Male infertility?

Renee
If my boyfriend already had 2 kids, then he wouldn't be the reason why I'm not getting pregnant right? So it would most likely be something that's wrong with me? If he already has two
​Kids I'm thinking he wouldn't have a low sperm count... But his kids are ages 7 and 9, his oldest will be 10 in a couple months. He is 30 years old and had his kids when he was 20 and 22. Can 10 years really make a difference you think?
