In a normal pregnant woman, the amount of total gonadotropin activity was assessed. The result expected was
1 High level of circulating FSH and LH in the uterus to stimulate implantation of the embryo
2 High level of circulating hCG to stimulate endometrial thickening
3 High levels of FSH and LH in uterus to stimulate endometrial thickening
4 High level of circulating hCG to stimulate estrogen and progesterone synthesis
Explanation:
The placenta acts as an endocrine gland. It secretes progesterone, estrogen and human chorionic gonadotropin (hCG). This hCG allows the corpus luteum to secrete huge amounts of progesterone to sustain the pregnancy.
