Two cases of Klinefelter's syndrome diagnosed at a sexually transmitted infection clinic

Abstract

Klinefelter's syndrome is an important genetic cause of infertility in males. Two cases are described, which were picked up at the sexually transmitted infection (STI) clinic because of the finding of unusually small testes. Physicians at STI clinics are uniquely placed to detect this condition as they examine the genitalia of thousands of healthy young men each year as part of a sexual health check up. Benefit of early diagnosis and treatment includes improved quality of life and avoidance of serious complications.
