Estradiol (Estrogen) is a female hormone, produced primarily in the ovary. The amount of estrogen produced depends on the phase of the menstrual cycle.
Men also produce estradiol, but only very small amounts.
Shortly before ovulation, estradiol levels surge and then fall immediately after ovulation. They then rise again and remain elevated until 2-3 days before menstruation.
