The first successful human womb transplant could take place within two years, British scientists have said.
London-based experts say they have worked out how to transplant a womb with a regular blood supply so it will last long enough to carry a pregnancy.
Research involving donor rabbits was presented at a US fertility conference.
The charity Uterine Transplant UK is seeking funding of £250,000 after being denied grants by several medical research bodies.
A breakthrough could offer an alternative to surrogacy or adoption for women whose own wombs have been damaged by diseases such as cervical cancer.
Up to 200 women in the UK are said to use surrogate mothers each year.
In the latest research conducted at the Royal Veterinary College in London, five rabbits were given a womb using a technique which connected major blood vessels, including the aorta.
Two of the rabbits lived to 10 months, with examinations after death indicating the transplants had been a success.
