In many cases, infertility is caused by hormonal imbalances that affect ovulation in women. Hormonal therapy replaces or enhances the hormonal stimulation necessary for a couple to become pregnant.
Two hormones, FSH and LH, are released by a woman's pituitary gland to induce normal ovulation. FSH (follicle stimulating hormone) is primary responsible for growth and development of the egg follicles in the ovary, LH (luetenizing hormone) is released in a burst at mid-cycle ("LH Surge") to trigger ovulation (rupture of the follicle and release of the microscopic egg). Depending on your individual needs, you may receive one or more "fertility drugs" to improve FSH and LH functions, to growth one or more egg follicles, to stimulate ovulation.
