Article Abstract
Polycystic ovary syndrome (PCOS) is an endocrine and metabolic disorder characterized by a clinical and/or biochemical hyperandrogenism. In addition, PCOS is also associated with the presence of ovarian cysts, anovulation, and menstrual abnormalities such as oligomenorrhea or amenorrhea. The aetiology of the syndrome is multifactorial and heterogeneous due to the interaction of genetic, hormonal, metabolic, and environmental factors, as well as the different phenotypes and responses to treatments exhibited by the patients. Considering this complex interaction, it is essential to continue with the research focused on the mechanisms involved in the development and maintenance of the pathology. The alteration in the pulsatile secretion of the gonadotropin-releasing hormone (GnRH) is considered to be one of the main causes that contributes to its onset. In this review, we discuss recent evidence about the role of the rostral periventricular area of the third ventricle (RP3V), the arcuate nucleus (ARC), and the ventromedial nucleus of the hypothalamus (VMH), key hypothalamic regions that regulate GnRH secretion, in the development of PCOS. In addition, we analyse the clinical, metabolic, and endocrine factors that interact in the patients with PCOS, offering a multifactorial perspective to improve our understanding of this disorder.

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.

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.
