People who donate eggs and sperm for use in IVF and other fertility treatments could receive more compensation.
The Human Fertilisation and Embryology Authority (HFEA) is currently discussing increasing the levels of compensation and is due to launch a full public consultation.
A spokesman from the HFEA suggested that the shortage of available sperm and eggs is one reason why people have fertility treatment overseas.
Women currently receive around £250 for donating their eggs, but it is hoped that increasing this will encourage more people to offer their eggs.
The HFEA representative warned that there are risks involved for IVF patients.
"Multiple births are the single biggest risk of IVF for both mother and babies," he said.
"We are working with professional bodies and patient groups to promote the birth of a single healthy baby as the best outcome of fertility treatment."
The HFEA is currently researching the issues involved before launching the consultation paper.
