Need some uplifting advice!

Me and my husband are both 23 we’ve been together for 7 years and married for 1 year. We have been trying to conceive for 3 years and finally started to go to the dr. I got checked first and everything checked out good for me but we went back for the dr to do a semen analysis he said my husband had zero sperm count. We’re going to see a urologist next month to see what’s going on. I just wanted to see if anyone has had any similar story or problems and if so what was done to help and did it help. I’m very scared that we won’t be able to have kids and I REALLY want kids and want to be able to have my own and carry them on my own. I love my husband so much and always pictured us with our kids that look just like him! Desperately need advice that can calm me down and think positive.
