The results of a 25-year study, published on June 7 in the journal Pediatrics, concluded that “children raised in lesbian households were psychologically well-adjusted and had fewer behavioral problems than their peers.”

The study followed 78 lesbian couples who conceived through sperm donations and assessed their children’s well-being through a series of questionnaires and interviews.

"This study shows that the 17-year-old adolescents who have been reared by lesbian families are psychologically happy and high functioning," said Dr. Nanette Gartrell, a Williams distinguished scholar at the UCLA School of Law and author of the study.
