Let me tell you this, OP. Without getting into the complex science of RNA and how your body consumes resources in order to produce over 100 million sperm per ejaculation on average, I will use a generic analogy, likening your balls to grapes.
Let's pretend that you are making wine. In order to make wine, you have to crush a lot of grapes... Not so different from how we expend a lot of sperm and semen in the process of trying to make a woman pregnant. The thing about individual grape fruits, and how they differ from your testicles, is that they are not self-replenishing. Each grape can only be crushed one single time-- you can't crush the same grape multiple times. You can run the skin of a grape through a press to extract the maximum amount of juice, but eventually it will run out and need to be discarded.
The grape vine, however, is different. Heirloom grape vines will each continue to produce new grapes, each containing a seed, throughout the span of its mature life; about thirty years or so. If you look inside of a grape seed, you will find all of the DNA required to produce a new grape vine, which is nearly identical to the plant it came from... Likewise to how we produce children which look like us. In order to produce new grapes, the grape vine draws on nutrients from itself, which it then replenishes by drawing on the soil.
Despite the visual similarity of the testicle to a grape, the male reproductive system is more akin to a vine-- it produces new fluid containing seed, as a grape does, without being destroyed on delivery. In order to make children, we mix our "grape juice" with a woman's "yeast," and allow it to "ferment" in her womb for 9 months. In order to replenish that liquid seed, our testicles feed upon us in various ways.
>TFW you realize that, every time you ejaculate, YOU are the one getting crushed to make "wine," not your "grapes."
>YOU are also the very soil that your "grapes" replenish themselves from.
