Abstract

Ninety-six infertile patients with endometriosis were studied and their endometriosis staged according to the Revised American Fertility Society Classification. Anovulation was detected in 19% of the 32 patients with Stage 1 disease but in only 3% in the remaining 64 patients with Stage II, III and IV disease. These results show that contrary to traditional belief, anovulation does occur in a significant number of patients with endometriosis, especially in minimal or mild disease.
