Update on polycystic ovary syndrome

Area of Science:

• Reproductive Endocrinology
• Gynecology
• Clinical Practice Guidelines

Background:

• Polycystic Ovary Syndrome (PCOS) is a prevalent endocrine disorder affecting reproductive-aged women.
• An international evidence-based guideline was published in 2018, offering comprehensive recommendations for PCOS assessment and management.
• This study focuses on clinically relevant recommendations and incorporates recent research published post-guideline.

Purpose of the Study:

• To review key clinical recommendations from the 2018 PCOS guideline for daily practice.
• To integrate findings from studies published after the 2018 guideline.
• To assess the potential impact of the guideline on clinical practice and identify areas for future research.

Main Methods:

• Review of the 2018 international evidence-based guideline for PCOS.
• Analysis of recommendations related to diagnosis (antral follicle count, hirsutism, adolescent diagnosis, ultrasonography use).
• Evaluation of treatment recommendations (oral contraceptives, metformin, ovulation induction agents) and comparison with subsequent studies.

Main Results:

• Updated diagnostic criteria include an increased antral follicle count cutoff (20) and revised hirsutism scoring (≥4-6).
• Adolescent PCOS diagnosis and ultrasonography use have specific age-related definitions (≥8 years post-menarche).
• First-line treatments include combined oral contraceptives for non-fertility indications and aromatase inhibitors for ovulation induction; metformin is recommended for weight and metabolic management in specific adult patients.

Conclusions:

• The 2018 PCOS guideline introduced significant changes in diagnostic criteria and treatment strategies.
• The adoption and impact of these updated recommendations on clinical practice remain to be fully determined.
• Further research is essential for a comprehensive understanding and improved management of PCOS patients.
