• B. High level of FSH and LH faciliate implantation of the embryo
• C. High level of hCG stimulates the synthesize of estrogen and progesterone
• D. High level of hCG stimulates the thickening of endometrium

Answer 1

The correct option is C

High level of hCG stimulates the synthesize of estrogen and progesterone

Human chorionic gonadotropin interacts with the LHCG receptor (Luteinizing hormone chorionic gonadotropin ) of the blastocysts and promotes the maintenance of corpus luteum during the beginning of the pregnancy. Corpus luteum secretes the hormone progesterone during the first trimester. The presence of CG in urine is the indication of pregnancy whose levels increases every 48-72 hours in pregnant women.
