Predominant sexual orientationOne study carried out in Calgary, Canada, found that 15. 3% of males in the region identified as gay to a point. It also found that about 7% of adult women diagnosed as gay or bisexual. This is easily below the national average for both sexes. Furthermore, the percentage of same-sex interactions is higher among gay men than among heterosexual men. While it is not known what causes the variations in sexual orientation, several experiences have recommended a genetic element. In specific, homosexuality is inherited from a mother's side of the family. Furthermore, gay men are more likely to have gay ancestors on their mother's side than heterosexual men. Studies carried out on prenatal elements have shown that hormones and genes play important roles in sexual orientation. However, there are lots of limitations in our current understanding of the prenatal factors that affect sexual differentiation. For instance, studies on the effect of embryonic endocrine issues on homosexuality have found a very restricted effect size.
