I had not heard that story. I always thought it was related to Jewish customs. I personally know of one set of parents who attend a church that very specifically teaches boys about the evils related to masturbation in a boys only Bible study class; apprently according to some part of the Bible, a boy is likely to become sterile or have a low sperm count from masterbating. If this is indeed is true, the world's population is singificantly reduced by at least 99.9% of what it would be otherwise.
