The importance of progesterone in the maintenance of mammalian pregnancy is well

initiation of parturition in most mammalian species, including primates5, 7, 8, 12–14, 19, 20,

Progestogen (a term that, like progestin, includes both ‘natural’progesterone and synthetic compounds with progesterone action) 26 administration to prevent spontaneous miscarriage27–39 and preterm birth28, 40–48 has been a subject of investigation for several decades. The use of progesterone in the first trimester of pregnancy to ‘support corpus luteum function’is
