Genetically modified sperm information


Genetically modified sperm (GM sperm) is sperm that has undergone genetic modification for biomedical purposes, including the elimination of genetic diseases or infertility.[1] Although the procedure has been tested on animals such as fish,[2] pigs,[3] and rabbits,[4] it remains relatively untested on humans.[5] In the case of pigs, the goal of research is to inexpensively produce organs and supplement the shortage of donated human organs.[6] Although GM sperm has the potential to detect and treat genetic diseases, it will likely take many years for successful use in patients.
