Even if we take the research results for granted (which I would not, since this study admittedly contradicts a similar study, and only offers guesses as to what physical mechanism causes masturbation to allegedly be beneficial to health), it's probably (heatlh wise) just a case of stealing from Peter to give to Paul.
Even if there were some health benefits in one area, there are certainly health problems in other areas created by chronic masturbation and sexual fixation. This is besides the fact that "health" should not be narrowly understood as the body, but as the whole person (including their psychological and social well being.) Taking that position, the total benefit of habitual masturbation (which is what the article is recommending, citing men who masturbate five times a week - almost daily) is either nil, or in fact detrimental.
Totally above this, though connected to the psychological ramifications to be sure, is what the moral/ascetic teachings of Christ demand of us, if we wish to save our souls. As is quite clear, very often to do the work of salvation is to put one's physical well being/comfort in jeopardy. If martyrdom (losing one's life for the Gospel...which certainly is the end of all physical health to be sure) is at one end of the spectrum, then we shouldn't be surprised if lesser martyrdoms are to be found in our life, which while contributing to our spiritual good, may cost us temporally.
