He argues that sexual orientation should be understood as an aspect of gender that emerges from the prenatal sexual differentiation of the brain, and criticizes psychoanalytic and behaviorist explanations of sexual orientation. The book received mainly positive reviews, praising it for LeVay's wide-ranging overview of scientific research on sexual orientation.

In , it received the Bullough Book Award for the most distinguished book written for the professional sexological community published in a given year.
