Antagonists

A gonadotropin-releasing hormone antagonist (GnRH antagonist) is an analogue that blocks the GnRH receptor resulting in an immediate drop in gonadotropin (FSH, LH) secretion. The GnRH antagonist is primarily used in IVF treatments to block natural ovulation.

All GnRH analogues are contraindicated in pregnancy (pregnancy category X).

Famous quotes containing the word antagonists:

    There is a persuasion in the soul of man that he is here for cause, that he was put down in this place by the Creator to do the work for which he inspires him, that thus he is an overmatch for all antagonists that could combine against him.
    Ralph Waldo Emerson (1803–1882)
