Trying to conceive

My fiancé and I are trying to have a baby like most of us. We haven't been trying long and I don't think we've been mapping it out as correct as possible but we're praying for a blessing. Don't want to put too much stress on it. Just going with the flow. 
He fears he can't have kids because he's been kicked in the sack a lot. What do you guys think? He does have a ball sack that hangs lower than the other, could he have problems? His worries worry me. I'm praying for a blessing. Send me your blessings and happy thoughts. Even if we have one baby, and that's all I'd be overjoyed 
If u have advise for us let me have it folks! Thank you!
