Sperm Path from Testis to Ejaculation

Sperm move through a series of tubes from the testis to the urethra before ejaculation. Their journey begins in the seminiferous tubules, where Sertoli cells make fluid that helps push non-motile sperm forward. The sperm then pass through the straight tubules and into the rete testis, which serves as the first connected path...

Inside the seminiferous tubule of the testis, fluid from the Sertoli cells pushes the non-motile sperm through a series of straight tubules into the rete testis.

From these interconnected tubules, sperm is transported into the coiled efferent ductules.

Spermatozoa exit the testes through the efferent ductules and enter the ductus e...
