Polycystic ovary syndrome is the most common endocrine disease in reproductive age, characterized by menstrual alterations, clinical or biochemical hyperandrogenism, and ultrasound-identified ovarian cysts. The neuroendocrine and metabolic alterations that accompany this condition involve the desensitization of the hypothalamus-pituitary-ovary axis, steroidogenesis and hyperandrogenism; recently, the role of insulin resistance has been explored. Hyperandrogenism has been established to be the main cause of polycystic ovary syndrome, due to enzymatic alterations in the steroidogenic pathway that cause luteinizing hormone over-stimulation because of quick pulses generated by gonadotropin-releasing hormones. Various growth factors of and cytokines inhibit the conversion of androgens into estrogens; activin and prostaglandins are also involved, even high levels of insulin participate in the characteristic deregulation of this syndrome.

Introduction: A variety of hypoglycaemic drugs are used to treat polycystic ovarian syndrome (PCOS), but their efficacy remains insufficient. Glucokinase activators (GKAs) are a unique class of hypoglycaemic medications with emerging potential, notably in significantly reducing insulin resistance (IR). Nevertheless, the efficacy of GKAs in treating PCOS, particularly in the absence or presence of IR, remains uncertain.

Background: Granulosa cell proliferation and survival are essential for normal ovarian function and follicular development. Long non-coding RNAs (lncRNAs) have emerged as important regulators of cell proliferation and differentiation. Nuclear paraspeckle assembly transcript 1 (NEAT1) has been implicated in various cellular processes, but its role in granulosa cell function remains unclear.

Purpose: Women with polycystic ovary syndrome (PCOS) show greater heterogeneity in ovarian responses during ovarian stimulation. We aimed to investigate the potential predicting factors among individualized basic parameters that affect poor or hyper ovarian responses in PCOS patients.
Methods: We retrospectively screened 2058 women with PCOS who underwent their first cycle of in vitro fertilization/intracytoplasmic sperm injection.
To investigate the effect of D-chiro inositol (DCI) supplementation on perinatal outcomes in pregnant women at high risk of gestational diabetes mellitus (GDM), we conducted a prospective, randomized, placebo-controlled study. Eligibility criteria included women aged ≥ 35 years old, with a pre-pregnancy body mass index ≥ 24 kg/m, having a family history of type 2 diabetes, having a history of GDM, polycystic ovary syndrome, or a history of delivering macrosomia infants. Participants who were recruited at a gestational age of 12-16 weeks, were randomly to receive either DCI 500 mg twice daily or to receive a placebo for 12 weeks.

Background Polycystic ovary syndrome (PCOS) poses a significant health concern among reproductive-aged women and is characterized by ovarian dysfunction, hyperandrogenism, and insulin resistance. This study aims to assess the efficacy and safety of metformin and myo-inositol combination therapy compared to metformin monotherapy in patients with PCOS. Materials and methods This was a phase III, double-blind, randomized controlled clinical trial.
