NEET BIOLOGY

Detailed explanation-1: -Estrogen. This group of hormones helps develop the female sexual traits. It is normally formed in the ovaries. It is also made by the placenta during pregnancy to help maintain a healthy pregnancy.

Detailed explanation-2: -Human chorionic gonadotropin. The most widely studied trophoblast hormone product is hCG. In pregnancy this glycoprotein is critical since it rescues the corpus luteum from involution, and this maintains progesterone secretion by the ovarian granulosa cells.

Detailed explanation-3: -Progesterone is known as the “pregnancy hormone.” Progesterone helps the fertilized egg be implanted in the uterus to establish a pregnancy and help maintain a healthy pregnancy. Women naturally produce progesterone in the ovaries, the placenta, and the adrenal glands during pregnancy.

Detailed explanation-4: -High levels of progesterone are required throughout pregnancy with levels steadily rising until the birth of the baby. During the first few weeks of pregnancy, progesterone produced from the corpus luteum (a temporary endocrine gland of the ovaries) is sufficient to maintain pregnancy.

Detailed explanation-5: -Along with progesterone, estrogen is one of the two main hormones that get the pregnancy party started. Produced by the ovaries and later by the placenta, estrogen helps the uterus grow, maintains uterine lining, regulates other key hormones and triggers the development of baby’s organs.
