PREDISPOSITION TO BE HOMOSEXUAL

Man XY receives a single copy of that variant provided by the X chromosome from the mother. In case of being the least effective binding of testosterone to the androgen receptor or lower sensitivity to androgens, and since the sexual maturation of his brain does need adequate levels of testosterone, would establish the innate predisposition to the homosexual orientation. For this reason homosexuality are greater among men than among women, being the male homosexual orientation more defined and constant during the different epochs of life.
