as a theoretical excersise...

having had natural twins with no family history at a young age, i am aware of the risks associated with a twin pg.

i can see the point of an older couple wanting to increase their chances by having two or more embies transferred, weighing up the associated risk/financial cost of IVF and multiples.

i don't, on principle, agree with designer babies but fully support a couple's decision for genetic testing of embies/gender specification in cases of family-associated genetic issues. (eg hemophilia, CF)

although i personally wouldn't do it, i also support the decision of individuals to do IVF with donor embies.

i absolutely support IVF for single women and same-sex couples who will be financially supporting their kids.


but i do find the notion that an otherwise healthy couple with no infertility issues would choose IVF a bit odd, if not personally insulting.
