A synthetic organ - made out of the woman’s own tissue - could be transplanted into a female left infertile due to medical treatment. She could then go on to produce eggs naturally.
The breakthrough technique is being developed to help women and girls who face chemotherapy for cancer treatment.
Chemotherapy drugs can render a woman infertile as they can destroy ovaries. Young girls who have not undergone puberty can be rendered sterile before their ovaries can even produce eggs.
One approach to prevent this is to freeze ovarian tissue - which produces eggs - ahead of chemo treatment and replace it afterwards. But this has a risk in cancer patients, as they risk being re-exposed to cancerous cells harboured in the removed ovarian tissue.
The new technique prevents this by stripping out all of the patients’ potentially cancerous cells from the ovarian tissue, leaving just a “scaffold” - a framework of protein which no longer contains any cells, removing the chance cancer could still be lurking. The framework provides an environment for the patient’s ovarian early-stage follicles - which can go on to generate hundreds of eggs - to grow. It can then be grafted into the patient’s body and go on to allow a woman to produce eggs naturally each month.
The experiments will be unveiled by Dr Susanne Pors from the Rigshospitalet Laboratory of Reproductive Biology in Copenhagen at the European Society for Human Reproduction and Embryology conference in Barcelona.
Successful trials in humans are expected to be carried out within five years.Daily Mail
