Does masturbation causes infertility in men?

is doing masturbation regularly & more than twice a day leads to infertility in men?

Masturbation, or self-stimulation of the genitals for pleasure, is not a dangerous or bad activity for men or women. In fact, it is quite normal. It cannot cause any health problems-- even though there are many myths that warn of dangers. Masturbation does not cause fertility changes in men or women, such as decreased sperm or egg counts.

There is no numerical safety limit to how many times a day one can or should masturbate. The only time a person should be concerned is if his or her masturbation is so frequent that it significantly interferes with other aspects of the individual's life. For example, if a young man stops socializing because all he wants to do is masturbate, he may become socially withdrawn which creates its own problems. Otherwise, pleasuring oneself is safe and enjoyable.

not in usal but excess may cause it
No. In fact it gears up your sperm production so when you have sex you will be shooting healthier younger tadpoles.
Absolutely not. The testicles produce millions of sperm cells every day, you cannot 'run out'.
poor sexual health.do it once a week.it will be fine!
I seriously doubt it. It makes men hornier.
Not at all, but spending time on the internet instead of having sex can lead to not having kids. :)
