progestational agent
any of a group of hormones secreted by the corpus luteum and placenta and in small amounts by the adrenal cortex, including progesterone; they induce the formation of a secretory endometrium.

Called also gestagen, progestagen, progestin, progestogen, and progestational hormone.
