Parents should have a choice on surplus embryos

STEM cell research is a topic of considerable interest to many members of the National Infertility Support & Information Group (NISIG) — a voluntary, non-profit, multi-denominational body set up in 1996.

Freezing embryos is very beneficial to couples as it reduces the amount of drugs the female has to take to produce eggs (ova). Taking drugs can be fairly tough, and it also holds the risk of ovarian hyperstimulation syndrome.

While undergoing treatment most females produce eight to twelve eggs, and of those, four to eight will fertilise. Many will not be suitable for freezing. Doctors do not create life; they provide a safe place for the gametes to meet.
