Klinefelter Syndrome (KS): NICHD Research Information

The NICHD, part of the NIH within the U.S. Department of Health and Human Services, has supported research on the many facets of Klinefelter syndrome (KS) and its symptoms to improve the health of males with this condition.

NICHD-supported research is currently exploring the causes of chromosomal disorders, how symptoms such as language difficulties and low testosterone develop, and treatments to prevent or counteract KS symptoms, including infertility.
