What is the advantage of producing sperm in a system of tubes rather than in a solid tissue?

The sperms are the male gametes these develop in the testicles which are the male reproductive organs. Each testes consists of system of tubes called as seminiferous tubules. In seminiferous tubules the spermatogenesis takes place in which the development sperm cells receives nourishment for maturation.

The sperms moves from the seminiferous tubules to the duct like vas deferens from where the sperm moves to be ejected out of the body. If the sperms were produced by the solid tissue except the seminiferous tubules the movement of sperms will be restricted the ejection process may get slow down.
