Quizplus · Accepted Answer

HCG (human chorionic gonadotropin) is the hormone responsible for maintaining the production of progesterone, which is necessary for the maintenance of the pregnancy and the suppression of menstrual bleeding. As a result, if a woman is pregnant, she will not have her period, and HCG levels will be detectable in her urine or blood. FSH (follicle-stimulating hormone), LH (luteinizing hormone), and GnRH (gonadotropin-releasing hormone) are involved in the regulation of the menstrual cycle, but not in the suppression of menstruation during pregnancy.
