Question

Quizplus · Accepted Answer

Progesterone, estrogen, FSH and LH are all present at times when pregancy has not occured. The placenta, which sustains the developing embryo and later fetus, originates from both maternal and fetal tissues. It produces human chorionic gonadotropin (hCG), which maintains the corpus luteum in the ovary until the placenta begins its own production of progesterone and estrogen. Therefore, hCG is only present when pregancy occurs.
