If people could save up for the IVF required, just don't see who else's business is it if they have a boy or a girl baby, really?
It seems U that we are not legally allowed to try for this in Britain. Clearly, we'd not all choose boys. See this mother of five sons in the Indy today: www.independent.co.uk/news/science/ban-on-sex-selection-of-ivf-embryos-is-not-justified-says-ethicist-8683940.html
It is allowed in US to do this, and you don't hear of a population imbalance over there. Just what seems like an incannily high proportion of celebrities who have twins, one of each!
I do get the issues about things being very different in other countries where there can be a cultural pressure to have sons of course. And i'm only talking about methods used before pregnancy begins. And obviously this would have to be genuinely freely chosen. Just feel that as the majority in the UK doesn't share any particular preference, why not let the people who do really mind, have the choice?
