where does progestrone and estrogen initially produced

1 answer

Progesterone and estrogen are initially produced in the ovaries of females. Progesterone is primarily produced by the corpus luteum, which forms in the ovary after the release of an egg during ovulation. Estrogen is produced by the granulosa cells in the ovarian follicles. Additionally, small amounts of progesterone are also produced by the adrenal glands in both males and females.
