OBJECTIVE: The critical phase of perimenopausal period is marked by a reduction in estrogen levels, leading to various clinical issues (vasomotor and neurodegenerative symptoms, increased osteoporosis risk and cardiovascular risk). These complex clinical scenarios pose challenges to clinicians in providing the right support for diagnosis and treatment. A group of Italian cardiologists, endocrinologists, and gynecologists conducted a survey among expert colleagues to assess consensus on controversial issues and best practices for screening and treating peri- and postmenopausal women...

OBJECTIVE: To analyze the impact of thyroid autoimmunity (TAI) on reproductive outcome parameters of ICSI cycles as compared to TAI negative ICSI cycles. DESIGN: In this single IVF center retrospective study 86 infertile women with elevated TPOAb or TGAb levels, but euthyroid after thyroxine replacement (study group), were compared to 69 female patients with no thyroid abnormalities (controls). Following ICSI treatment fertilization rate (FR), clinical pregnancy rate (CPR), miscarriage rate (MR) and live birth rate (LBR) were analyzed...

A 9-year-old Thoroughbred mare with normal external genitalia and regular oestrus symptoms was gynecologically examined prior to insemination. This primary examination revealed the presence of a hypoplastic uterus and the lack of normal ovaries, and the mare was therefore subjected to more detailed diagnostics, including endocrinological, genetic, and clinical tests. Diagnostic imaging with the use of ultrasonography and endoscopy confirmed the underdevelopment of internal genitalia. Analysis of circulating sex hormones revealed very low concentrations of progesterone and oestradiol...

INTRODUCTION: Predictive models have been used to aid early diagnosis of PCOS, though existing models are based on small sample sizes and limited to fertility clinic populations. We built a predictive model using machine learning algorithms based on an outpatient population at risk for PCOS to predict risk and facilitate earlier diagnosis, particularly among those who meet diagnostic criteria but have not received a diagnosis. METHODS: This is a retrospective cohort study from a SafetyNet hospital's electronic health records (EHR) from 2003-2016...

BACKGROUND: To guarantee the delivery of thorough and scientifically supported menopausal care, it is imperative to allocate resources towards ongoing education and training for physicians. Therefore, it is essential to assess the attitudes, practices, and obstacles faced by physicians in Saudi Arabia when it comes to menopausal hormone replacement therapy (HRT). METHOD: An online survey was conducted from June to September 2023 to investigate the attitudes, practices, and barriers of physicians in Saudi Arabia, regarding menopausal HRT...

Obesity is not a choice or a result of lack of willpower, but a multifactorial, chronic, progressive, and relapsing disease. During menopause, hormonal and body composition changes lead to greater visceral adiposity, that aggravates women's health at a cardiometabolic, mechanic and mental level. Adiposity has been identified as an important modifier of reproductive hormones. During female midlife, obesity has been associated with menstrual cycle alterations (anovulatory cycles ending with abnormal bleedings), menopausal symptoms including hot flashes, poor quality of sleep, aches and joint pain, genitourinary symptoms, and reduced quality of life...

OBJECTIVE: Medroxyprogesterone acetate (MPA) may increase the risk of atherosclerosis during hormone replacement therapy (HRT); therefore, the effect of progestogens other than MPA on atherosclerotic lesions requires evaluation. Adhesion of monocytes to vascular endothelial cells is an important early step in atherosclerosis progression. MCP-1 is a key chemokine that promotes monocyte migration and adhesion to vascular endothelial cells. In this study, we investigated the effects of dienogest (DNG), an alternative progestogen, on monocyte adhesion and cytokine expression in human umbilical vein endothelial cells (HUVECs)...

OBJECTIVE: Comparison of hormonal, metabolic and inflammatory markers of glutathione with metformin and Diane-35 in a rat model of PCOS induced by dehydroepiandrosterone. METHODS: Twenty-five female rats were randomized into four groups. Group 1 was administered a subcutaneous dose of 0.2 ml saline/day. Group 2 was given 0.2 ml of 1% carboxymethyl cellulose (CMC)/day orally for 28 days. A PCOS model was established with DHEA in rats. Group 3 was given 4...

OBJECTIVE: Bone mineral density (BMD) is typically reduced in patients with female athlete triad (FAT) and anorexia nervosa (AN). However, bone health in most patients with functional hypothalamic amenorrhoea (FHA), who may not suffer from severe energy deficiency, has not received adequate attention in clinical practice. This study aimed to investigate BMD and its association with clinical and endocrine features in individuals with FHA and to provide clinical evidence for improving bone loss and preventing osteoporosis in FHA...

OBJECTIVE: The purpose of this study was to explore the correlation between inflammatory indicators and blood lipids and to further provide a theoretical basis for the diagnosis and treatment of clinical polycystic ovary syndrome (PCOS). METHODS: Whole-blood cell counts and hormone and blood lipid levels were measured in 110 patients with PCOS and 126 healthy women. The differences in the above levels and the correlation between inflammation and blood lipid levels in the two groups were determined, and classified according to BMI...

OBJECTIVE: To assess the impacts of Platelet-Rich Plasma(PRP) and Granulocyte Colony-Stimulating Factor(G-CSF) on a rat model with induced ovarian follicular damage caused by cyclophosphamide(Cy). MATERIALS AND METHODS: Forty-two Sprague-Dawley rats were randomly allocated into seven distinct groups as; Group 1(control): NaCl intraperitoneal (IP) injection was administered on days D1, D7, and D14. Group 2(Cy): Cy IP injection on D1 + NaCl IP injection on D7 and D14 were administered...

PURPOSE OF REVIEW: This review presents the epidemiology of mental health conditions among reproductive aged people, common adverse reproductive outcomes, the hormonal profile of contraception and its relationship with psychiatric outcomes, and updated information for clinicians providing contraceptive counselling for this population. RECENT FINDINGS: There is variability among contraceptive behaviours and patterns across those who have mental health conditions, impacting reproductive, psychiatric, and perinatal outcomes...

OBJECTIVE: Underdiagnosis is an important issue in genetic lipodystrophies, which are rare diseases with metabolic, cardiovascular, gynecological and psychological complications. We aimed to characterize the diagnostic pathway in these diseases from the patients' perspective. DESIGN: Cross-sectional study conducted through a self-reported patient questionnaire. METHODS: Patients with genetic lipodystrophy were recruited throughout the French national reference network for rare diseases of insulin secretion and insulin sensitivity...

Endometriosis and polycystic ovary syndrome (PCOS) are common gynecological disorders that constitute a significant burden of disease in women of fertile age. The disorders share a link to female reproduction and infertility; however, divergent effects on menstrual cycle, related hormones, and body composition have been proposed. Disorders of the thyroid gland including abnormal thyroid dysfunction (hyperthyroidism or hypothyroidism) and/or markers of thyroid autoimmunity similarly show a female predominance and onset in younger age groups...

BACKGROUND: Testosterone plays a key role in women, but the associations of serum testosterone level with gynecological disorders risk are inconclusive in observational studies. METHODS: We leveraged public genome-wide association studies to analyze the effects of four testosterone related exposure factors on nine gynecological diseases. Causal estimates were calculated by inverse variance-weighted (IVW), MR-Egger and weighted median methods. The heterogeneity test was performed on the obtained data through Cochrane's Q value, and the horizontal pleiotropy test was performed on the data through MR-Egger intercept and MR-PRESSO methods...
