A technique utilizing laparoscopy to determine the precise time of ovulation in three species is described. Determination is based on morphological changes that occur 24 to 36 hours before ovulation. This technique, coupled with mating sessions of short‐duration, has been used to produce precisely defined pregnancies; the implications of this technique in reproduction research and teratology are discussed. A comparison of ovulation times in Macaca fascicularis indicates that ovulation normally occurs on day 13 of animals having a cycle length from 25 to 28 days. In animals with a cycle length from 31 to 34 days, ovulation occurred on day 14.8. Evidence presented does not substantiate previous claims for alternation between ovaries in consecutive cycles.
