[Hormonal conditioning of vocal changes in male].
Porophonia pubertum is the change of voice following activation of gonads in puberty. The present paper shows disorders of porophonia pubertum in 3 boys. The objective of the paper was to explain the pathogenesis of these disorders. Basing on clinical and genetic tests, a non-physiological, high position of spoken voice typical for the prolonged porophonia pubertum was proved. The genetic test confirmed the male sex. However, hormonic tests proved a significantly increased level of estradiol. We suppose that excessively increased estradiol level in blood serum caused the porophonia pubertum disorders in our patients.
