The ovarian cycle could not be determined because this period does not occur concurrently with the gestation period, and the asynchronous nature of the reproductive cycle prevents it by analyzing the time series of follicle diameter of non-gravid mature females.

Once an individual becomes pubertal, this sequential pattern of ovarian activity (follicle growth-ovulation-corpus luteum formation) is continually repeated, and is known as the ovarian cycle. Before we consider the details of ovarian cycles, it may be helpful to note that in cases of multiple births more than one follicle reaches the pre-ovulatory stage and ovulates.
