'Designer sperm' inserts custom genes into offspring

The "new genetics" promises to change faulty genes of future generations by introducing new, functioning genes using "designer sperm." Research shows that introducing genetic material via a viral vector into mouse sperm leads to the presence and activity of the genetic material in the embryos. These genes are inherited and functioning through three generations of the mice tested, and the discovery could break new ground in genetic medicine.http://feeds.sciencedaily.com/~r/sciencedaily/~3/_...
