A progesterone test measures the amount of progesterone, mainly produced in the ovaries that is present within the blood. Progesterone has a very important role in pregnancy. After ovulation it will be produced during the second phase of menstruation with its role to prepare the uterus for a fertilised egg ready for implantation. It also has a role to play in preparing the uterus for the actual pregnancy by inhibiting contraction of the muscle of the uterus, as well as preparing the breasts to produce milk.
The levels of progesterone will vary during a woman’s menstruation cycle. At first progesterone levels will be low, increasing once the ovaries have released an egg. If there is a pregnancy then the levels of progesterone will steadily rise to prepare the body to support a foetus. If there is no pregnancy, in other words the egg has not been fertilised, then progesterone levels will fall and a menstrual period will begin.
In a pregnant woman, progesterone levels will be roughly 10 times higher than they are in a woman who is not pregnant. Men also do make progesterone but in the case of a male, it is a very much smaller quantity. Progesterone is made in the ovaries of women, in men it is made in the testes and adrenal glands.
There are other names for this test such as a PGSN, the progesterone blood test and serum progesterone.
