An embryo was recovered surgically from a naturally ovulating, naturally inseminated Papio cynocephalus female on day 5 of gestation and transferred surgically to a naturally synchronized, nonmated Papio cynocephalus female on 20 March 1975. A male baboon weighing 875 grams was delivered by cesarean section on 5 September 1975, 174 days after estimated ovulation time.
