In teleosts, testicular fluid transport presumably is also essential during spermatogenesis, and during hormone-induced hydration of the seminal fluid at spermiation, which may increase the interlobular pressure in the testis, thereby aiding in transport of the sperm through the seminiferous tubules while maintaining the correct osmolality of the seminal plasma (Coward et al.
