Is it normal that my testicles are different sizes and sometimes change size? My right testicle is bigger than my left. The right is about the size of a grape. My left is smaller and probably less than the size of a grape. Two days ago my left testicle felt a bit bigger than my right.
The testicles are the somewhat solid oval shaped organs in your scrotum. It is very common for one testicle to be slightly different in size from the other. However, testicles do not change size, expect as they grow while you are maturing.
More likely you are seeing a difference in the amount of fluid in two sides of the scrotum.
