- Corticotropin-releasing hormone (CRH), produced by the placenta, plays a role in pregnancy, regulating the secretion of FSH and hGH.
Quiz: Understanding Hormonal Changes in Early Pregnancy Test your knowledge on the hormonal changes that occur during the first few months of pregnancy. Learn about the role of the corpus luteum, placenta, and chorion in secreting progesterone, estrogens, and other hormones crucial for maintaining pregnancy. Explore how these hormones affect the uterine lining, mammary glands, and the suppression of FSH and LH production.
