Even so, such injections could still cause you to become sexually sterile, adversely affect testosterone production or contribute to an infection and complications.
I'd stay away even from sterile distilled water. There is a reason for saline, it contains approximately the same amount of salts as the body tissues.
So it works this way: water moves to the place with higher concentration of salts, as to equalize salinity. This is called osmosis (http://en.wikipedia.org/wiki/Osmosis).
Now take your testicle cells and distilled water. After injection, salinity of injected water is zero. Salinity in surrounding cells is higher, so the water starts moving through the cell walls inside the cells.
The outcome depends on the amount of water. Too much pressure, and cells do burst. End result could be close to the one with alcohol injection, just much, much slower.
