Effects of hormonal changes on the human voice: a review.

The human voice is commonly affected by hormonal changes, both in physiological and pathological conditions. Voice changes were reported in a number of endocrine disorders, and dysphonia may be the initial sign of these disorders. A number of studies documented endocrine-related voice changes utilizing both subjective and objective voice assessment tools. The objective of the present review is to draw the phoniatrician's attention to the wide variety of typical changes, as well as the potential for hormonal imbalances that may affect the voice, in order to identify them promptly and generate proper treatment and referrals.
