Polycystic ovary syndrome may result from multiple mechanisms, but full expression of the PCO syndrome with hyperandrogenic anovulation depends upon sustained LH drive and relative FSH deficiency. We have described possible intrinsic and extrinsic factors capable of modifying the hypothalamic-pituitary-ovarian axis. Available evidence suggests the presence of an intrinsic alteration in GnRH-LH drive. The long-term natural history of HAA is variable and depends on several factors including obesity, aberrations in insulin action, intrinsic ovarian function, and end-organ responsiveness to androgens. Figure 1 presents a conceptualization of the pathogenesis of PCOS diagramming the multiple modulators of its expression. Long-term suppression of androgens when fertility is not desired should modify the full expression of the PCO syndrome. It is important to appreciate that therapy with oral contraceptive agents has few drawbacks and many immediate and potential long-term benefits for women with HAA. This therapy may be of greatest benefit when started in adolescence prior to the progression of obesity, hirsutism, and thecal-stromal hyperplasia. Women with HAA represent a large subgroup of patients who require individualization of their health care with sensitivity to issues surrounding anovulation, obesity, hirsutism, and infertility.
