The ovary is the main regulator of female fertility. Changes in maternal health and physiology can disrupt intraovarian homoeostasis thereby compromising oocyte competence and fertility. Research has only recently devoted attention to the involvement of dicarbonyl stress in ovarian function. On this basis, the present review focuses on clinical and experimental research supporting the role of dicarbonyl overload and AGEs (advanced glycation end-products) as key contributors to perturbations of the ovarian microenvironment leading to lower fertility. Particular emphasis has been given to oocyte susceptibility to methylglyoxal, a powerful glycating agent, whose levels are known to increase during aging and metabolic disorders. According to the literature, the ovary and the oocyte itself can rely on the glyoxalase system to counteract the possible dicarbonyl overload such as that which may occur in reproductive-age women and patients with PCOS (polycystic ovarian syndrome) or diabetes. Overall, although biochemical methods for proper evaluation of dicarbonyl stress in oocytes and the ovarian microenvironment need to be established, AGEs can be proposed as predictive markers and/or therapeutic targets in new strategies for improving reproductive counselling and infertility therapies.

Actuality. Ovarian insufficiency can be diagnosed in more than 30% of reproductive age women with obesity. The role of leptin in the pathogenesis of ovarian insufficiency in obesity is not well understood and needs to be detalised. The aim of the study: to ivestigate the role of leptin in the pathogenesis of ovarian insufficiency in obesity. Materials and methods. 50 reproductive age females with BMI > 26.5 kg/m2 were studied. 10 healthy reproductive age females were used as control. Blood levels of leptin, gonadotropins, prolactin, sex steroid hormones were measured by immunoenzymatic assay and pelvic echoscopy were performed in all studied patients and co ntrols. Results. 72% of obese women had signs of ovarian insufficiency, such as ovarian enlargement and increased antral follicular count. The level of leptin did not correlate with the presence or absence of ovarian insufficiency in our patient group. The positive correlation between leptin level and BMI, luteinizing hormone (LG) and oestradiol and negative correlation between leptin level and follicular stimulating hormone (FSH) were revealed. Conclusion. The results of our study do not support the hyperleptinemia as the main cause of ovarian dysfunction in alimentary obesity. The most potential reason of ovarian dysfunction in these women could be ovarian or non-ovarian origin hyperoestrogenia leading to premature LG piques, and, thus, disturbing folliculogenesis in ovaria.

Ovarian Syndrome

The Polycystic ovarian syndrome affects 6-15 % of reproductive age women worldwide. And recently the changing life styles and rising obesity worldwide have contributed to a rise in the incidence of PCOS. Though there are many issues with PCOS post conception. PCOS women are at increased risk of early pregnancy loss which is approx. three fold as compared to the women without PCOS. After successfully crossing the first trimester, they are at risk of developing pre- eclampsia, GDM, preterm birth and birth of small for gestational age infant. Also higher incidence of multiple pregnancies is there and the risks associated with them. All these leading to higher rate of c -section delivery. So, proper understanding of these risks, informing and counseling the patients regarding them facilitate closer maternal and fetal surveillance and help improving the outcome of pregnancy.

Endometriosis is a chronic, gynecologic disease affecting 6 to 10% of reproductive age women. Pelvic pain, dyspareunia, and infertility are the most common symptoms of endometriosis that can have a significant impact on patients’ lives. Although the etiology remains largely unknown, the role of estrogens in the development and growth of endometriosis is well characterized. Medical and surgical therapies are the two cornerstones of endometriosis management. Following diagnosis of endometriosis, treatment options will be dependent on patient preference (ie, seeking pain relief versus fertility treatment). Future research aimed at targeting altered molecular pathways in patients with endometriosis will hopefully help mitigate the burden of this debilitating disease.

Background: Infertility affects about 10-15% of couples of reproductive age groups. The current evidence indicates a 9% prevalence of infertility with 56% of couples seeking medical care. Hysterolaparoscopy provides a comprehensive investigative procedure in which various factors causing female infertility can be assessed at one sitting.Methods: A total 100 infertile women between 20-40 years of age including primary and secondary infertility were evaluated. Patients would be investigated thoroughly for infertility and in preparation for anaesthesia. Tests include follicular study, Ultrasound pelvis. Hysterolaparoscopy was performed in the pre ovulatory period between days 6-10 of the cycle for infertility evaluation.Results: In the present study out of 100 cases for infertility evaluated, primary infertility were 57(57%) and secondary infertility were 43(43%). In our study out of 100 patients, Hysterolaparoscopy showed tuberculosis in 24 (24%) patients, remaining were endometriosis, polycystic ovarian syndrome, congestion, intra-pelvic adhesions, hydro-salpinx.Conclusions: It is concluded that while treating the causes of female infertility combined simultaneous diagnostic laparoscopy and hysteroscopy should be performed in all infertile patients as” seeing is believing” and if any pathologies found to be operable the gynaecologist can perform operative hystero-laparoscopy at that time, hence anticipating the pathologies after pre-operative work up is very important.

Background: PCOS is one of the most common endocrine disorder in women of reproductive age, it affects about 5-10% of women of reproductive age. It is characterized by chronic anovulation, hyperandrogenism, and insulin resistance. 30-40% of PCOS women have impaired glucose tolerance.Methods: This was prospective observational study carried out on 100 patients of PCOS visiting outpatient Department of Obstetrics and Gynecology, BRD Medical College, Gorakhpur from 1st July 2018 to 30th June 2019. Patients were diagnosed as PCOS on basis of Rotterdam criteria. In these 100 patients, oral inositol 2 gm twice daily was given for 3 months to 6 months depending upon the response of the patient and patients were examined every 4 week for menstrual regularity, acne improvement, hirsutism, spontaneous ovulation and pregnancy.Results: With inositol supplementation, menstrual abnormality corrected in 80% cases, 45% cases having acne improved. Ovulation occurred in 75.5% cases and 66.6% cases conceived with inositol supplementation.Conclusions: Insulin resistance is the basic pathophysiology for PCOS hence inositol supplementation is supposed to be very good medicine for management of PCOS to improve insulin sensitivity. Inositol leads to improvement in regularity of menstrual cycle, insulin resistance, hyperandrogenic features like hirsutism, acne, restores ovulation and improves oocyte quality.

Polycystic ovarian syndrome (PCOS) considers as the most common disorder among women during reproductive age. Its common features involve hyperandrogenism, chronic anovulation, and weight gain. Till now, the pathogenesis of PCOS stay unknown, and there is evidence considered PCOS as a low-grade inflammatory disease. Polycystic ovarian syndrome is associated with a variety of endocrine and metabolic disturbances. The present study was designed to detect the role of (CTLA-4) gene polymorphism (rs733618) with PCOS. A total of 60 PCOS patients and 30 healthy women, matching in average age and body mass index (BMI), were enrolled in this study. Patients with PCOS were attend to AL - Nahrain University High Institute for Infertility Assisted Reproductive Technology, in Baghdad between Septembers to December/2018. Blood samples were aspirated from both groups to detection (CTLA-4) gene polymorphism (rs733618) by tetra-primer amplification-refractory mutation system based on real time polymerase chain reaction (ARMS-qPCR). The obtained results revealed normal genotyping for both groups. The result of current study confirms that there is no role of (CTLA-4) gene polymorphism (rs 733618) in PCOS.

Ovarian Syndrome

Polycystic ovary syndrome is the most common heterogeneous endocrine abnormality in women in the reproductive age. The syndrome remains an enigmatic disorder because the aetiology is still unclear. Familial aggreagation is relatively common among patients with polycystic ovary syndrome suggesting a significant genetic component, although the way of inheritance has not been established firmly. The authors review the relevant medical literature and suggest that genetic and environmental factors play a role in the development of polycystic ovary syndrome. To date, no gene has been identified that causes or contributes substantially to the development of a polycystic ovary syndrome phenotype. Polycystic ovarian syndrome is considered to be an oligogenic disorder in which the interaction of a number of genetic and environmental factors determines the heterogeneous clinical and biochemical phenotype. To summarize current evidence the authors conclude, that when we are able to identify and then modify environmental determinants, then we will be able to safeguard better the health of those patients who are predisposed to disease development due to genotype or previous environmental effects.

Actuality of the study. Ovarian insufficiency is present in more that 30% of reproductive age women. The role of leptine and insuin resistance in the pathogenesis of ovarian insufficiency is not yet established and has to be clarified. The aim of the study to investigate the role of hyperleptinemia, insulin resistance and hyperestrogenemia in the pathogenesis of ovarian insufficiency in obesity.Materials and methods. Fifty reproductive age women with BMI > 25,6 kg/m2 were studied. Ten healthy reproductive age women were included as controls. The plasma level of leprin, honadotropins, prolactin, insulin and sex steroid hormones assayed by immunoenzyme analysis, morning fasting blood glucose and the glucose level after glucose tolerance test, pelvic echography, “whole body” program of dual x-ray absorptiometry were studied in both patients and controls.Results. Thirty-six out of 50 women had signs of ovarian insufficiency. The presence and severity of ovarian insufficiency did not correlate with the level of leptin in blood or with insulin resistance. The positive correlation between oestradiol level and both presence and severity of ovarian insufficiency could be demonstrated.Conclusion. The results of our study do not support the hyperleptinemia and insulin resistance as the main cause of ovarian insufficiency in alimentary obesity. The most potential reason of anovulation in these women could be hyperoestrogenia due to increased conversion of androgens into oestrogenes in fat tissues and ovaria.
