Introduction
When does ovulation occur?
In women of normal childbearing age, the ovaries release only one egg per month. A woman’s ovulation typically occurs approximately 14 days before the onset of her next menstrual period. For safety, the “fertile window” (ovulation period) is defined as the 10-day interval encompassing the day of ovulation plus the 5 days preceding it and the 4 days following it. All other days—excluding menstruation—are considered the “safe period.”
In women of normal reproductive age, the ovaries release only one egg per month. It takes approximately 14 days for a primordial follicle to develop into a mature follicle and subsequently ovulate—a process involving a series of complex physiological and biochemical reactions.
During this process, specialized cells within the follicle secrete both androgens and estrogens. Estrogens regulate the cyclical changes in the endometrium, thereby establishing the menstrual cycle.
