Abstract

A hypogonadal male with 48 XXYY Karyotype--a rare Klinefelter's syndrome variant--is presented with review of the literature. Cautious initiation of testosterone replacement therapy to our patient was associated with sexual maturation and, interestingly enough, disappearance of his longstanding aggressive fantasies and behaviors towards females. An explanatory hypothesis is proposed and clues for early detection of the syndrome are suggested.

How strong is the evidence?

Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
