Gay, Straight, and the Reason Why

The Science of Sexual Orientation

Second Edition

Simon LeVay

  • Neuroscientist Simon LeVay presents the best current summary of the science of sexual orientation.
  • Marshalls a wealth of evidence that points toward the radical new explanation that sexual orientation results primarily from an interaction between genes, sex hormones, and the developing brain.
  • Illustrates how the same biological processes that influence a broad array of gendered traits are also the guiding factors behind a person's emerging sexuality.
  • Clear, straightforward prose that is accessible to everyone who has questions about what causes a person to grow up gay, straight, or bisexual.

New to this Edition:

  • New chapter, "Beyond Gay and Straight" discusses additional important aspects involved in sexuality and gender, such as transexuality, asexuality, and pedophilia
  • Discusses research findings presented at the University of Lethbridge's 2015 conference "The Puzzle of Sexual Orientation"
  • Includes 170 additional references
