Correlations Between Biology and Male Homosexuality Homosexuality, one of many different sexual behaviors exhibited by humanity, has been rejected, persecuted and denied. Are studies that attempt to find causality moral? Is this search for the “why” of homosexuality a continuation of the heterosexist hypothesis according to which heterosexuality is normal and homosexuality abnormal? Is it assumed that homosexuality is an illness and therefore must be treated medically? Is the research currently being carried out heterosexist? Current studies and those carried out in the recent past have shown that there are close links between male homosexuality and biology. By presenting the scientifically significant studies I have encountered, I intend to reduce the ignorance surrounding homosexuality and the behaviors that often accompany it, and show some of the correlations between biology and male homosexuality. Throughout my research into homosexuality, I have been reluctant to go back. and so on, debating the morality of this search for a cause. It seemed that finding a cause for homosexuality was a bit like finding the cause of a disease. Dissatisfied with the association between homosexuality and abnormality, I wondered why scientists were allowed to place homosexuals at such a level. On the one hand, thanks to the biology that supports gay men and women, the fight for equality and basic human rights could be won more quickly. Although science and society have progressed considerably since the days of Nazi Germany, when homosexuality was thought to arise through "seduction and mental traps", criticism of today's scientific curiosity at regard for homosexuality consider that each study and experiment constitutes an effort to strengthen the argument that ...... middle of article ......ce of linkage to micro satellite Markers on the X-Chromosome in a Canadian Study", poster presentation at the International Academy of Sex Research, Provincetown, MA, 1995Slimp, JC, BL Hart and RW Goy, "Heterosexual, autosexual, and social behavior in lesioned adult male rhesus monkeys hypothalamic preoptic-anterior medial", Brain Research 142: 105-122 (1978).
