The androgenic polycystic ovary.

R B Greenblatt, V B Mahesh

    American Journal of Obstetrics and Gynecology
    |July 1, 1976
    PubMed
    Summary

    Polycystic ovary syndrome (PCOS) involves excessive androgen production from the ovaries. This study hypothesizes that adrenal hyper-responsiveness drives PCOS by creating an imbalance in the hypothalamic-pituitary axis, leading to ovarian stimulation.

    Area of Science:

    • Endocrinology
    • Reproductive Medicine
    • Gynecology

    Background:

    • Polycystic ovary syndrome (PCOS) is characterized by the ovaries' capacity for excessive androgen production.
    • The precise etiology of PCOS remains debated, with theories including hypothalamic-pituitary dysfunction and intrinsic ovarian enzyme defects.

    Purpose of the Study:

    • To propose a novel hypothesis for the pathogenesis of PCOS.
    • To explain the mechanism leading to the "androgenic polycystic ovary".

    Main Methods:

    • This study presents a theoretical model and hypothesis.
    • It integrates existing knowledge on hormonal regulation and ovarian function.

    Main Results:

    • The proposed hypothesis suggests an inherently sensitized adrenal gland as a primary driver of PCOS.
    • Excessive adrenal androgen secretion leads to hypothalamic-pituitary axis imbalance.
    • This imbalance results in tonic stimulation of the ovaries, culminating in the characteristic androgen excess of PCOS.

    Conclusions:

    • The adrenal gland's role in PCOS pathogenesis warrants further investigation.
    • This hypothesis offers a unifying explanation for the observed hormonal abnormalities in PCOS.
    • Understanding the adrenal contribution may lead to new therapeutic strategies for PCOS.
