Recently, Steve’s testicles have grown very large and he has no idea what’s going on. He hasn’t had any surgeries, but about two months ago, his doctor put him on high-blood pressure medication for his Diabetes. Now his legs, feet, and testicles are gaining in size and he’s gained 18 pounds in two months. He’s very worried this could be a sign of something serious.

Dr. Harry Fisch’s Advice:

There are many reasons that men suffer from enlarged testicles but one of the more common reasons is a condition known as hydrocele. This occurs when too much fluid collects around the scrotum and usually happens after a vasectomy.  It can happen if the area gets infected, however, in your case that probably isn’t the cause.

What you have is called dependent edema -- this means that, because of your Diabetes, you could very well suffer from congestive heart failure if this isn't taken care of. Not enough blood is passing through your body, so everything below the belt is becoming swollen. Your heart is not strong enough to pump blood through your kidneys and toxins are building up right now.

Fluid is just sitting at your scrotum because it can’t go anywhere else. This could be a sign of heart failure, and it means you need to go to the emergency room immediately. You need to get a diuretic in order to flush out all the excess water from your system.
