The Study: The ages of onset of body hair growth, deepening of the voice and the appearance of facial hair for 3,199 boys was recorded. In addition, the first use, if any, of tobacco and alcohol were recorded. Early use was defined as use before the onset of a sign of puberty.

The Results: Early alcohol consumption was associated with a delayed onset of signs of puberty, but tobacco use didn’t have the same effect.

Comment: This is the same effect already documented in girls; prepubertal use of alcohol may delay the onset of puberty.
