A couple's sexual orientation determines whether or not they prefer to adopt a boy or a girl. Gay men are more likely to have a gender preference for their adopted child whereas heterosexual men are the least likely. What's more, couples in heterosexual relationships are more likely to prefer girls than people in same-gender relationships, according to Dr. Abbie Goldberg from Clark University in the US. These couples also have very different reasons for their preferences, depending on their sexuality. These findings1, from the first study to compare the child gender preferences of prospective adoptive parents according to their sexuality, are published online in Springer's journal Sex Roles.
