Stein and Leventhal: 80 years on.

Area of Science:

• Reproductive Endocrinology and Infertility
• Gynecology
• Endocrinology

Background:

• The 1935 Stein-Leventhal publication is recognized as a seminal work in reproductive endocrinology.
• It described a triad of symptoms: polycystic ovaries, hirsutism, and oligo/amenorrhea, linking previously disparate clinical observations.
• The report detailed a series of patients, establishing a distinct clinical entity.

Discussion:

• The publication's impact is evidenced by an exponential increase in related literature, with over 20,000 papers between 2001-2015.
• The inclusion of a potential therapy (bilateral ovarian wedge resection) and the disorder's prevalence contributed to its clinical adoption.
• The Stein-Leventhal syndrome gained a strong foothold in medical practice due to clear descriptions and prolific reporting by the authors.

Key Insights:

• The 1935 report was transformative, being the first to describe a syndrome characterized by polycystic ovaries, hirsutism, and menstrual irregularities.
• It connected symptoms previously considered separate, such as polycystic ovaries with menorrhagia and hirsutism with oligo/amenorrhea.
• The syndrome, now understood in various forms, affects a significant portion of women, estimated at 1 in 7–17 globally.

Outlook:

• Commemorating the 80th anniversary of the Stein-Leventhal report highlights its enduring legacy in understanding polycystic ovary syndrome (PCOS).
• Continued research builds upon this foundational work, exploring the complex pathophysiology and diverse manifestations of PCOS.
• The high prevalence underscores the ongoing importance of research, diagnosis, and management strategies for PCOS.
