Estrogen plays an important part in the ovulation process. The pituitary gland discharges hormones which lead in releasing of an egg from its follicle during the menstrual cycle. The estrogen is produced during follicle development. It causes the uterine lining to thicken. Remember that the thickening of uterine lining ensures that uterus becomes receptive to progesterone, another hormone. This new hormone nourishes fertilize egg which develops into fetus. When there is no fertilization, estrogen and progesterone levels fall. As a result, the uterus lining breaks down and it leads to menstruation.
