Methods of detecting ovulation and conducting artificial insemination in great apes are reviewed and described. Ovulation time can be detected to some extent by measuring timing relative to such cyclic correlates as menstruation, perineal swelling, body temperature, viscosity of cervical mucus, and behavior (copulation, masturbation, aggressivity). The most precise methods are observation of ovarian morphology using laparoscopy or ultrasonography, but the most practical method for great apes is the use of recently developed rapid hemagglutination inhibition test for luteinizing hormone. Using this test, three chimpanzees and one gorilla have been successfully artificially inseminated. Artificial insemination in great apes involves collection of semen by automasturbation or rectal probe electro‐ejaculation. Females are anesthetized and fractionated ejaculate is placed on the cervical os. Complicating factors include potential effect of anesthesia, variation in semen quality, frequency of AI required, and the apparent inherent infertility potential of great apes and humans.
