NOT DIRECTLY: In general, an absent vas deferens means that the kidney on that side also didn't develop. Obviously, a person has to have at least one vas and one kidney. It can be difficult to feel the vas on exam but that doesn't mean you don't have them. No imaging study is available to confirm the presence of the vasa. Absent sperm (azospermia) has nothing to do with absent vasa. ...Read more

Not vas deferens: You can't feel the vas deferens as it is a small diameter tube. You may be feeling the epididymis which lies next to the testicle and can vary somewhat in size from one side to the other. Lastly, dilated veins in the scrotum, benign and called a varicocele, can produce a palpable abnormality that varies in size depending on position. All of these are benign. ...Read more
