  4. 4. -The social attitude to Gay and Lesbian. In perspective of religion General opinion
  5. 5. I. Why people become homosexual? 1. Biological and innate factors - Not a new discovery. - Born that way with body function of opposite-sex and having no choice.
  6. 6.  1.1 Gender Identity Disorder (GID) Vocab: embryos – Phôi thai Androgen: hoocmon Andogen  Study of embryology Early embryos all start out as female. At some point in early gestation, if the chromosomes destine the fetus to be male, the embryo is altered by the genetically programmed addition of certain hormones, called androgens. These androgens, especially testosterone, instruct the embryo to develop male characteristics. In their absence, the embryo continues to develop into a female. An "XX" pair of chromosomes will yield a female. an "XY" pair will result in a male.
  7. 7. - If the baby carries "XY" chromosomes and is destined to become a male, testosterone needs to activate the newly forming hypothalamus. - If a mother is stressed during the early stages of pregnancy, she will release an adrenaline related hormone into her shared bloodstream with her unborn baby. This hormone, called Androstendione, is structurally similar to testosterone, the male hormone. Release androstendione ( same to testosteronehormone ) Stress Homosexual embryos
  8. 8. 1.1 Disorder.
  9. 9.  1.3 Twin studies Clip 3 phan - Drs. Michael Bailey and Richard Pillard studied identical and fraternal twins. (Bailey and Pillard, pp. 1089–96) They identified homosexual males who had identical twin brothers and found that 52% of the brothers were also homosexual. Among fraternal twins, they found the ratio to be 22%. They concluded that since identical twins had a higher incidence of mutual homosexuality than fraternal twins, there must be a genetic component in the development of homosexuality. - However, if genetics caused the homosexuality, the correlation between the identical twins (who have exactly the same genes) should have been much higher—even 100%. Since all the twins in this study were raised together, it is impossible to determine whether genetics or the same family environment contributed to the brothers’ homosexuality. If the genes are identical and the brothers are raised in the same family environment, a correlation of only 52% in identical twins shows that other factors are involved.
  10. 10.  1.4 Chromosome studies • In 1993, Dr. Dean Hamer announced that he had found a correlation between DNA markers on the X chromosome (region Xq28) and sexual orientation in a selected group of homosexual men and their relatives over age eighteen. In other words, "it appears that Xq28 contains a gene that contributes to homosexual orientation in males.“ “ Xq28 plays some role in about 5 to 30 percent of gay men. The broad range of these estimates is proof that much more work remains to be done.” Yet, a later study by the University of Western Ontario "found no consistent pattern of DNA similarity on the X chromosome."
  11. 11.  Gender identity disorder (GID) - What is GID? - 75% people being gender identity disorder are homosexuals when come to be adolescents.
  12. 12.  Scientists’ conclusion Studies indicate that ’’ genetic influences plays an partially stimulating role in gays and lesbians’ behaviour’’ They believe that homosexuals can be changeable and improved through their life. There is the fact that, regardless of any biological thread, thousands of people who experience same-sex attractions have made changes in their lives for the better.
  13. 13. 2. Strange sexual experiences, particularly in early childhood. 2.1 Precocious and excessive masturbation. 2.2 Defeat in love again and again 2.3 Sexual abuse. Sexual abuse Psychological wounds Pain from opposite -sex Vocab: - Precocious: having developed particular abilities at a younger age than usual - Masturbation: give yourself sexual pleasure by rubbing your sexual organs
