Great article, well written and god conclusions of collected data.
How ever I am still curious if creating a “shortage” of sperm and decrease of testosterone by cycles of repeated ejaculations during a short period of time, maybe during the course of hours followed by “rest-days” if that over time would provoke the body to produce more Testosterone and sperm in a response to “progressive overload”.
Since this is the way the body handles a lot other things that challenges it´s system with everything from resistance-training, “repeated skin-abrasion”, bacteria and even some toxins.

NOTE: Some have argued that fish oils are oxidative upon digestion and that fish oil thus probably does significant aging and cellular damage internally that we may not yet understand. However, several studies suggest this to be a relative non-issue.  In addition, one study also found that additional Vitamin E can protective help overcome most of the small amount of oxidative damage that is done anyway. The study authors found that oxidative products in the urine "more than doubled when the fish oil capsules were introduced but then dropped by a factor of four when vitamin E was added. The vitamin E concentration in the red blood cells dropped very significantly when fish oil was ingested but more than recovered with the vitamin E supplement".
