Purpose: To establish the prevalence of acanthosis nigricans (AN) within the context of polycystic ovary syndrome (PCOS) and its associations with obesity, insulin resistance, insulinemia, and metabolic syndrome (MS).
Methods: A cross-sectional prospective study was conducted on 100 patients with PCOS diagnosed according to the Rotterdam Consensus (2003). The skin test included, in addition to the detection of the presence of AN, the presence of hirsutism (score ≥ 8) and acne. In addition to clinical and biochemical data, we investigated cardiovascular risk factors present in MS such as abdominal circumference, obesity, hypertension and HDL and triglyceride levels. Insulin resistance was determined by the HOMA-IR test.
Results: The prevalence of AN (53%) was significantly correlated with hirsutism (p = 0.02), body mass index (p < 0.01), basal insulinemia (p < 0.01), (HOMA-IR) (p < 0.01), and MS (p < 0.01). The prevalence of MS reached 36% and was significantly associated only with AN (p < 0.01). Although diabetes mellitus was absent, there was a significant association of altered HOMA-IR (p < 0.01) with MS (p < 5%) and AN (p < 0.01).
Conclusion: AN is part of the severe phenotypic profile of PCOS as an additional predictable sign of the risks of cardiovascular disease.

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.

Objective: This present study aimed to measure platelet factor 4 (PF4) protein level in follicular fluid of patients with polycystic ovary syndrome (PCOS) and analyzed the correlation between follicular PF4 level with clinical characteristics.
Methods: Sixty-seven women (36 PCOS patients vs. 31 non-PCOS women) were enrolled in the study.

Polycystic ovary syndrome (PCOS) is a highly prevalent endocrine disorder characterized by intertwined reproductive and metabolic abnormalities. While its causal origins remain incompletely understood, accumulating evidence suggests metabolic dysfunctions-manifested by insulin resistance, obesity, hyperglycemia, and dyslipidemia-as key contributors to the pathogenesis and progression of PCOS. Emerging interventions targeting these metabolic disturbances, including caloric restriction, GLP-1-based therapies, and bariatric surgery, have shown efficacy in alleviating PCOS symptoms and potentially blocking their inheritance.

Polycystic ovary syndrome (PCOS) is a multifactorial endocrine disorder associated with vascular dysfunction and increased cardiovascular risk. This study aims to investigate the dysregulation of vascular tone in PCOS, focusing on the imbalance between vasodilators (nitric oxide [NO] and apelin) and vasoconstrictors (noradrenaline and reduced prostacyclin). By examining these factors, the study seeks to elucidate their contribution to endothelial dysfunction and cardiovascular complications in PCOS patients.
