“Boys with the Klinefelter syndrome may be sub-sufficient in androgen activity and require replacement therapy. That is controversial for the ‘mini’-puberty during the first few months of life. Whether androgen therapy will be helpful to boys between “mini” puberty and adolescence is being studied with the weak androgen, oxandrolone. Replacement starting in mid-puberty is required for most males with KS and important for the developmental of secondary sexual characteristics, and to permit the normal accrual of muscle mass, bone mineral content, adult regional distribution of body fat. Secondary goals of psychosocial development and both positive or negative behavioral effects of testosterone in KS need further study.”
