Homosexuality And Bone Lengths In Arms, Legs, and Hands
This article is part of a series,
Written on the Body
, exploring the correlations between our body structures and sexual attraction.

Monkeys climb trees.
People attracted to men (hetero women and gay men) tend to have less long bone growth in their arms, legs and hands, than people attracted to women (hetero men and lesbians).
The theory is that those with longer arm, leg, and hand bones had more exposure to androgens in the womb, and those with shorter bones had less.
Summary:
- Gay Men: Shorter leg, arm, and hand bones in proportion to height indicates lower exposure to male hormones in the womb.
- Lesbians: Longer leg, arm, and hand bones in proportion to height indicates higher exposure to male hormones in the womb.
