Q. In a normal pregnant woman, the amount of total gonadotropin activity was assessed. The result expected was :
(a) High level of FSH and LH in uterus to Stimulate endometrical thickening
(b) High level of circulating HCG to stimulate estrogen and progesterone synthesis.
(c) High level of circulating FSH and LH in the uterus to stimulates implantation of the embryo.
(d) High level of circulating HCG to stimulate endometrial thickening
Solution :
Correct option : B Pregnancy can be confirmed by detecting the presence of human chorionic gonadotropin (HCG) in the blood or urine of pregnant women. HCG is a hormone produced by the placenta after implantation. The main function of HCG is to maintain corpus luteum so as to allow the secretion of the hormone progesterone and estrogen. Progesterone enriches the uterus with a thick lining of blood vessels and capillaries so that it can sustain the growing foetus. So, the correct answer is option B.
