why After childbirth, the levels of estrogen and progesterone decrease

1 answer

After childbirth, the levels of estrogen and progesterone decrease due to the removal of the placenta, which is responsible for producing these hormones during pregnancy.

Estrogen and progesterone are essential for maintaining pregnancy, as they support the growth and development of the fetus. These hormones are primarily produced by the ovaries and the placenta during pregnancy.

Once the baby is delivered and the placenta is expelled, there is no longer a need for high levels of estrogen and progesterone. The sudden drop in hormonal levels triggers various physiological changes in the body, including the initiation of lactation and the return of the menstrual cycle.

Additionally, decreased levels of estrogen and progesterone after childbirth can contribute to postpartum symptoms such as mood swings, fatigue, and changes in libido.
