Night flow of sperms during sleeping is due to the release of the excessive semen which has been formed in our body. The synthesis of fresh semen takes place all the time. If it is not released normally by sexual activities or by masturbation then it gets released on its own. This is not a medical problem and does not need any treatment. Indulging in sex will improve your problem.  I hope this information has been both informative and helpful for you.  Consult Physician for weakness...
