I've been on for years, and my son was just born... the thing is though, his mom and i are both white, but he came out black, which was weird cause we barely had sex as she was spending the night at her girlfriends house all the time. Must be from all the test I've used over the years tho...
lol j/k
I only have a daughter and she was born before I ever touched juice. I agree with jerseystepup though, I think it's all individual, and needs to be checked as an individual thing. I know a few men who can't conceive and they never touched any type of juice.
