MADRID, July 2: Scientists in the United States have created hybrid human “she-males”, mixing male and female cells in the same embryo, outraging fertility experts and anti-abortionists.

Dr Norbert Gleicher of the Foundation for Reproductive Medicine in Chicago and a colleague injected male cells into female embryos in research which they believe could lead to better treatments or cures for single gene disorders.

But their work provoked revulsion when they presented it to the annual meeting of the European Society of Human Reproduction and Embryology.

“There are very good reasons why this type of research is generally rejected by the international research community,” Dr Francoise Shenfield of ESHRE said on Wednesday.

“I cannot conceive of any situation in which this particular technique would be acceptable, and if it cannot be applied there is not much use in experimenting with it,” she added.—Reuters
