Well, at the end of the video it explains that after thousands of kicks, his balls are, literally, hard as rock. So if he isn't already fertile before the kick, he probably isn't now.

 

I still don't understand how his balls didn't suffer any damage. Testicles are soft tissue...the strengthening of the pelvic bone is irrelevant.

 

I thought the same thing as you and watched over a few times. Only explanation is that he doesn't feel the pain as much and that they got "toughened". We get fancy graphics for the bones getting stronger but none for the balls.

 

Or that all the nerves in and around his testicles have been destroyed. Either way.

 

I wonder if he can still do the "Act" with those balls.

 

Fuck I hope not.

Besides, what kind of woman would want to screw a guy who got up to these kind of shenanigans. I think the only kind of action he sees in his nether regions is of the shin bone variety.
