To answer your questions:
1) If there is a specific disease leading to the decreased sperm count, then surgery may be helpful in remedying this problem. For instance, varicoceles can sometimes decrease sperm counts, and surgery to correct this issue can lead to fertility in 60 percent of cases.
2) Again, tough to say without knowing why the testicle is smaller. The best way of determining if this is an issue would be to do the sperm count (as you did) as well as measuring the testosterone level.
3) I am unaware of scrotal calcification being connected to cancer. Things like prior infection or testicular trauma can lead to testicular scarring and calcification.
If your present urologist isn't giving you satisfactory answers, you can always consider another urological opinion.
Followup with your personal physician is essential.
