Zero sperm count

Kylie • Pregnant with a baby girl after 8 years TTC. 💕
TTC for 4.5 years and after my husband's semen analysis... come to find out he's shooting blanks. Zero sperm count. Going to an infertility specialist next week. We are both absolutely devistated but, happy we FINALLY know the issue. 
Any other ladies' men have a zero sperm count? What do I expect from here with doctors? Treatment?  Just a little anxious and want to get a heads up. 
Thanks so much!
