IVF policy change leads to fewer multiple pregnancies
Your support helps us to tell the story
From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
Your support makes all the difference.One of the biggest risks of in vitro fertilisation (IVF) has fallen sharply after intervention by the regulator to make the process safer. The proportion of younger women having twin or triplet pregnancies following IVF has declined from almost one in three in 2008 to less than one in four in 2010.
Multiple pregnancies are riskier than singleton pregnancies, with a higher incidence of miscarriage and prematurity – one in five women will lose at least one foetus. The death rate in the first month of life rises from 3 per 1,000 for singletons to 19 per 1,000 for twins and triplets.
But they are common in IVF because of the practice of replacing at least two embryos in the womb – and sometimes, in foreign clinics, many more – in the hope that one will take.
Since January 2009, the Human Fertilisation and Embryology Authority (HFEA) has promoted a policy of replacing a single embryo in the womb, which has reduced the multiple birthrate.
