RE: Older Men's Sperm are worse -- Freeze your sperm whilst young!

Cryonics (and cryopreservation) is one area of emerging technology that holds the power to change the course of human history. Even though I've not heard about freezing of gametes but I've read about an embryo that was frozen and was delivered after about 25 years of being frozen. I've also read about cryogenics finding applications in astro travels. I mean, what can't technology do?
Nice piece there
