The prevalence of spontaneous endometriosis in the baboon (Papio anubis, Papio cynocephalus) increases with the duration of captivity

Abstract

The results indicate that the prevalence of endometriosis increases with the time spent in captivity. This trend may be explained by more menstrual cycles uninterrupted by pregnancy in captive than in wild baboons, and possibly also by age-related factors or by captivity-associated stress.
