Help!

My husband met with his primary care doctor and had some testing done. His testosterone came back low so he referred him to a urologist who specializes in male infertility. He didn't seem to concerned with the low testosterone but after he did an exam he said that his testicles are smaller than normal. He is making him go in for a sperm count/test. He believes it's going to come back very low if any at all. This is so heartbreaking for us and I am hoping that there are some people out there who have some advice or are in a similar situation.
