Brief Answer:
Over masturbation does not cause impotency

Detailed Answer:
Hello

My name is Dr Muhammad Ali Rauf & i will look into your problem.

I have gone through your query and would try to help you in the best possible way. Over masturbation does not cause impotency until or unless there is some other underlying cause going. Impotency needs first to be evaluated. I would suggest you to visit hospital and get an appointment with a urologist or medical specialist. Both can help you in this case. Treatment depends upon finding the cause. If there is some disease which is preventing the formation of sperms then medication is given for it or surgical treatment(depends upon the disease). Similarly if there is erection problem then treatment is advised accordingly.


Suggestion:
Visit hospital and get an appointment for medical specialist. He will perform some investigations like Ultrasound scrotum and serum hormone levels (testosterone). They will help to reach the definitive diagnosis.

Hope I have answered your query. If you have any further questions I will be happy to help if not then don't forget to close the discussion and rate it.
Wishing you good health !!
