what is the role of human chorionic gonadotropin

Answer 1

Human chorionic gonadotropin (hCG) is a hormone that is produced by the placenta during pregnancy. Its primary role is to support and maintain the production of progesterone by the corpus luteum in the early stages of pregnancy.

Progesterone is necessary for the growth and development of the uterine lining, which provides support for the developing fetus. The corpus luteum, which is formed in the ovary after ovulation, produces progesterone until the placenta takes over this role.

hCG acts on the corpus luteum and stimulates its continued production of progesterone. This ensures that the necessary hormonal environment is maintained and the pregnancy is supported. Without progesterone, the uterine lining may shed, leading to a miscarriage.

hCG also plays a crucial role in pregnancy tests, as its presence in urine or blood is used as an indicator of pregnancy. Levels of hCG increase rapidly during the early weeks of pregnancy and then gradually decrease as the placenta takes over progesterone production.
