Q. In a normal pregnant woman, the amount of total gonadotropin activity was assessed. The result expected was
A) High level of circulating HCG to stimulate estrogen and progesterone synthesis
B) High level of circulating FSH and LH in the uterus to stimulate implantation of the embryo
C) High level of circulating HCG to stimulate endometrial thickening
D) High levels of FSH and LH in uterus to stimulate endometrial thickening
Explanation
[Solution from source] During pregnancy the placenta secretes large amounts of hCG, which maintains the corpus luteum so that it keeps secreting oestrogen and progesterone. FSH and LH are suppressed in pregnancy and in any case act on the ovary, not the uterus. Answer (1).
