[The heterogeneity of micropolycystic ovary syndrome. 77 cases (author's transl)]

Seventy seven cases of micropolycystic ovaries were reviewed. All of the patients underwent either coelioscopy or wedge resection of the ovaries. It was thus possible to classify the patients into two groups on the basis of the size of the ovaries (MPCO-A, large ovaries, more than twice the normal size; MPCO-B, ovaries only slightly increased in size or normal). There were differences from a clinical, laboratory and therapeutic standpoint. In MPCO-A, spaniomenorrhea predominated, clinical hyperandrogenism was often absent and 17 ketosteroids lower. Response to hypothalamic gonadotrophic hormone liberation factor was explosive in luteotrophic hormone, but at 120 minutes levels were lower in MPCO-A than in MPCO-B. Wedge resection failed completely in 23% of cases of MPCO-A and in 66% of cases of MPCO-B. This study confirmed current concepts of the heterogeneity of MPCO syndrome.
