Boar and the lonely testicle

I recently bought a boar about a month ago. In my excitement and because I was thrown a curve I hastily brought the boar home and continued to raise it unaware that he had only one testicle.
I just thought it hadn't dropped. Well it seems that indeed he has only one testicle. Do you think he will still breed my two gilts or should I swap him out?
Obviously genetics play a role, but breeds and genetics have also been over emphasized and turned into a market. He has a brother(the pig) that I can swap out(free) but its an hour away. I like my boar and his demeanor, but I don't want emotion to guide me and i want to do what is best to kick start my herd. Any thoughts, or should I play it safe and switch them? Thanks

I have seen the second drop on occasion. Even with just one they are, generally, fertile. It could be a non-genetic congenital defect in which case it is not a big deal. Or it could be a genetic fault in which case I would not want to breed him. You won't know except by breeding several generations to get some data. If you have another better boar I would eat this uni-ball boar rather than breeding him. If you don't have another, go ahead and breed him.
