Progesterone is a steroid hormone secreted primarily by the ovaries (female-only endocrine glands in the human body).

It is one of a group of steroid hormones that control female sexual development and processes.

Although progesterone is synthesized mainly by the corpus luteum of the ovaries, some small quantities of progesterone are also produced by the adrenal cortex, the testes, and the placenta.

The actions of the hormone progesterone in women include:

  • Preparing the inner lining (endometrium) of the uterus for pregnancy;
  • Maintaining the uterus after fertilization and then throughout the pregnancy;
  • Preventing further release of eggs from the ovaries during pregnancy.
