Progesterone is a hormone released by the corpus luteum in the ovary. It plays important roles in the menstrual cycle and in maintaining the early stages of pregnancy. It may also be involved in the growth of certain cancers.
While it is correct to say that progesterone is secreted by the ovaries, it's more correct to say that it is a hormone produced by the corpus luteum of the ovaries. The corpus luteum is a structure that develops in an ovary after the egg has been discharged.
