A breakthrough study has revealed babies can be created without a female egg.
University of Bath scientists experimented with mice and discovered embryos could be created from any cell containing their entire chromosome, such as skin cells.
The study produced 30 baby mice by injecting mouse parthenogenotes with sperm. It had a 24 percent success rate, which is an improvement from the 1-2 percent achieved using other cloning methods.
The mice that survived the study were healthy and had normal lifespans.
The study opens up the possibility that infertile women and gay men could produce babies in the future.
Researchers from the University of Regensburg and the Fraunhofer Institute for Toxicology and Experimental Medicine in Germany also participated in the study.
