Question

In a normal pregnant woman, the amount of total gonadotropin activity was assessed. The result expected was

• A. High level of circulating FSH and LH in the uterus to stimulate implantation of the embryo.
• B. High level of circulating hCG to stimulate endometrial thickening.
• C. High level of FSH and LH in uterus to stimulate endometrial thickening.
• D. High level of circulating hCG to stimulate estrogen and progesterone synthesis.

Answer 1

Answer: (B), (D)

High level of circulating hCG to stimulate endometrial thickening.
High level of circulating hCG to stimulate estrogen and progesterone synthesis.

After implantation of blastocyst (pregnancy), the placenta produces the hormone hCG (human chorionic gonadotropin) hCG promotes the maintenance of the corpus luteum to secrete the hormone progesterone and estrogen. High levels of hCG stimulates endometrial thickening also.
