Scientists are examining how homosexuality may affect everything from penis sizes to how one navigates new cities, reports the Los Angeles Times. Innate differences between gays and straights rooted in biology could lead researchers to discover the biological origins of sexual orientation.

Recent studies on gay traits have found:

  • Each older brother a man has increases his chances of being gay by 33%.
  • Testosterone levels in the womb may explain why there are more lefties among homosexuals.
  • Gay men’s hair may grow in a different direction.
  • Gay men have longer, thicker penises—or at least they claimed to in one mail-in survey by famed sex researcher Alfred Kinsey.
