XXY (Klinefelter syndrome)
There's no cure for Klinefelter syndrome, but some of the problems associated with the condition can be treated if necessary.
Possible treatments include:
TRT involves taking medication containing testosterone. It can be taken in the form of gels or tablets in teenagers, or given as gel or injections in adult men.
TRT may be considered once puberty begins and may help with the development of a deep voice, facial and body hair, an increase in muscle mass, reduction in body fat, and improvement in energy. You should see a specialist in children's hormones (a paediatric endocrinologist) at this time.
Long-term treatment during adulthood may also help with several other problems associated with Klinefelter syndrome including osteoporosis, low mood, reduced sex drive, low self-esteem and low energy levels although it can't reverse infertility.
