I am of 22 i got addiction of masturbation . i used to do myself daily once . does this lead to a lack of sperm? any problem occurs in future ?

No problem w sperm: Masturbation will not harm the sperm count or quality, at least at the rate of 1/day. Men with "poor semen quality" can reduce their sperm count with daily ejaculation, so when you are trying for a pregnancy, we usually recommend ejaculation every other day. I again stress that if semen quality good then daily ejaculation will not harm fertility potential. Best wishes.

Unlikely: Addiction can never be good , but the side effect thai mentioned r unlikely to happen.

May be normal: Addiction or dependence is typically thought of as a maladaptive pattern leading to significant impairment or distress. In addition, with addiction, important social, occupational, or recreational activities are typically given up or reduced because of the addiction. Most people eat every day too, but they are not "addicted" to food. Sexual activity is normal and not inherently maladaptive.

You're fine: Most teenaged males enjoy their bodies daily, and i'm sorry that somebody told you this made you an "addict". It keeps you comfortable, helps you learn about your body, and lets you focus on other things you need to be doing. Frequent ejaculation lowers the sperm count only because there's less reabsorption of fluid. Anybody who says it will make you infertile is lying to you. Embrace being male.

No: Don't worry about lack of sperm. Hope you find a good partner as "addiction" to masturbation generally make people feel guilty. Don't worry for your sperm and good luck!
