ObjectiveTo review the value of the baboon as a model for the study of endometriosis.Data identification and selectionStudies performed at the Institute of Primate Research in Nairobi, Kenya (1990-1994), and published in peer-reviewed journ…

BackgroundThis study was performed to test the hypothesis that endometriosis undergoes regression during pregnancy.MethodsThis study was performed on 11 baboons with histologically proven endometriosis, housed at the Institute of Primate Re…

OBJECTIVE: To determine the incidence of spontaneous endometriosis over a 32-month period in baboons with initially normal pelves. METHODS: In this observational longitudinal study, which was performed at the Institute of Primate Research, …

OBJECTIVE: To investigate how long an ovulation stigma remains visible as determined by serial laparoscopies performed during the luteal phase in baboons. SUBJECTS AND SETTING: Sixteen female baboons with a normal pelvis (n = 6) and with e…

In women with endometriosis, changes in peripheral blood and peritoneal fluid white blood cell (WBC) populations have been reported, but it is known whether these alterations are casually related to or a consequence of endometriosis. The pu…

This study was done to test the hypothesis that the incidence and recurrence of retrograde menstruation is higher in baboons with spontaneous endometriosis than in those without. A total of 399 laparoscopies was performed on 113 female babo…

ObjectiveTo test the hypothesis that a recent corpus luteum (CL) without fresh ovulation stigma (OS) can be found with a higher incidence and recurrence in baboons with endometriosis and is associated with a reduced egg recovery rate after …

ObjectiveTo test the hypothesis that spontaneous endometriosis is a progressive disease in baboons.Design and settingProspective cohort study, Institute of Primate Research, Nairobi, Kenya.ParticipantsTwelve baboons with histologically prov…

OBJECTIVES: To test the hypothesis that fertility is reduced in baboons with endometriosis. DESIGN: Prospective controlled follow-up study. SETTING: Institute of Primate Research, Nairobi Kenya. SUBJECTS: Seventy-one baboons, including 3…

BACKGROUND: It is not known whether stress affects the prevalence of endometriosis in women. Baboons with spontaneous endometriosis may be interesting models to study the human disease. For baboons, living in captivity is a period of chroni…

ObjectivesTo determine if microscopic endometriosis exists in visually normal pelvic peritoneum from baboons with and without endometriosis.DesignObservational histologic study at Institute of Primate Research, Nairobi, Kenya.SubjectsSevent…

This study was performed to test the hypothesis that anti-endometrial, lymphocyte-mediated cytotoxicity and natural killer (NK) activity are reduced in baboons with endometriosis when compared to animals with a normal pelvis. Lymphocyte-med…

ObjectiveThe Sampson hypothesis of retrograde menstruation as a cause of endometriosis was tested by determining the effect of intrapelvic injection of menstrual versus luteal endometrium on the incidence, peritoneal involvement, and stage …

This study was performed to document for the first time peritoneal fluid volumes and steroid hormone levels in baboons with and without endometriosis. A laparoscopy was carried out in 19 female baboons (11 with a normal pelvis and 8 with hi…

OBJECTIVE: To test the hypothesis that immunosuppression increases the development and progression of endometriosis in baboons. DESIGN: Experimental controlled study. SETTING: Institute of Primate Research, Nairobi, Kenya. PARTICIPANTS: …

To document the spontaneous evolution of endometriosis, a repeat laparoscopy was performed in 11 baboons after 10 and/or 12 months. The mean number of endometriotic lesions had increased significantly after 10 months (P less than 0.02) beca…

The prevalence of spontaneous endometriosis was investigated by laparoscopy in 52 baboons (Papio anubis and Papio cynocephalus) of proven fertility. Clinical endometriosis was diagnosed in 9 (17%) and 4 (8%) baboons with or without a previo…
