Researchers from Colorado claim the screening treatment could boost a 42-year-old's odds of having a baby from 13 per cent to 60 per cent.
It works by picking only the embryos most likely to create a healthy foetus, slashing the odds of miscarriage, the Daily Mail reported.
The treatment also involves the embryos being frozen for at least a month after In vitro fertilisation (IVF) to allow the woman's reproductive organs to return to normal.
Scientists believe that the powerful fertility-boosting drugs given during IVF can harm the embryo if it is put into the womb too soon.
A woman aged 40 to 42 typically has a low chance of becoming pregnant with IVF and is unlikely to conceive naturally.
Patients will have to pay 2,000 pounds for the test, on top of a cycle of IVF costing 3,000 pounds to 4,000 pounds a course. The process has already been used on 1,200 women in the US.
The US scientists claim their procedure is the most advanced of several being developed to boost pregnancy odds, and is the only one to have been through rigorous trials that have all shown the same high success rates.
Called comprehensive chromosome screening with vitrification, it involves taking a few cells from a blastocyst
