- Estrogensearch for term
- The primary female hormone produced mainly by the ovary from puberty to menopause. Estrogen is responsible for the normal growth and differentiation of both the follicle and the egg. It also plays an important role in preparing the endometrial lining where implantation would occur in case of pregnancy. Estrogen also changes the quality and texture of the cervical mucus, making it thinner and more elastic. This allows the normal passage of sperm through the cervix towards the uterus and the tube where it meets the egg.
