Doctors may be able to predict which women are at high risk of miscarriage by measuring their hormones, say researchers.

Women likely to miscarry tend to have lower blood levels of hormones produced by the placenta, scientists at University College London found.



In the future, it might be possible to correct the cause of these imbalances to prevent miscarriage, experts hope.



Recurrent miscarriage – three or more in a row – affects one in 100 women.



Doctors had previously noted that levels of a certain hormone, called inhibin A, were lower in failed IVF pregnancies than in successful IVF pregnancies.



Professor Eric Jauniaux and his team, with funding from the Wellcome Trust, set out to investigate whether this hormone and others produced by the placenta might be useful markers of early pregnancy loss.
