endencies. " It would begin to suggest why male homosexuality is present in most human populations, despite cultural constraints, " says Dennis Landis, a neurologist who studied brain structure at Case Western Reserve University. ( Williams, 1993) A woman by the name of Barbara Grizzuti Harrison criticized LeVay's theories and found several flaws in his experimental studies. First off, she looked at LeVay's sample population. It turned out that LeVay had autopsied 19 homosexual men, 16 men presumed to be heterosexual, and 6 women presumed to be heterosexual. So already we have one flaw, too small a sample size. Flaw number two was that LeVay simply presumed that the 16 males and 6 females were heterosexual. Perhaps they hadn't come out of the closet yet. Or perhaps they were bisexual! Flaw number three being that all of the 19 homosexual men died of AIDS, which infiltrates the central nervous system. How could he be sure that there wasn't some relationship between the disease and the size of the hypothalamus? So you see, differences in brain structure couldn't be proven according to LeVay's studies. More recently, however, scientists have begun to view sexual preferences as hereditary. It is no longer a question of nature vs. nurture. Most homosexual men and women have always had the same sexual orientation. Among gay men, 96% had their " first crush " on another male. Whereas 100% of heterosexual males were first attracted to females. One thing that didn't differ between heterosexuals and homosexuals was the age at which they had their first attractions. Most males had their first attractions around the age of 10. Also, 86% of gay men had their first sexual activity with another male. With heterosexual males, on the other hand, only 73% had their first sexual activity with a female! The age median age for puberty among males, regardless of sexual orientation, is approximately 12 years of age. Although gay men who reached puberty later tended to have fewer sexual partners than men who reached puberty at an early age. Most gay men self - acknowledge that they
