A unique case of growth hormone and human chorionic gonadotropin treatment in a 45,X male with Y: autosome translocation and literature review.

Maleness associated with a 45,X karyotype is a rare condition in childhood. It is usually diagnosed in adult age because of infertility. We report a unique case of an unbalanced translocation t(Y;21) in a 14-year-old boy with 45,X karyotype referred because of short stature, thin habitus and puberty delay. Hormone analysis showed low serum levels of basal testosterone, insulin-like growth factor (IGF-I) and gonadotrophins. Diagnosis of GH deficiency and puberty delay were made. He was treated with human chorionic gonadotropin (hCG) and GH therapy, respectively, for 6 and 24 months.
