You should start by asking your urologist what "100% abnormal" means -- what might have caused it, and whether this could be just a temporary problem possibly soon to be fixed by the weight loss. (When guys get a varicocele, for example, which is like a varicose vein in the scrotum, the area is too warm and sperm doesn't make it through, but when the varicocele is repaired, things go back to normal.) Maybe also check with an endocrinologist.
