Independent Variables for Determining the Cumulative Live Birth Rates of Aged Patients with Polycystic Ovary Syndrome or Tubal Factor Infertility: A Retrospective Cohort Study

ObjectiveTo assess whether women of advanced age (≥35 years) with polycystic ovary syndrome (PCOS) have the same cumulative live birth rate (CLBR) as their age-matched controls with tubal factor infertility and to determine the influencing factors on the CLBRs of aged women.DesignA retrospective cohort study.Setting and PopulationA total of 160 women of advanced age (≥35 years) with PCOS and 1073 women with tubal factor infertility were included in our study. All patients underwent their first fresh cycles and subsequent frozen cycles within in one year in our centre from 2015 to 2020.MethodsTo determine independent influencing factors on the CLBRs of these aged patients, a multivariable Cox regression model of CLBR according to the transfer cycle type was constructed. Main outcome measure(s): CLBRs.ResultThe Cox regression model of the CLBRs indicated that there was no significant difference between the PCOS group and the tubal infertility group in terms of advanced age (HR, 0.95; 95% CI, 0.71-1.27, P=0.732). The CLBR significantly decreased for women of advanced reproductive age up to 37 years of age (HR, 0.46; 95% CI, 0.39-0.56, P<0.001). The CLBR increased by 63% when more than ten oocytes were retrieved (HR, 1.63; 95% CI, 1.34-1.98, P<0.001). Patients with an AMH level above 32.13pmol/l were likely to have a 72%(HR, 1.72; 95% CI, 1.08-2.73, = 0.023) and 34% (HR, 1.34; 95% CI, 1.07-1.68, P=0.010)improvement in CLBR compared to those with an AMH below 7.85pmol/l and 7.85-32.12pmol/l, respectively.ConclusionDespite the higher number of oocytes retrieved in PCOS patients, the reproductive window is not extended for PCOS patients compared with tubal factor infertility patients. Age, AMH and the number of oocytes retrieved play crucial roles in the CLBRs of patients of advanced age (≥35 years).

Levels of Trace Elements in Erythrocytes as Endocrine Disruptors in Obese and Nonobese Women with Polycystic Ovary Syndrome

Introduction: Polycystic ovary syndrome (PCOS) is one of the most commonly recognized endocrinopathies in women. The literature lacks clear data that allow any meaningful conclusions to be drawn about the influence of trace elements in erythrocytes on the biochemical parameters of PCOS. Materials and methods: This study was conducted among 47 women meeting the Rotterdam criteria for the diagnosis of polycystic ovary syndrome. The research groups included women with PCOS with different BMI values (body mass index): obese women with PCOS (PCOS with BMI ≥ 30, mean BMI index 35.4 ± 4.4 kg/m2), nonobese PCOS women (PCOS with BMI < 30, mean BMI index 25.2 ± 2.8 kg/m2), and healthy control group (CG) with a mean BMI of 23.57 ± 0.9 kg/m2. The contents of trace elements in erythrocytes were determined with an inductively coupled plasma atomic emission spectrometer. Results: The only trace element showing significant differences in concentration between the studied groups was nickel (Ni). The level of nickel in the obese women with PCOS (BMI ≥ 30) was significantly higher than in nonobese women (BMI < 30). The content of other trace elements in erythrocytes did not differ significantly between the studied groups. Several significant correlations were found within each of the studied PCOS groups: in the group of obese women, the content of zinc (Zn) in erythrocytes positively correlated with prolactin, the content of magnesium (Mg) positively correlated with testosterone, and the content of manganese (Mn) negatively correlated with thyroid-stimulating hormone. In the group of nonobese women, Zn content correlated positively with testosterone, Ni with luteinizing hormone (LH) and estradiol, and Mg negatively correlated with estradiol. Conclusions: The relationship between the level of trace elements and the level of hormones suggests that, in obese women with PCOS, nickel may play a role in inhibiting the processes of folliculogenesis and ovulation. Research on trace elements and their relationship to ovulatory cycles and the development of PCOS may contribute to reducing the consequences of PCOS and, therefore, should be extended.

Treatment of Infertility in Women with Polycystic Ovary Syndrome in a Single Center Study

Background: Anovulatory infertility is caused by polycystic ovarian syndrome in 80 percent of patients. Preconception guidelines, such as lifestyle modification (weight loss) to avoid fetal neural tube abnormalities, and quitting smoking and drinking alcohol, are all part of the early treatment. A clomiphene citrate medication for timed intercourse is the first-line pharmacological treatment for producing ovulation. Exogenous gonadotropins or laparoscopic ovarian surgery are two options for second-line pharmaceutical treatment (ovarian drilling). Ovulation induction using clomiphene citrate or gonadotropins is effective, with a 70 % cumulative live birth rate. When laparoscopy is necessary, ovarian drilling should be done; this operation is usually successful in around half of the instances. Finally, when the previous interventions have failed, a high-complexity reproduction treatment (in vitro fertilization or intracytoplasmic sperm injection) is recommended. There is no evidence that metformin should be used routinely in the treatment of infertility in anovulatory women with polycystic ovary syndrome. Aromatase inhibitors show promise, but more research is needed to confirm their safety.Methods:This study was conducted in Department of gynecology and obstetrics, Dhaka Medical College Hospital, Dhaka, from January 2019 to December 2019. A total number of 100 patients with multiple myeloma were analyzed cytogenetically by interphase fluorescence in situ hybridization (iFISH). The collected data were analyzed by using the Statistical Package for Social Science (SPSS-24) for windows version 24.0.Conclusion:PCOS is a frequent syndrome and the most frequent cause of infertility. PCOS is defined as a syndrome with at least two of three of the Rotterdam criteria. A complete evaluation of the infertility is needed to exclude other causes of infertility..

Deconstructing a Syndrome: Genomic Insights into PCOS Causal Mechanisms and Classification

Polycystic ovary syndrome (PCOS) is among the most common disorders of reproductive-age women, affecting up to 15% worldwide, depending on the diagnostic criteria. PCOS is characterized by a constellation of interrelated reproductive abnormalities including disordered gonadotropin secretion, increased androgen production, chronic anovulation, and polycystic ovarian morphology. It is frequently associated with insulin resistance and obesity. These reproductive and metabolic derangements cause major morbidities across the lifespan, including anovulatory infertility and type 2 diabetes (T2D). Despite decades of investigative effort, the etiology of PCOS remains unknown. Familial clustering of PCOS cases has indicated a genetic contribution to PCOS. There are rare Mendelian forms of PCOS associated with extreme phenotypes, but PCOS typically follows a non-Mendelian pattern of inheritance consistent with a complex genetic architecture, analogous to T2D and obesity, that reflects the interaction of susceptibility genes and environmental factors. Genomic studies of PCOS have provided important insights into disease pathways and have indicated that current diagnostic criteria do not capture underlying differences in biology associated with different forms of PCOS. We provide a state-of-the-science review of genetic analyses of PCOS, including an overview of genomic methodologies aimed at a general audience of non-geneticists and clinicians. Applications in PCOS will be discussed, including strengths and limitations of each study. The contributions of environmental factors, including developmental origins, will be reviewed. Insights into the pathogenesis and genetic architecture of PCOS will be summarized. Future directions for PCOS genetic studies will be outlined.

Berberine alleviates LPS-induced apoptosis, oxidation, and skewed lineages during mouse preimplantation development

Female infertility is a heterogeneous disorder with a variety of complex causes, including inflammation and oxidative stress, which are also closely associated with the pathogenesis of Polycystic Ovary Syndrome (PCOS). As a new treatment for PCOS, berberine (BER), a natural compound from Berberis, has been clinically applied recently. However, the mechanisms underlying the association between BER and embryogenesis are still largely unknown. In this study, effects of BER on preimplantation development was evaluated by using both normal and inflammatory culture conditions induced by lipopolysaccharide (LPS) in the mouse. Our data first suggest that BER itself (25 nM) does not affect embryo quality or future developmental potency, moreover, it can effectively alleviate LPS-induced embryonic damage by mitigating apoptosis via ROS−/caspase-3-dependent pathways and by suppressing pro-inflammatory cytokines via inhibition of NF-κB signaling pathway during preimplantation embryo development. In addition, skewed cell lineage specification in inner cell mass (ICM) and primitive endoderm (PE) caused by LPS can also be successfully rescued with BER. In summary, these findings for the first time demonstrate the non-toxicity of low doses of BER and its anti-apoptotic and anti-oxidative properties on embryonic cells during mammalian preimplantation development.

HEALTH ORIENTATION AND DISORDERED EATING ATTITUDE IN WOMEN WITH POLYCYSTIC OVARY SYNDROME (PCOS)

Reproductive medicine in the field of health psychology deals with the psychological aspects of the reproductive system and its consequences. Reproductive medicine provides an opportunity to understand the process of the menstrual cycle, pregnancy, hormonal conditions and illnesses, sexual behaviour, menopause by not merely from a biological point of view but also in light of psychological and social processes. Aline to this view, the study explored health orientation and disordered eating attitude in women diagnosed with Polycystic Ovary Syndrome (PCOS). The study captured the health-related behavior and attitude, which is a key component of the development of psychological distress in PCOS. It also examined the differences for the same in PCOS and Non-PCOS women. Total of eighty women, from the age group of 18-30 (young adults) were included in the study. The results highlighted, a significant difference among PCOS and Non-PCOS women on health image concern, health anxiety, health esteem and confidence, health expectations and health status. Finding also implied that there was a significant difference in disordered eating attitude of women diagnosed with PCOS and healthy women. These findings could have a significant implication for prevention, clinical practice and intervention in women with PCOS. The incorporation of medical and psychological actions to enhance their health-related quality of life may help these women.
