In many European countries, national health systems pay for several IVF cycles for eligible couples but it can cost more than $10,000 for those seeking it privately. For many couples, up to three cycles are necessary to create a baby.
She has asked Britain's regulatory agency for fertility treatment for permission to test the simpler technique.
Some said the success rates of the cheaper IVF method would likely be lower than those for regular IVF. The simplified method does not include any extensive screening of embryos or any procedures to inject sperm directly into the eggs.
"You aren't producing as many eggs with this (cheap) method so the numbers will not be as high," said Ian Cooke, an emeritus professor of reproductive medicine at Sheffield University. Cooke also thought training enough health professionals in developing countries might be an issue.
Still, he said the method was promising. Because doctors were planning to use less potent fertility drugs, he said it was fine to cut back on the regular screening and daily tests used in normal IVF regimens.
"From a technical point of view, they have proven it works," he said, adding it was now necessary to test the technique in developing countries.
Patient groups said doctors should offer the cheaper IVF method if it is approved.
"IVF is not a one-size-fits-all process," said Susan Seenan, deputy chief executive of Infertility Network UK. "Patients are being told they need all kinds of expensive procedures and this may be a good time to step back and see if that is really the case."
