Ovulatory Cycle Characteristics in Macaca fascicularis

Menstrual cycle characteristics of the macaque (Macaca fascicularis) were studied in 28 adults over a total of 595 cycles and laparoscopy had no effect on menstrual cycle length ovulation or fertilization.

Abstract

A total of 595 menstrual cycles were studied in 28 adult M. fasicularis over a period of five years. Ovulations, observed laparoscopically in 138 cycles, occurred on the left ovary 62.6% of the time. No significant effect was noted on cycle length relative to the ovulatory status of the previous cycle or the occurrence of ovulation on the same ovary in consecutive cycles. Laparoscopy had no effect on the parameters studied.
