Pregnant with low sperm concentration?

Rachael

Has anyone gotten pregnant with a partner who has a low sperm concentration? My hubby has a varicocele and I know he has a low concentration. I just want to know if anyone else managed to conceive despite this. With diet and lifestyle changes his concentration moved up to 18 mil per mL, a nice increase from where it was a few months back at 15, but still on the low end and we don’t know what his motility is yet.
