Hypertrophy.
resistance/isometric exercise
Hypertrophy
hypertrophy
It damages your muscle. Your body then use the protein from food to repair those muscle, and adapt the muscle to be ready for the next exercise. Resulting in the increase in size.
Exercise help you increase the quantities of Actin and Myosin as well as increase the size of your muscle
Hypertrophy is the increase in muscle size. Transient hypertrophy occurs when fluid accumulation (edema) increases in specific muscles during exercise. It is often called "the pump" because after exercise, blood rushes to the muscles, instantly making them appear larger in size. Chronic hypertrophy occurs when long term resistance training results in the increase of muscle size. The duration for which the increased muscle size remains is dependent on the intensity and frequency of the workouts.
I believe you are asking if EMS (electronic muscle stimulators) increase the size of your penis. First of all, EMS is designed to stimulate muscles and strengthen them. There is no muscle in the penis, and EMS devices are very strong because they are designed for muscle exercise. It would be very rough on your penis. If you did use it, it would not increase the size of your penis although it might feel like electrosex.
When a muscle decreases in size due to a lack of exercise, it is called disuse atrophy.

If you were talking about resistance training, the only measurable difference in size immediately after a strength training session would occur if you deliberately trained in such a way as to experience a "pump" in a muscle group. For a few minutes, that muscle group would be engorged with blood and might be slightly larger than normal. Of course, in the long term proper resistance training will increase your amount of lean muscle mass and that may (at least in men) increase the size of muscles.

The penis is three tubes that become filled with blood, they are not muscle so muscle enhancements won't help increase the size of the penis.
WHen you built up muscles really big. Like body builders. An increase in size of skeletal muscle through an increase in the size of its component cells is called muscular hypertrophy.
