Question

Quizplus · Accepted Answer

The hormone detected by a pregnancy test is HCG (human chorionic gonadotropin), which is produced by the trophoblast cells of the placenta after implantation of the embryo in the uterus. Option A is incorrect as FSH (follicle-stimulating hormone) is not the hormone detected by a pregnancy test, rather it plays a role in the menstrual cycle and maturation of ovarian follicles. Option B is incorrect as estrogen is not specific to pregnancy, it is present throughout the menstrual cycle and plays a role in reproductive function. Option C is incorrect as progesterone is also not specific to pregnancy, it is involved in the menstrual cycle and maintenance of pregnancy. Option E is incorrect as GnRH (gonadotropin-releasing hormone) is produced by the hypothalamus and regulates the release of FSH and LH (luteinizing hormone) from the pituitary gland.
