contragestive

adjective Referring to an agent or action which prevents gestation—e.g., by preventing implantation of a fertilised egg.

noun An agent (technically an abortifacient—e.g., RU-486) which blocks progesterone receptors in the endometrium. Without progesterone, the uterus cannot sustain pregnancy, precluding successful gestation.
