Question

List the three hormones produced in women only during pregnancy. What happens to the levels of oestrogen and progesterone during pregnancy?

Accepted Answer

Pregnancy, also known as gestation, is the time during which one or more offspring develops inside the uterus of a woman. There are hormones produced only during pregnancy: human chorionic gonadotropin, human placental lactogen, and relaxin. All these hormones are produced by a temporary organ, which also acts as an endocrine gland called the placenta.

During pregnancy, the levels of oestrogen and progesterone rise up. The increase in the level of these hormones maintains the pregnancy by increasing blood flow to the womb by stimulating the growth of existing blood vessels, stimulating the endometrium to grow and become thickened, etc.
