Through Adoption

Joint adoption by same-sex couples is permitted in 39 countries. Most countries and territories that allow same-sex marriage (exceptions being Aruba, Curaçao, Ecuador and several Mexican states), as well as several countries and dependent territories that do not (Croatia, Israel and two UK territories of Bermuda and the Cayman Islands) allow for same-sex joint adoption. In some of the countries with marriage, legislation for adoption preceded that for marriage.

According to U.S. census data, 54% of children adopted by gay male couples were boys. Among female couples, 56% were girls.

Adoption is only permitted for same sex married couples in 21 of the 31 Mexican states and Mexico City, despite a Supreme Court ruling that requires states to allow it. Stepchild adoption is permitted for same-sex couples in two countries without same-sex marriage – San Marino and the Czech Republic permit step-child adoption in which the registered partner can adopt the biological and, in some cases, the adopted child of their partner.

Given that constitutions and statutes usually do not address the adoption rights of same-sex couples, judicial decisions often determine whether they can serve as parents either individually or as couples. Opponents of adoption by same-sex couples have argued that same-sex parenting adversely affects children. However, research consistently shows that gay and lesbian parents are as fit and capable as heterosexual parents, and their children are as psychologically healthy and well-adjusted as those reared by heterosexual parents.

Same-sex parents pursuing adoption must also contend with social pressures to conform to heteronormative gender roles. The concept of gender role models is necessitated by the bureaucratic organization of foster care and adoption agencies, particularly in the United States.

Prevalence of adoption

Statistics on the prevalence of adoption by same-sex couples across countries where it is legal are not consistently available.

In 2022, 1 in 6 adoptions in England were by same-sex couples. This number was a 17.4% rise from the previous year.

In the United States, as of 2024, 18% of all LGBTQ people (~2.57 million adults) parent children in their homes, with 14% of same-sex couples (167,000) parenting a minor in their homes. 21% of same-sex couples adopt which is a much higher rate than in different-sex couples (3%).

Quality of life outcomes

A common argument against the legalization of same-sex adoption is that children adopted by same-sex couples would have poorer quality of life outcomes. Overall, scientific research indicates that the children of same-sex couples fare just as well as the children of different-sex couples.

A 2004 study concluded that the sexual orientation of parents did not predict better or poorer "adoptive family functioning, adopted child's behavior, and parent's perceptions of helpfulness from family support networks".

A 2010 study evaluated the outcomes of young adopted children who had been placed in one of 56 lesbian and gay households since infancy. The study found no significant associations between parental sexual orientation and child adjustment.

Research published in 2009 studied 1,384 children with either heterosexual or same-sex adoptive parents and concluded that problematic behavior in children was not dependent on whether they had same-sex or opposite sex parents. The study also found that "adoptive parents are likely to encounter similar challenges in terms of risk factors for child behavioral problems and mitigating factors of such behavior."

A 2016 study of adopted children of same-sex parents showed that they perceive themselves to be more accepting, understanding and compassionate than children of different-sex parents. The children in the study also indicated that they often avoid sharing that their parents are lesbian or gay, and that many experience bullying or teasing.
