[Hormone levels, celioscopy and ovarian histology in the hirsutism-anovulation syndrome].

Among 50 women with hirsutism, spanio- or amenorrhoea and anovulation, coelioscopy and histological examination of ovarian biopsies showed that 26 had typically polycystic ovaries (PCO), 17 had "borderline ovaries" (BO)--i.e. apparently normal or subnormal but with histological abnormalities identical to those of PCO--and 7 had normal ovaries. The hormonal profiles of BO and PCO were very similar. An increase in LH or in LH response to LHRH, which is regarded as characteristic of polycystic ovarian disease, was only observed in 75% of women with PCO or BO. The PCO and BO detection value of simple basal LH determination was slightly enhanced by the LHRH test, and no further enhancement was observed after repeated LHRH injections. 38% of PCO's and 75% of BO's were associated with adrenal hyperandrogenism, as evidenced by a rise in dehydroepiandrosterone values. Thus, more than one half of hirsute and non-ovulating women have polycystic ovaries. Most of these can be diagnosed by hormonal investigations without having recourse to coelioscopy. However, some do not display, at least permanently, the hormonal profile characteristic of polycystic ovarian disease.
