Parenting

Scientific research has been generally consistent in showing that lesbian and gay parents are as fit and capable as heterosexual parents, and their children are as psychologically healthy and well-adjusted as children reared by heterosexual parents. According to scientific literature reviews, there is no evidence to the contrary.

Some research has examined the sexual orientation of children raised by same-sex couples. A 2005 review of studies by Charlotte J. Patterson for the American Psychological Association did not find higher rates of homosexuality among the children of lesbian or gay parents. According to Bailey et al. 2016, available data do not suggest higher rates of non-heterosexuality among children of same-sex couples. However, they state that even given a modest heritability of sexual orientation, it would be expected that biological children of non-heterosexuals would be more likely to have a non-heterosexual orientation due to genes alone. According to a 2011 data, 80% of the children being raised by same-sex couples in the US are their own biological children. In addition, accepting social environments may facilitate the open expression of individuals same-sex attraction. Thus, it is necessary to control for various confounding factors. One study by Bailey et al. found that the sexual orientation of sons raised by gay men was not related to length of time they had lived with their fathers (social theories of homosexuality would predict sons who lived with a gay father the longest would be most likely to be gay). The Bailey et al. review conclude that social environmental influence on male sexual orientation is not well supported, while it remains more plausible for female sexual orientation.
