Hi,
My left testicle seems to have a vein running across it (on the testicle, not loose in the scrotum), which I can see when I hold the skin of the scrotum tight to the testicle. I have also noticed that the tubing on this testicle is opposite to the right one (i.e. epididymis on left testicle is lower, main tube is higher; epididymis on right testicle is higher, main tube is lower). I'm worried that this might be the cause of the vein, and is this vein something to worry about? Many thanks for your help.
