48,XXYY syndrome is a rare form of sex chromosomal aneuploidy. Usually considered as a variant of Klinefelter syndrome because of shared features (azoospermia, tall stature, hypergonadotropic hypogonadism), it is a separate entity because diagnostic is currently made in prepubertal boy with neuro-psychological disorders. We here report the case of a 48,XXYY patient consulting for adult infertility and the indication to perform testicular sperm extraction is discussed.
