fertility specialist

My husband and I went to see a fertility specialist yesterday and we were sadly told that it's unlikely that we will ever be able to conceive naturally :-( 
My husbands sperm has a low mobility. Has anyone else been told this and still got pregnant?
We have been told that ICSI <a href="https://glowing.com/glow-fertility-program">IVF</a> is only real hope of having a baby. 
I just feel the whole situation so sad and I can't stop crying... :-(
