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
Detailed Solution
During pregnancy the placenta secretes human chorionic gonadotropin (hCG).
hCG maintains the corpus luteum and stimulates the synthesis of estrogen and progesterone.
High estrogen and progesterone suppress FSH and LH by negative feedback, so their levels are low.
