It can decrease...: BP can decrease when you pee due to tensing the abdomen or straining--causing the vagus nerve to open some blood vessels wider and drop the heart rate--which can result in a person passing out. Abdominal straining while peeing can also slow blood returning from the veins below the abdomen (in your case, the veins supplying the testicles) resulting in further blood pooling in these veins.
