The new code of practice on reproductive technology allows one exception to a recently passed ordinance barring parents from using science to select the gender of their child. Sex selection is permitted to avoid a real risk of gender-specific hereditary diseases such as haemophilia. The Human Reproductive Technology Ordinance, passed last year, already bans gender selection for social reasons. Before the law came into effect, the now-defunct Gender Choice Centre claimed to have produced 100 babies of the gender specified by the parents. Ninety per cent of clients wanted a boy. The Family Planning Association supports gender selection to avoid serious gender-specific illnesses as children suffering such diseases have a reduced quality of life. But the association rejects gender selection for social reasons because it could affect the sex-ratio of the population in the long term and reinforce discrimination.
