Your ovaries make progesterone after ovulation. The most important role of progesterone is to get your uterus ready so that it can receive, implant, and support a fertilized egg during pregnancy. Progesterone levels are often low during the first stage (follicular stage) of your menstrual cycle. Progesterone is critical for successful ovulation in the ovary and for the multi-faceted role of the oviduct in mammalian reproduction. The role of progesterone (P) in the mechanism of ovulation is controversial at best. The contraceptive application of P was established in rodents in 1936 and with orally absorbed progestogenes was put to human use. There were hints on the proovulatory actions of P administered before the time of ovulation in rats by 1948.
Is progesterone responsible for ovulation?
Progesterone is often called the “pregnancy hormone” because a woman’s body releases it throughout pregnancy. However, it’s not by any means the only hormone involved in the ovulation process.

Do the ovaries contribute to blood plasma levels of progesterone?
At this point, the contribution of the ovaries to the blood plasma levels of progesterone is minor. It is reported that the progesterone produced during the follicular phase is important for subsequent ovulation, but it is after ovulation that progesterone dominates.
What glands produce progesterone?
The adrenal glands and the placenta can also produce progesterone. In the middle of a person’s menstrual cycle, a rise in levels of luteinizing hormone leads to ovulation. Ovulation refers to the release of an egg from one of the two ovaries.
