The source of estrogen and progesterone in the 1st 10 weeks of gestation is where And the source of them in the last two trimesters is where. So first of all these hormones are important to the development because especially early on they make sure that the uterus is a pleasant environment for the developing embryo. For example, early on the progesterone secretion of this region, make sure that the endometrium stays thick and healthy and doesn't shed off in menstruation. So early on the blastocyst produces human chorionic gonadotropin. So that's the first step. And this HCG hCG causes the corpus luti um to keep producing hormones like progesterone and that means the uterus is still a nice place for the last assist. Later on this role of hormone production is taken over by the placenta. So eventually the corpus lithium degrades and the placenta takes over the hormone production. So the answers here For the initial 10 weeks, it's the corpus lithium and then for the other two trimesters, it's the placenta

Hormones During Pregnancy

What is the role of hormones during pregnancy?

Many hormone levels are affected in the body during pregnancy. Several hormones play major roles during pregnancy. These are:

• Human chorionic gonadotropin hormone (hCG). This hormone is only made during pregnancy. It is made almost exclusively in the placenta. HCG hormone levels found in the mother's blood and urine rise a lot during the first trimester. They may play a part in the nausea and vomiting often linked to pregnancy.

• Human placental lactogen (hPL). This hormone is also known as human chorionic somatomammotropin. It is made by the placenta. It gives nutrition to the fetus. It also stimulates milk glands in the breasts for breastfeeding.

• 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.

• Progesterone. This hormone is made by the ovaries and by the placenta during pregnancy. It stimulates the thickening of the uterine lining for implantation of a fertilized egg.
