The polycystic ovary syndrome. 1. Pathogenesis

Area of Science:

• Reproductive endocrinology
• Gynaecology
• Metabolic disorders

Background:

• Hirsutism, oligomenorrhoea/amenorrhoea, and infertility are prevalent clinical issues encountered by gynaecologists and endocrinologists.
• Polycystic ovary syndrome (PCOS) is frequently diagnosed when hirsutism co-occurs with menstrual irregularities or infertility.
• Understanding the pathogenesis of PCOS is crucial for effective management and treatment strategies.

Purpose of the Study:

• To discuss the pathogenesis of polycystic ovary syndrome (PCOS).
• To provide a comprehensive overview of the underlying mechanisms contributing to PCOS development.
• To lay the foundation for understanding PCOS in a two-part series.

Main Methods:

• Literature review of existing research on PCOS pathogenesis.
• Synthesis of current understanding regarding hormonal, genetic, and environmental factors.
• Analysis of clinical presentations and their relation to underlying pathophysiology.

Main Results:

• Polycystic ovary syndrome (PCOS) is characterized by a complex interplay of factors leading to its development.
• Key features include hyperandrogenism, ovulatory dysfunction, and polycystic ovarian morphology.
• The pathogenesis involves genetic predispositions, insulin resistance, and altered gonadotropin secretion.

Conclusions:

• Polycystic ovary syndrome (PCOS) is a multifactorial endocrine disorder with significant clinical implications.
• Further research into PCOS pathogenesis is essential for advancing diagnostic and therapeutic approaches.
• This article serves as an introduction to the complex mechanisms underlying PCOS.
