The trophoblastic cells secrete human chorionic gonadotropin hormone which has properties similar to those of lutenizing hormone (LH) of the pituitary gland. It takes over the job of pituitary LH during pregnancy. The hCG maintains the corpus luteum and stimulates it to secrete progesterone.
•The latter maintains the endometrium of the uterus and causes it to grow throughout pregnancy. This also prevents menstruation. Progesterone also causes increased secretion of mucus in the cervix of the uterus that forms a protective plug during pregnancy.

Gonadotropin Activity in a Normal Pregnant Female
Gonadotropins are hormones that stimulate the gonads, which are the testes in males and ovaries in females. During pregnancy, gonadotropins play a crucial role in maintaining the pregnancy and supporting fetal development.
The correct option describing gonadotropin activity in a normal pregnant female is option 'C'.
Explanation:
• During pregnancy, the placenta produces a hormone called human chorionic gonadotropin (hCG).
• hCG is similar in structure to luteinizing hormone (LH), which is produced by the pituitary gland.
• hCG binds to the LH receptors in the ovary and stimulates the corpus luteum to continue producing estrogen and progesterone.
• Estrogen and progesterone help to maintain the pregnancy by thickening the endometrium (lining of the uterus) and preventing contractions of the uterus that could lead to miscarriage.
• In addition, hCG also plays a role in the development of the fetal gonads.
Therefore, the correct option is C, as high levels of hCG stimulate the synthesis of estrogen and progesterone, which help to maintain the pregnancy and support fetal development.
