Endometriosis was present in five out of six Rhesus monkeys who had to be sacrificed because of disease in a colony of 90. The monkeys lost appetite and became constipated. The abdomen was distended and often a pelvic mass could be palpated. At autopsy, 300-500 ml of blood-stained fluid was found in the abdomen together with intestinal or pelvic endometriosis. The ethiology of endometriosis in Rhesus monkeys is unknown. The most probable explanation is intraabdominal implantation of endometrial tissue through retrograde menstruation. The lesion is rare in animals in free ranging colonies. It is not known whether this is due to a higher frequency of pregnancies in animals with free access to matings or to its consequences, i.e. more infrequent menstruations.
在一个90只恒河猴的群体中，有6只因疾病不得不被处死，其中5只存在子宫内膜异位症。这些猴子食欲不振并出现便秘。腹部膨胀，常常能摸到盆腔肿块。尸检时，在腹部发现300 - 500毫升血性液体以及肠道或盆腔子宫内膜异位症。恒河猴子宫内膜异位症的病因尚不清楚。最可能的解释是子宫内膜组织通过逆行月经在腹腔内植入。在自由放养群体的动物中这种病变很少见。不知道这是由于能自由交配的动物怀孕频率较高，还是由于其后果，即月经更不频繁所致。
