How Klinefelter’s Syndrome Is Treated

Klinefelter’s Syndrome is usually diagnosed via genetic testing. Once a diagnosis has been confirmed, a patient will be referred to an endocrinologist (hormone specialist). Klinefelter’s Syndrome manifests itself differently in each patient, so a customized treatment plan will be developed to address each patient’s unique symptoms, but some of the most common courses of treatment for Klinefelter’s include:

Testosterone Replacement Therapy

The primary course of treatment for this medical condition is testosterone replacement therapy in order to boost low levels. Ideally, this form of therapy should begin at puberty, and most men will require it for the rest of their lives. Some of the benefits of testosterone therapy include:

  • Increasing personal strength and promoting the development of muscle
  • Increase in pubic, facial, and body hair growth
  • Increase in a patient’s sex drive (libido)
  • Improvement in overall mood and one’s self-esteem
  • Preventing the onset of osteoporosis

However, testosterone replacement therapy does not have an effect on one’s fertility issues, nor does it produce an effect on gynecomastia (the development of breast tissue in males).


Men who have been diagnosed with Klinefelter’s Syndrome often experience abnormal growth of breast tissue, which is referred to as gynecomastia. The most common course of treatment for this symptom is to have plastic surgery to remove the additional tissue.

Treatment for Infertility

Men who have Klinefelter’s and who are considering starting a family must visit a fertility specialist. In recent years, there have been great strides in infertility treatments for men, and the number of men with Klinefelter’s who have successfully fathered children is on the rise.

Tests will be conducted to confirm if a man has viable sperm within his testes. If so, then the sperm will more than likely be extracted and then used for in vitro fertilization or through intra-cytoplasmic sperm injection. ICSI is quite similar to in vitro, and it involves injecting a single sperm into an egg and then embedding the egg directly into the uterus.

However, before following this particular option, it is important for a KS patient to first visit a genetic counselor. The exact risk of a patient with Klinefelter’s fathering a child with the same condition or another chromosomal abnormality is unknown, but current medical research indicates that the chances are rather low.

Additional Treatments for Klinefelter’s

Patients who have Klinefelter’s Syndrome often suffer from speech and language issues and sometimes behavioral issues. Children are often slow to learn how to speak appropriately, slow in learning how to read and write, and have difficulty in processing what they are being told. Both men and children with Klinefelter’s benefit from visiting therapists whom specialise with social skills, coordination, and coping skills. This list of specialists can include physical therapists, occupational therapists, behavioral therapists, family therapists, and mental health counselors or therapists. Many adolescent males and men have also reported an improvement in self-confidence, motor skills, and coordination by participating in physical activities at low key levels, such as tennis, swimming, and karate.
