Testicle size is a matter we live with.....live with what we were given!
(There's no way to PERMANENTLY enhance testicle size.)
Pumping (and other manipulation) doesn't affect the actual testicles themselves...only surrounds them with accumulated fluids which get re-absorbed ultimately and everything returns to normal. The "bigger look" is temporary at best. There are some variations in vacuum pumping devices whereby part of the pumping procedure "pumps" both the penis and the testicles together in a larger than typical vacuum tube. This method will improve the elasticity of the scrotum skin (ballsac) to some degree over a very longer period of time but, again-the individual testicle size always remains the same. Some men swear their testicles "feel bigger" from this pumping procedure and indeed they may respond to all the attention and increased blood flow to them!....but don't expect any gains to be long-lasting. That's just the way it is, sorry.
Increasing ejaculate amount is debateable. Some will say certain nutritional supplements could bring larger, (thicker) volumes of semen. I've been using "male-health related supps" for over three years and I can't say there's been all that much difference in overall semen quality or quantity. Libido and energy levels though--are much improved (as is erection frequency and improved "hardness".)
Actually, the amount of a man's ejaculate could very well depend largely upon the degree of the sexual stimulation itself. Being extra "turned-on" is likely to yield a much more major shooting for many of us. For the few of us who can, two ejaculations back to back over a few minutes can produce surprising amounts the second time. Age of the man factors in a lot of this, too. Then there's deliberately holding back an ejaculation when you're close and then "restarting" the arousal process (over several times) which can lead to more powerful ejaculation, too. (This is known as "edging" and it requires some practice to "perfect" this technique!
But, it's the tried-and-true premise of not ejaculating for a few days (to allow the male system to build back up) and drinking lots of fluids which are probably among the better routes to producing more semen upon demand. These "remedies" DO seem to work for most of us. I admit, NOT ejaculating for several days is tough going for some men. (After all, we have our reasons!
