Question

Quizplus · Accepted Answer

hCG (human chorionic gonadotropin) is a hormone that is only produced upon a successful fertilization. It is produced by cells that form the placenta and its presence can be detected in a woman's blood or urine as early as 10 days after fertilization. Its presence is an indication of pregnancy. Estrogen and progesterone are hormones involved in the menstrual cycle and can be present whether or not fertilization has occurred. FSH (follicle-stimulating hormone) and LH (luteinizing hormone) are involved in the regulation of the menstrual cycle but are not present only upon successful fertilization.
