I have both low testosterone and spend most of my night urinating. I have read that this is a combination of effects that often has to do with a bad bi lateral varicocele problem (my research). So you probably have the same as me. Varicocele stuffs up the hormones when its bad and testosterone since anything that affects the blood supply running smooth to the testicles affects these elements too
You might also have prostate issues. Pressing on bladder or restricting urinary tract causing the urine flow to be irregular.I dont mean necessarily enlarged prostrate - you can have an infection of that part
Then there is also the possibility of Kidney cancer. That causes frequent urination
The last cause I know of is STD's. But if you havent been playing around with loose women then factor this one out.
In short...if you are like me you will get in and get all bases covered and tested. At the end of that...all I had left to explain my situation was enlarged varicocele. And on Sept 29 I get it operated on. Cant wait.
