Sex selection
Many countries prohibit sex selection. The performing of a treatment procedure or the use of sperm, eggs or embryos with the purpose of producing, or attempting to produce, a child of a particular sex is illegal unless to avoid the risk of genetic transmission of sex-linked diseases. In the UK all licensed centres are forbidden from carrying out such procedures unless for avoidance of sex-linked diseases. However, non-licensed centres may be able to offer sex selection services using methods to separate sperm and intrauterine insemination.
