[Sex selection as done by the Infertility Clinic, Universitas Hospital, Bloemfontein].

: The possibility of selecting a child of a specific sex even before conception has taken place, is regarded as far-fetched. Due to the increasing demand for sex selection, a programme with this aim was established in Bloemfontein. Couples with two or more children of the same sex who wanted a child of the opposite sex were used as a study group. Due to a lack of interest in children of the female sex, selection was aimed mainly at boys. By meticulous control of ovulation and the time of insemination, selection of sex before fertilisation was attempted. A success rate of 100% was achieved in 8 consecutive cases.
