Endocrine findings suggestive of alcohol dependency include which of the following?

• A. Testicular atrophy, gynecomastia, and sexual dysfunction
• B. Hyperthyroidism
• C. Adrenal insufficiency
• D. Elevated prolactin without other signs

Answer: (A)

Chronic alcohol use commonly disrupts the male hormonal balance by affecting the gonadal axis and liver metabolism. This leads to low testosterone from direct testicular toxicity and impaired signaling from the pituitary, which manifests as sexual dysfunction. At the same time, the liver’s ability to metabolize hormones is impaired and estrogen production or aromatization increases, raising estrogen levels relative to testosterone. The result is gynecomastia, since excess estrogen stimulates breast tissue growth. Prolonged alcohol exposure can also cause testicular atrophy from direct gonadal damage, contributing further to reduced testosterone and sexual dysfunction. Collectively, these endocrine changes—testicular atrophy, gynecomastia, and sexual dysfunction—are a recognizable pattern associated with alcohol dependence in men. The other options don’t align with this characteristic constellation: hyperthyroidism and adrenal insufficiency are not typical endocrine consequences of alcohol dependence, and prolactin elevation without other signs is not the classic presentation used to identify alcohol-related hormonal changes.
