Testosterone replacement in 49,XXXXY syndrome: andrological, metabolic and neurological aspects

Abstract

In cases of plurimalformative syndrome, cognitive impairment, recurrent infections during growth and, primarily, delayed puberty, it is necessary to ascertain as soon as possible whether the patient is suffering from hypogonadism or metabolic disorders due to genetic causes. In our case, the diagnosis of hypogonadism, and then of 49,XXXXY syndrome, was unfortunately made only at the age of 19 years.The testosterone replacement treatment, even though delayed, induced positive effects on: i) development of the reproductive system, ii) regulation of the metabolic profile and iii) interaction with the social environment and context.However, earlier and timely hormonal replacement treatment could probably have improved the quality of life of this subject and his family.
