The Influence of Study Quality, age, and Geographic Factors on Pcos Prevalence - A Systematic Review and Meta-Analysis.

Background: Polycystic ovary syndrome (PCOS) is a highly prevalent disorder with substantial burden, yet global epidemiological data remains limited.

Objectives: To estimate the PCOS prevalence globally.

Materials And Methods: We systematically searched PubMed and Embase for PCOS studies in unselected populations through February 2024.

The Value of Androgen Measures for Diagnosing Polycystic Ovary Syndrome (PCOS) in an Unselected Population.

Objective: Polycystic Ovary Syndrome (PCOS) is diagnosed by a combination of three features: hyperandrogenism (biochemical and/or clinical), ovulatory dysfunction, and polycystic ovarian morphology, usually detected by ultrasonography. Our study aimed to determine the need for androgen measurements by using hirsutism to establish hyperandrogenism for diagnosing PCOS in a medically unbiased population.

Materials And Methods: We utilized a pre-existing cohort of unselected (medically unbiased) females aged 18-45 years.

Evaluating the diagnostic accuracy of androgen measurement in polycystic ovary syndrome: a systematic review and diagnostic meta-analysis to inform evidence-based guidelines.

Background: Biochemical hyperandrogenism is a hallmark and diagnostic feature of polycystic ovary syndrome (PCOS). However, the most accurate androgen measurement for assessing biochemical hyperandrogenism in PCOS diagnosis remains uncertain.

Objective And Rationale: This systematic review aimed to assess different androgen measures [including total testosterone (TT), calculated free testosterone (cFT), free androgen index (FAI), androstenedione (A4), dehydroepiandrosterone sulfate (DHEAS), and dihydrotestosterone (DHT)] for accuracy in diagnosing biochemical hyperandrogenism in women with PCOS, to inform the 2023 International PCOS Evidence-based Guidelines.

How Frequently Is Ultrasound Required to Diagnose Polycystic Ovary Syndrome in a Clinical Population?

Polycystic ovary syndrome (PCOS) is a common endocrine condition, affecting up to 20% of reproductive aged women worldwide. Polycystic ovarian morphology (PCOM) may be present, but is not required for diagnosis. Our study seeks to evaluate the utility of ultrasound in diagnosing or excluding PCOS by 2023 International Guidelines Criteria.
