Etonogestrel is only found in individuals that have used or taken this drug. It is a molecule used in hormonal contraceptives, most notably the subdermal implant Implanon. [Wikipedia]Etonogestrel binds to the progesterone and estrogen receptors. Target cells include the female reproductive tract, the mammary gland, the hypothalamus, and the pituitary. Once bound to the receptor, progestins like etonogestrel will slow the frequency of release of gonadotropin releasing hormone (GnRH) from the hypothalamus and blunt the pre-ovulatory LH (luteinizing hormone) surge.
