Excessive masturbation, what is masturbation? What we are looking at or what we are talking about is seminal discharge. Now, what is critical in the semen to create a baby. The critical factor which creates the baby is not only the moving sperm and the shape of the sperm, it is the internal DNA of the sperm. So by repeatedly masturbating, we are not allowing sperm to be produced in a normal timely fashion. It is like asking somebody to stich a cloth which normally is done in 4 hours, I want it in half an hour. So what will happen? At the end of the day he will do the job. The body will still produce, but it will produce deformed defective ones. So your chances of conception decreases as you hasten the process. So body has a capacity to produce and that is intrinsic. So two things will happen, one if we excessively masturbate, what is excessive masturbation, two three times a day is harmful. It can cause shrinkage of the penis. It can cause injury to the penis, it can cause production defects in the sperm. Similarly the other way to look at it is during sexual activity in a married couple, what is ideal to have a baby? It is not necessary to have daily sexual activity two three times and tire yourself out because the sperm quality will be not good. So the recommendation is alternate days sexual activity is good enough to have a baby. Infact the sperm quality is far better on an alternate day than even on a daily day.
