Abstract

Klinefelter syndrome is the most common genetic form of male hypogonadism, but the phenotype becomes evident only after puberty. It is characterized by infertility, small testes, sparse body and facial hair, increased body weight, gynecomastia, increased LH and FSH, and a low level of testosterone. Early recognition and treatment of Klinefelter syndrome can significantly improve the patient's quality of life and prevent serious consequences. Here, we report an infertile man with a rare variant of Klinefelter syndrome with a 47, XY, i(X)(q10) karyotype.
