How do hormonal changes affect pregnancy histology?
Hormonal changes during pregnancy significantly impact histology. Increased levels of estrogen and progesterone stimulate the growth and vascularization of the endometrium. Progesterone, in particular, is crucial for maintaining the decidua. Additionally, hormones such as human chorionic gonadotropin (hCG) support the corpus luteum, which secretes progesterone in the early stages of pregnancy.
