About steroids

Steroids are used by some athletes and bodybuilders as performance-enhancing drugs. These drugs can help in boosting the levels of testosterone in the body. Testosterone is the hormone that is responsible for increasing muscle strength and muscle mass, boosting stamina, and many other functions.

For some, the impacts are positive while for others it might yield negative results.

Does penile size get affected after using steroids?

Testosterone is naturally produced by the testes, but when the body is getting a dose of testosterone externally, the testes stop producing it. This leads to the reduction or shrinkage in the size of the testes.

The size of the penile might not be affected due to the steroids. It remains the same. It becomes bigger and erects only when the blood flow happens inside the penile arteries, otherwise, it mostly remains in its original size, irrespective of steroid usage.
