Macaques (Macaca mulatta and M. assamensis) which had been maintained on a 12L :12D light cycle for the previous 4 years and had 25-35-day menstrual cycles were randomly assigned to two groups. Those in Group 1 were kept in 12L :12D for 13 months. Those in Group 2 were subjected to three successive 5-month periods of 20L :4D, 4L :20D and 20L :4D. There were no significant differences between the two groups in the frequency, duration and percentage of ovulatory menstrual cycles, suggesting that photoperiod is not the sole regulator of seasonal breeding in these animals.
