In the last 20-30 years an increasing number of studies on lesbian parents and the development of their children has been published. PubMed/Medline was used to identify studies for inclusion in this assignment on lesbian families and the focus was review articles. There is a variety of ways of becoming a lesbian mother, and several lesbian couples have began to visit fertility clinics requesting donor insemination. The concern of the general population was that children growing up in lesbian families, and thus deprived of a father figure, had a tendency to develop abnormal sexual identity, atypical gender behavior and sexual orientation. Due to stigma of homosexuality in the society, one believed that their children were more likely to get bullied and have difficulties attaining friendships, which could lead to a higher incidence of depression and anxiety. Evidence suggest that lesbian mothers and their children are doing well, and their families are very much alike heterosexual families. The children do not seem to have more mental illnesses or gender disturbances than other children. They do not report a higher number of bullying episodes, and have several healthy social relationships. Still, lesbian women were not allowed artificial fertilisation in Norway until 01.01.09. The debate prior to the Norwegian Parliament’s resolution to give lesbian women access to fertility treatment, was characterised by arguments of moral and subjective opinions regarding a child’s best interest. This assignment focuses on the reliability of the research and whether the arguments are up to standard.
