyzed by Western Blot and ELISA for centrin, α and γ-tubulin. Results: The levels of centrin, α and γ-tubulin are markedly lower in oligoasthenozoospermic sperm samples as compared to the normozoospermic sperm samples. Conclusions: Lower centrosomal protein expression in sperm samples of oligoasthenozoospermic infertile males may be a possible cause for their reduced fertility status. Further studies on these proteins are warranted to design rational approaches for the diagnosis and treatment of male infertility.

Transfer of human frozen-thawed embryos with further cleavage during culture increases pregnancy rates
Bharat V Joshi, Manish R Banker, Pravin M Patel, Preeti B Shah
May-August 2010, 3(2):76-79
DOI:10.4103/0974-1208.69340  PMID:21209750
Aim: To compare the pregnancy rate following transfer of frozen-thawed embryos with or without overnight culture after thawing. Settings and Design: This is a retrospective analysis of frozen-thawed embryo transfer (FET) cycles performed between January 2006 and December 2008. Materials and Methods: Out of 518 thaw cycles, 504 resulted in embryo transfers (ETs). Of the total FET cycles, 415 were performed after an overnight culture of embryos (group A); and in 89 cycles, ET was performed within 2 hours of embryo thawing (group B). Statistical Analysis: The data were statistically analyzed using chi-square test. Results: We observed that with FET, women ≤30 years of age had a significantly higher (P=0.003) pregnancy rate (PR=28.9%) as compared to women >30 years of age (17.5%). A significantly higher (P<0.001**) pregnancy rate was also observed in women receiving 3 frozen-thawed embryos (29%) as compared to those who received less than 3 embryos (10.7%). The difference in PR between group A (PR=24.3%) and group B (PR=20.3%) was not statistically significant. However, within group A, ET with cleaved embryos showed significantly ( P≤0.01) higher pregnancy rate compared to the uncleaved embryos, depending on the number of cleaved embryos transferred. Conclusion: No significant difference was noticed between FETs made with transfer of embryos with overnight culture and those without culture. However, within the cultured group, transfer of embryos cleaved during overnight culture gave significantly higher PR than transfers without any cleavage.
