Estrogen and progesterone are both necessary for the growth of blood vessels in the endometrium. Estrogen prepares the uterine lining for implantation of a fertilized egg and stimulates the growth of blood vessels, while progesterone helps to maintain the uterine lining and further supports blood vessel growth. FSH and LH are involved in regulating the menstrual cycle, but they do not directly affect blood vessel growth in the endometrium.
