- ... insertions remain risky, but if the glitches can be ironed out the technique could be used to eradicate genetic diseases” (Fackleman 356). Gene therapy also aides in infertility in men. At the University of Pennsylvania School of Veterinary Medicine, researchers have transferred germ cells from virile mice to testes of infertile mice.
