What does estrogen and progesterone hormones prevent from happening?

Estrogen and progesterone hormones play crucial roles in regulating the menstrual cycle and maintaining pregnancy. They help prevent ovulation during the luteal phase of the menstrual cycle and inhibit uterine contractions to sustain pregnancy. Additionally, these hormones work together to prepare the uterine lining for potential implantation of a fertilized egg, preventing menstruation if pregnancy occurs. Overall, they help maintain reproductive health and prevent disruptions in hormonal balance.
