Notes: Progesterone, along with pregnenolone, is the biosynthetic precursor of all other steroid hormones. The main function of progesterone is to prepare the uterine lining for implantation of a fertilized ovum and to maintain pregnancy. Measurement of serum or plasma progesterone levels are used as an index to monitor ovulation and investigate luteal function.
