Polycystic ovary syndrome (PCOS) is a primary endocrinological disorder in women of reproductive age that is characterized by androgen excess and ovulatory irregularities. This syndrome is associated with adipose tissue dysfunction, an elevated risk of insulin resistance, hyperinsulinemia, obesity, and type 2 diabetes. Adipocyte dysfunction affects the secretion of adipokines and pro-inflammatory cytokines. Nevertheless, adipose tissue is not an exclusive source of adipokines as it can also be produced locally by reproductive tissues. Although adipokines have been recognized in the development of PCOS, the role of oncostatin M (OSM), a multifaceted adipokine, remains unclear. Current evidence suggests that this cytokine is associated with key aspects of the syndrome, including obesity, insulin resistance, hyperandrogenism, and inflammation. However, the data are often contradictory, likely due to variations in study designs, methodologies, and species differences. By investigating the link between OSM and PCOS-associated issues, this review identified the potential role of this adipokine in PCOS pathogenesis. This underscores the need for further research to clarify its predominant effects and assess its relevance as a therapeutic target.
Abstract Objective Numerous studies have indicated that the level of the Anti-Müllerian hormone (AMH), one of the main markers for the ovarian reserve, does not fluctuate throughout a menstrual cycle, while some studies have rejected this finding. The purpose of this systematic and meta-analysis study is to consensus on all contradictory studies that have measured AMH levels throughout the menstrual cycle and to investigate the exact extent of AMH variation in a cycle. Methods The protocol for this meta-analysis was registered at PROSPERO before data extraction. Relevant studies were identified by systematic search in PubMed, ScienceDirect, Embase, Cochrane Library, and Google Scholar with no limitation on publication date. Longitudinal studies which have evaluated AMH levels in the follicular and luteal phases of an unstimulated (natural) menstrual cycle in healthy women without endocrinology or ovarian disorders were included. We used the JBI Critical Appraisal Checklist for assessing the quality of studies found eligible for meta-analysis. Results A total of 11 studies involving 733 women with regular menstrual cycles were included. The results showed that the AMH level in the follicular phase was significantly higher than in the luteal phase (95% Cl = 0.11 [0.01 to 0.21]; p < 0.05) and it varies about 11.5% from the luteal phase. The analysis of studies which had also examined the ovulatory phase ( n = 380) showed that the serum levels of AMH in the ovulatory phase (about 2.02 ng/ml) did not significantly vary compared to follicular (95% Cl = 0.11 [-0.10 to 0.33]; p = 0.30) and luteal (95% Cl = 0.06 [-0.08 to 0.20]; p = 0.43) phases. Conclusions According to the results of this study, AMH levels differ between follicular and luteal phases which might be due to ovarian response to the gonadotropins. It seems the phase of AMH measurement needs to be considered for interpretation of the serum AMH test.
Abstract Evidence suggests that COVID-19 may impair access to sexual and reproductive health services and safe abortion. The purpose of this systematic review was investigating the changes of abortion services in the COVID-19 pandemic era. We searched PubMed, Web of Science and Scopus for relevant studies published as of August 2021, using relevant keywords. RCT and non-original studies were excluded from the analysis and 17 studies of 151 included in our review. Requests to access medication abortion by telemedicine and demand for self-managed abortion were the main findings of identified studies. Women requested an abortion earlier in their pregnancy, and were satisfied with tele-abortion care due to its flexibility, and ongoing telephone support. Presenting telemedicine services without ultrasound has also been reported. Visits to clinics were reduced based on the severity of the restrictions, and abortion clinics had less revenue, more costs, and more changes in the work style of their healthcare providers. Telemedicine was reported safe, effective, acceptable, and empowering for women. Reasons for using tele-abortion were privacy, secrecy, comfort, using modern contraception, employing of women, distance from clinics, travel restrictions, lockdowns, fear of COVID-19, and political reasons (abortion prohibition). Complications of women using tele-abortion were pain, lack of psychological support, bleeding, and need to blood transfusions. The results of this study showed that using telemedicine and teleconsultations for medical abortion in the pandemic conditions may be extended after pandemic. Findings can be used by reproductive healthcare providers and policy makers to address the complications of abortion services.

BackgroundGestational diabetes mellitus (GDM) is the most common medical complication of pregnancy, and it can lead to complications for the mother and the infant/fetus. This was especially evident during the COVID-19 pandemic. Therefore, the present systematic review aimed to describe the changes in screening, diagnosis, management, and outcomes of gestational diabetes during the COVID-19 pandemic.MethodsThe systematic review was conducted from December 2019 until January 1, 2022. To find articles related to the purpose of the study, PubMed, Scopus, Web of Science, and WHO were searched using relevant and validated keywords using MeSH/Emtree.ResultsIn total, 675 entries were ascertained from the database inquiry, and 17 scholarly works were deemed suitable for inclusion in the final review. The salient conclusions derived from this review were as follows: (a) During the COVID-19 pandemic, there was a significant decrease in the use of OGTTs and a rise in the use of HbA1c assays for both GDM screening and diagnosing. (b) A predominant number of physicians incorporated some variation of telemedicine to remotely supervise and conduct follow-up evaluations of patients with GDM. Various strategies are presented for the provision of prenatal care to women afflicted with GDM, such as concentrating on high-risk demographics, the initiation of lifestyle modifications at early stages, and the implementation of remote patient monitoring techniques. The 'single test procedure' is identified as the most suitable for the preliminary screening of GDM. The OGTT should be assigned clinical precedence in patients at high risk during the ongoing COVID-19 pandemic. Additionally, Medical Nutrition Therapy (MNT) was established as the primary management strategy, and the most influential determinant of the transition from dietary adjustments to pharmacotherapy was the Fasting Blood Glucose (FBG) levels during the second trimester.ConclusionSuggested strategies for GDM screening and management during the pandemic integrated into routine antenatal care, emphasized the importance of remote diabetes education and technology utilization during health emergencies.
Sex steroids are powerful modulators of the immune system and they may affect the immune response and inflammatory consequences of COVID-19. This systematic review aims to explore the impact of sex steroids on COVID-19 mortality and complications. We looked up the keywords of the study in Scopus, PubMed, and Web of Science. All related original articles published in English, as of October 16, 2021, were reviewed to be included in our research. Concerns regarding the effect of sex hormones on COVID-19, eight full texts have been identified for the conclusion. In these studies, the relationship between estradiol and COVID-19 mortality has been mentioned. The most significant findings were the higher COVID-19 mortality rate in men, compared to women; also, in menopausal women compared to younger women and who received estradiol. In two studies, oral contraceptive pills had a protective effect on the morbidity of SARS-CoV-2 infection. In a randomized controlled trial, subcutaneous injection of progesterone in hospitalized men significantly reduced their symptoms and need for oxygen therapy. Hormone replacement therapy was positively associated with reducing COVID-19 symptoms. Although the results were insufficient for a conclusion, this study represents estrogen as an appropriate pharmacological method for preventing and diminishing the inflammation related to COVID-19 disease. However, future prospective studies and clinical trials are needed to clarify and approve this protective effect.
Abstract Background: Sexual health as an essential component of life, has been affected by COVID-19 pandemic. Changing in sexual life has consequences for couples and society. A critical review of current literature on sexual function in general populations will shed light on possible determinants as well as at-risk groups. Thus, the aim of this systematic review is to assess the consequences of COVID-19 on sexual and reproductive health. Methods/Design: A systematic review of literature on data reporting changings of individuals’ sexual life during the COVID-19 pandemic will be performed. The scientific databases of PubMed, Embase, Scopus, Web of Science, ScienceDirect, the World Health Organization, as well as protocols and guideline related to sexual health, behaviors, function and practices will be systematically searched from the onset of the disease in the world until August 15, 2021. We will consider, appraise, and synthesize studies including the change of sexual function and behaviour (physical, emotional, mental and relational health), SRH-care and services (contraception, birth control, STIs management), and sexual rights (gender-based and sexual minorities violence). Screening of search results and extraction of data from included studies will be conducted cooperatively by two authors. The quality of the studies will be appraised and documented. Results will be compiled and presented in evidence tables. Risk of bias (the quality assessment) will be evaluated by two review authors using the Critical Appraisal Skills Programme (CASP) tool. This protocol has been conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocols (PRISMA-P) guidelines. Also, this protocol is registered in PROSPERO with number CRD42021275387. Discussion: Given the potential impacts of the COVID-19 pandemic on the people’s sexual life and reproductive health, this review aims to provide accurate information on different aspects of sexual function and behavior in populations from various age groups, cultures, and sexual orientations sexual health and reproductive care delivery (contraception, and birth control, SDTs management) and sexual rights (gender-based and sexual minority, sexual violence) to provide a better understanding of COVID-19 pandemic’s effect on people’s sexual lives The findings could be used by health planners and health care providers to address the adverse effects of this period on reproductive health and sexual lives.
