Article Abstract
Polycystic ovary syndrome (PCOS) is characterized by hyperandrogenism, oligo-anovulation and polycystic ovarian morphology, with metabolic dysfunction from insulin resistance and abdominal fat accumulation worsened by obesity. As ancestral traits, these features could have favored abdominal fat deposition for energy use during starvation, but have evolved into different PCOS phenotypes with variable metabolic dysfunction. Adipose dysfunction in PCOS from hyperandrogenemia and hyperinsulinemia likely constrains subcutaneous (SC) fat storage, promoting lipotoxicity through ectopic lipid accumulation and oxidative stress, insulin resistance and inflammation in non-adipose tissue. Recent findings of inherently exaggerated SC abdominal stem cell development to adipocytes in women with PCOS, and PCOS-like traits in adult female monkeys with natural hyperandrogenemia, imply common ancestral origins of PCOS in both human and nonhuman primates.

Myo-inositol Supplementation to Prevent Pregnancy Complications in Polycystic Ovary Syndrome: A Randomized Clinical Trial.

Importance: Pregnant individuals with polycystic ovary syndrome (PCOS) present with a higher risk of pregnancy complications, including gestational diabetes, preeclampsia, and preterm birth. Myo-inositol supplementation may reduce these risks.
Objective: To determine whether daily supplementation with myo-inositol during pregnancy among individuals with PCOS reduces the risk of a composite outcome of gestational diabetes, preeclampsia, and preterm birth.

Background: Polycystic ovary syndrome (PCOS) is one of the most prevalent endocrine system disorders affecting reproductive-aged women of all races and ethnicities. A high prevalence of obesity exists in women with PCOS, who are also vulnerable to attrition from weight management programs. Despite recommendations the implementation of multidisciplinary approaches in weight management programs, there is a lack of literature evaluating their usage in their treatment programs.

The aim of this study is to investigate the characteristics and etiology of endometrial hyperemia in patients with polycystic ovary syndrome (PCOS) through two complementary approaches: clinical data analysis to characterize endometrial hyperemia and clinical trials to elucidate its underlying causes. ELISA was employed to quantify inflammatory mediators in endometrial tissue, while reverse transcription quantitative polymerase chain reaction (RT-qPCR) and Western blot analyses were conducted to assess the expression levels of molecules associated with endoplasmic reticulum stress (ERS). Additionally, RT-qPCR was used to determine the mRNA expression levels of HIF-1α, VEGF, and EPO.

Background: Determination of the estradiol hormone in urine is crucial for evaluating congenital adrenal hyperplasia, certain hormone-producing ovarian tumors, polycystic ovary syndrome, liver disease, pregnancy, and infertility. On the other hand, steroid hormones can have destructive effects on the environment, animals, and the endocrine system of humans. Consequently, accurately measuring this hormone's concentration in trace amounts is essential for environmental safety and human health.
