title: The effect of heterologous gonadotropins on the fecundity of rhesus monkeys.
abstract: Ovarian stimulation with heterologous gonadotropins over a period of a single month did not depress the fecundity or fecundability of 50 rhesus monkeys as compared to 60 untreated monkeys in a timed breeding colony. The birth rates, seasonality of births, interbirth intervals, and waiting time to the next pregnancy were not significantly different before treatment, after treatment, or among the untreated. The stillbirth rate was not increased after treatment.
