The pattern of Islamic fasting differs from other forms of fasting, therefore its effect on health also differs. This research studies the effect of Islamic fasting on gonadotropin hormones around the time of the ovulatory cycle and ovulation. This self-controlled study was performed on 24 adult females. Blood sampling was performed during Ramadan and two months later to determine the levels of follicle stimulating hormone (FSH), luteinizing hormone (LH), estrogen and progesterone. Ultrasonography was done in order to detect ovulation and the results were compared. The mean values of FSH, LH and estrogen during the 14th day of menstruation were comparable with non-fasting values. There was no significant difference in ovulation. Islamic fasting causes neither significant variation in hormone secretion around ovulation nor does it influence the occurrence of ovulation.
