Is it still possible to TTC if my husband's sperm count is low?

I'm worried. We just had our fertility check up yesterday. We've been TTC for a long time now, and since we're both still very young, it's odd that after years, we still can't conceive.

We're still waiting on our results but so far the doctor said my uterus is normal and in good baby housing order. I'll be getting an HSG xray soon to make sure my fallopian tubes aren't block. My period cycle is normal and on time. So doctor said it could be my husband that has a low count especially since its an issue in his family history.

So is it possible? Has anyone out there managed to conceived when your husband has a low sperm count?
