title: Alcohol dependence in same-sex and opposite-sex twins.
abstract: Males with a female co-twin are more likely to become alcohol-dependent than males with a male co-twin. According to the twin testosterone transfer model, this finding can be interpreted as indirect evidence for a role of prenatal testosterone in alcohol dependence.
