Explanation:

Mature spermatozoa leave the testes through the ductus deferens. A vasectomy involves cutting and sealing this structure to prevent sperm from entering the ejaculatory fluid. The urethra is the final passage for semen during ejaculation but not the initial exit - point from the testes. Seminiferous tubules are where sperm are produced. Prostatic ducts are related to the prostate gland's contribution to semen, not the exit of sperm from the testes.
