Özet

Traumatic brain injury (TBI) is a frequent health problem and increased prevalence of neurendocrine dysfunction in patients with TBI has been reported. Sports injuries and particularly boxing may result in pituitary dysfunction. However, transient hypogonadotropic hypogonadism after an acute head trauma due to boxing and/or kickboxing has not been defined yet. We describe the case of a 20-yr-old male amateur kickboxer who was admitted to hospital complaining of decreased libido and impotence 2 weeks after an intensive bout. Basal hormone levels were compatible with mild hyperprolactinemia and hypogonaclotpopic hypogonadism. GH axis was evaluated by GHRH+GHRP-6 test and peak GH level was within normal reference range. Three months later his complaints improved and abnormalities in basal hormone levels normalized. He was also re-evaluated 9 months after the first evaluation; basal hormone levels were within normal ranges and he had no complaints. In conclusion acute head trauma due to kickboxing may cause transient gonadotropin deficiency. Therefore, screening the pituitary functions of sportsmen dealing with combative sports is crucial.
