Test Details & Preparation
Progesterone is a female sex hormone which is very essential to the menstrual cycle and to pregnancy. It is made up by the ovaries and adrenal glands, during menstruation. This occurs in a cyclic fashion and follows the menstrual cycle.
Additionally, during pregnancy the placenta and corpus luteum ‘mass-produce’ progesterone increases. Thus, progesterone levels increase sharply, during pregnancy.
Progesterone facilitates pregnancy by stimulating the uterine-lining to grow. This makes it more receptive to attachment by a fertilized egg. Progesterone also causes an enlargement of the breasts.
Lastly, progesterone saves the growing embryo by decreasing the mother’s immune response.
Males also produce progesterone, but in lesser quantities. Progesterone plays a vital role in the production of sperms and other hormones. A drop in its level could further lead to a variety of disorders in men.
The progesterone test is a blood test which is performed to measure the levels of progesterone in circulation. It is usually used to determine, both the phase of the menstrual cycle and the status of a pregnancy.
