A test could make in vitro fertilisation (IVF) have a 100 per cent success rate, a new study has revealed.
Researchers at Oxford University found a technique that checks for chromosomal abnormalities in the developing embryo and also looks at two new markers that they believe could potentially lead to failed attempts at becoming pregnant. The new method hopes to be successful in the first cycle of treatment.
The technique has already been recognised with an award from the US Society for Assisted Reproductive Technologies.
Oxford's research team hopes that over time successful pregnancy rates through IVF will reach 100 per cent, a huge increase from the current figure that shows that only 30 per cent of women fall pregnant after a cycle of the treatment.
The scientists believe that chromosomal abnormalities are largely to blame for the low levels of pregnancies from fertility treatment.
Leader of the team Dr Dagan Wells said: "With the new tool we've developed we can count the chromosomes, but we can also look at telomeres, which protect the ends of chromosomes. This might be important."
Potential problems caused by IVF include hot flushes, headaches, restlessness and nausea. More serious side effects such as ovarian hyper-stimulation syndrome can also occur.
