A woman typically ovulates once per menstrual cycle, which is approximately once a month. Over 40 years of fertility (from age 10 to 50), she would have about 12 cycles per year, totaling around 480 cycles. Considering two pregnancies, which would reduce the number of ovulations, approximately 450 oocytes would mature and be released.
