Interesting question. If there's no surgery that will do the trick, maybe they have meds. Since the prostate produces most of the semen and they have meds to shrink the prostate (finesteride), why not something that enlarges it? If not for that purpose than as a side effect. I took flowmax once following a medical procedure to remove kidney stones and jacked off later that day and shot absolutely nothing. Not a drop. I freaked. I felt like the main character in "Something About Mary" who jacked off and couldn't find where his shot landed. I learned later that it's a side effect experienced by some. If Flomax can cause you to "dry up", there's gotta be something out there that does just the opposite.
