The treatment of a person with Swyer syndrome may depend on the specific characteristics that each person has. Some people need surgery to repair the external genitalia and to create and/or enlarge the vagina. Hormone replacement therapy (HRT) is typically needed from puberty onward and usually includes estrogen and progesterone. In addition to helping with normal development of secondary sexual characteristics, HRT can help prevent bone loss and thinning (osteoporosis) later in life. Abdominal dysgenetic gonads (testes or ovaries with abnormal development) or streak gonads, which are common in people with Swyer syndrome, are at increased risk for gonadal tumors such as gonadoblastoma and should be surgically removed. Although women with Swyer syndrome are infertile, they may become pregnant and carry to term through egg donation.
