An Accurate Way to Predict Miscarriage

Miscarriages occur more often than you think.

For younger women under age 34, about 10% of all pregnancies result in miscarriage.

In women age 45 and up, 50-60% of pregnancies are lost.

If you have had 3 or more consecutive miscarriages, it’s likely there’s a medical or genetic cause.

Now British fertility researchers say they have a way to predict if a pregnancy will end in a miscarriage.

These 6 factors have the greatest impact on miscarriage risk, they say:

History of subfertility

Levels of progesterone

Levels of the pregnancy hormone human chorionic gonadotrophin (hCG)

Fetus length

Extent of bleeding

Baby’s gestational age

The British researchers combined two factors — bleeding and hCG levels — to create a Pregnancy Viability Index (PVI), they reported this week at the European Society for Human Reproduction in Stockholm.

The PVI was able to predict accurately the pregnancy outcome in 94% of women who had ongoing pregnancies, and also predicted the outcome in 77% of women whose pregnancy ended in miscarriage, said lead author Kaltum Adam of Britain’s St Mary’s Hospital in Manchester, England.

“This research has, for the first time, offered us a robust tool to begin to attempt to rescue pregnancies threatening to miscarry when currently all we can do is fold our hands and hope for the best,” Adams told Reuters.

This new tool will allow doctors to focus on risky pregnancies that are likely to go on to miscarry.

It will also help women who are not at high risk to avoid unnecessary treatment, such as repeat blood tests and ultrasound scans during pregnancy, hospital admissions for bed rest, sexual abstinence, low dose aspirin, and progesterone supplementation.

If you have had more than 2 miscarriages, fertility experts recommend that you undergo a recurrent pregnancy loss evaluation.

Miscarriages can be caused by medical conditions, endocrine or anatomic problems, as well as by genetic defects or environmental factors.
