Progesterone

C21 progestogen secreted by corpus luteum via CYP11A1/3β-HSD; prepares endometrium for implantation and maintains pregnancy; metabolized to allopregnanolone (GABA-A PAM); PR antagonism by mifepristone induces abortion; deficiency causes luteal phase dysfunction.

Also known as: P4, progesterone, progestogen, progestin, allopregnanolone, THPROG, PR, progesterone receptor, corpus luteum hormone, luteal hormone
