Progesterone is one of the steroid hormones.



It is secreted by the corpus luteum and by the placenta and is responsible for preparing the body for pregnancy and, if pregnancy occurs, maintaining it until birth.



Corpus luteum



Progesterone secretion by the corpus luteum occurs after ovulation and

continues the preparation of the endometrium for a possible pregnancy

inhibits contraction of the uterus

inhibits development of a new follicle

If pregnancy does not occur, secretion wanes toward the end of the menstrual cycle, and menstruation begins.
