"August 30, 2005 - Fiona Tasker, Ph.D., has published "Lesbian Mothers, Gay Fathers, and Their Children: A Review" in the Journal of Developmental & Behavioral Pediatrics 26(3):224-240, June 2005.
Dr. Tasker urges pediatricians to consider how to deal effectively with various family forms, which include lesbian, gay, and bisexual parenting arrangements, which may include egg and sperm surrogacy arrangements between gay males and gay females....She admits that many of the current studies are skewed: "The majority of lesbian and gay parents and their children participating in studies have been recruited through advertising. In many contexts, it is still not safe for lesbians and gay men to be publicly 'out' about their sexuality, so a representative sample of lesbian and gay parents and their children probably constitutes an unattainable goal at present."- NARTH.com
