Many men who have Klinefelter syndrome do not have obvious symptoms. Others have sparse body hair, enlarged breasts, and wide hips. In almost all men the testicles remain small. In some men the penis does not reach adult size. Their voices may not be as deep. They usually cannot father children. But they can have a normal sex life.Some boys with Klinefelter syndrome have language and learning problems.

 

Klinefelter syndrome usually is not diagnosed until the time of puberty. At this point, the boy's testicles fail to grow normally and you may start to notice other symptoms.To find out if your son has Klinefelter syndrome, your doctor will ask questions about his past health, do a physical exam, and order a chromosome test called akaryotype

 

Males with Klinefelter syndrome can be given testosterone, a hormone needed for sexual development. If treatment is started around the age of puberty, it can help boys have more normal body development.Testosterone is given by injection or through a skin patch or gel. The treatment usually continues throughout a man's life but does not help infertility.Speech therapy and educational support can help boys who have language or learning problems.If a man with Klinefelter wants to have children, he may be able to have his sperm collected through testicular sperm extraction (TEST). During TEST, sperm are obtained using a thin needle inserted into the testicle or through a small cut made in the testicle. Normal sperm are identified and then used for in vitro fertilization.
