17α-Bromoprogesterone (17α-BP) is a progestin which was first described in 1957 and was never marketed.^[1]^[2]^[3]^[4] It is about twice as potent as progesterone in terms of progestogenic activity in animal bioassays.^[1] 17α-BP is a parent compound of haloprogesterone (6α-fluoro-17α-bromoprogesterone) and 6α-methyl-17α-bromoprogesterone.^[5]
