Normally, one of the ovaries releases a single mature egg every month. Women may experience pain or abdominal discomfort at the time of ovulation and occasionally have some slight vaginal bleeding. The presence or regular periods, premenstrual tension and period pains usually indicate that the menstrual cycles are ovualtory. Eggs are stored in the ovaries in a very immature form. In this state they are not capable of being fertilized by a sperm until they undergo a maturing process which culminated in their release from the ovary at the time of ovulation. Egg maturation & ovulation are stimulated by two hormones and luteinzing hormone. These two hormones must be produced in appropriate amounts through out the monthly cycle for normal ovulation to occur.
