Basie "Once sperm is frozen in liquid nitrogen, its biological activity ceases, meaning it doesn't deteriorate. In fact, the main risk to sperm comes when it's thawed, not while it's frozen. About 50 percent to 70 percent of sperm dies during thawing, but that usually leaves enough behind to allow fertilization, Thornhill said. How long could sperm actually be frozen? No one knows for sure, but experts say it could last indefinitely, perhaps even hundreds of years. There's a problem, however. When the sperm is brought out of suspended animation, the germs inside it come back to life, too. That's why U.S. fertility doctors can't fertilize women with stored sperm until they wait six months to see if the donor has developed a disease such as HIV (news - web sites) or hepatitis."
