Abstract
In work presented in PNAS, Gettler and colleagues (1) make an important contribution to our understanding of men's physiology. They find that, in a community-based sample from the Philippines, men with higher testosterone level are more likely to marry than men with lower testosterone; that men who marry and become fathers experience declines in testosterone; and that men who provide more paternal care have lower testosterone levels than fathers who provide less care. This is not the first study that has investigated the social dimensions to male testosterone levels. However, it represents perhaps the most rigorous study of its kind conducted on humans, and clearly demonstrates through a longitudinal design that fatherhood causes testosterone decreases in men. These findings merit attention from several angles.
