A controversial fertility treatment is to be reviewed by a clinic regulator.

Debra Sims, of Brodrick Road, Eastbourne, was the first woman in the UK to trial the treatment, called egg-giving.

Her daughter Shannon is now 16 months old.

The method allows women to have expensive IVF treatment at cheaper rates by agreeing to donate their first cycle of eggs to other would-be mothers.

Mrs Sims, 38, and her husband Tony received the treatment free because it was a trial.

Some doctors have criticised the scheme for exploiting less well-off couples who are desperate for a child.

Concerns have also been raised about the necessity and safety of undergoing so many cycles of treatment.

The Human Fertilisation and Embryology Authority (HFEA) is asking clinics to supply details of their procedures for egg-giving.

It aims to establish under which conditions it is suitable and provide guidance to clinics to ensure patients' interests are protected.

Mrs Sims said at the time: "I thought it was great. I couldn't afford IVF and was desperate."
