Quadruplets

A multiple pregnancy in which four fetuses develop in the uterus at the same time. Quadruplets are extremely rare in the UK, at around 1 in 700,000 pregnancies, although the incidence is higher in other parts of the world, e.g. West Africa. When IVF treatments were first introduced, with no limit to the number of embryos that could be implanted, the incidence of multiple pregnancies - quadruplets, quintuplets, sextuplets and septuplets - increased but survival rates in these pregnancies were low.
