I can see the study being published:
"Dr. Jack MeHoff, P.h.d., had 6 test subjects: 3 would be subjected to having sex (one with another male since he was gay), and the other 3 would masterbate. The study was conducted over a 6 month period. All would have 3 oragsms per day.
At the end of the 6 month period, the 3 males who were subjected to having sex 3 times a day (including the homosexual) showed no signs of gyno.
The 3 who masterbated 3 times per day, however, showed swelling of the nipples. It must also be noted that at 3 times per day, they started to have itchy nips after about 3 months, but continued to whack it anyway, because they said they were "horny."
Dr. MeHoff concluded that having sex did not have any significant influence on the release of prolactin. On the other hand, the ones masterbating had high levels of it, probably due to the exertion of the right hand, somehow exacerbating the problem of the release of prolactin while cumming."
