‘Peak twins?’ - Scientists say IVF means more being born now than ever before

With about 1.6 million twins born each year worldwide, the global twinning rate has risen by a third since the 1980s, to 12 per 1,000 deliveries from 9 per 1,000 around 30 years ago, the study found.

More twins are being born now than ever before, largely due to rising use of in vitro fertilisation (IVF) and other assisted reproduction techniques, the first global study of human twinning has found.
