Testicle
Make it clearer
The testicle is a crucial part of the male reproductive system, and it does two jobs at once: it makes sperm and it makes androgens, the male hormones that keep that system running.
Inside, it is divided into compartments called lobules, and within them are very fine tubes called seminiferous tubules, and that is where sperm develop. Those tubes are tightly coiled on themselves, like a long hose wound onto a reel, and that is why they make up the bulk of the organ. There is one detail that matters: this sperm production happens inside the testicle and proceeds best when the testicle stays below the body's core temperature.
In brief
The testicles are a crucial part of the male reproductive system: they produce sperm and androgens, the hormones that support male reproductive physiology.
Within the lobules, sperm develop in the seminiferous tubules, which are tightly coiled and make up the bulk of each testicle.
The seminiferous tubules are coiled like a hose stored on its reel, which is how so much tubing fits in so little space.
This production takes place inside the testicle and proceeds best when the testicle stays below the body's core temperature.
