Hormonal changes during pregnancy are crucial for maintaining the pregnancy and supporting fetal development. Key hormones involved include:
Human Chorionic Gonadotropin (hCG): Produced by the placenta, it supports the corpus luteum and its production of progesterone. Progesterone: Maintains the uterine lining and prevents contractions. Estrogen: Promotes the growth of the uterus and improves blood flow to the placenta. Relaxin: Helps relax the ligaments in the pelvis and softens the cervix in preparation for childbirth.
