[/INST] Hi, Thanks for posting in Chat Doctor. I understand your concern. Masturbation is a healthy and normal physiological phenomenon. Doing it regularly would help in healthier sperm production as well as decreases the mental stress. It doesn't cause any harm to the body like physical weakness, decreasing sexual performance or reducing fertility. Keep your mind clean regarding this and take necessary medications for your underlying disease. Eat healthy food, exercise regularly and stay healthy. Hope the information provided would be helpful. All the best.   </s>
