Progesterone
Additional Information
Progesterone, a C21 steroid, is one of the female sex
hormones. In conjunction with estrogens, progesterone
regulates the female accessory organs during the menstrual
cycle. It also functions in preparing the uterus for the
implantation of blastocysts and in maintaining
pregnancy. Progesterone is produced by the corpus luteum in
nonpregnant females, whereas the placenta becomes the primary
source during pregnancy.
Since progesterone is an obligatory precursor of corticosteroids and androgens, the adrenal glands and testes are minor sources of progesterone in the bloodstream. Blood progesterone concentration is often used to ascertain if ovulation did occur in a menstrual cycle. Elevated progesterone levels may be indicative of adrenal or testicular tumors.
