During a vasectomy, the ductus deferens is cut and then either ligated (tied off) or cauterized (burned) at the ends. Determine the effect of a vasectomy on the passage of sperm from the male's body and the impact on testosterone production
What will be an ideal response?
A vasectomy prevents sperm from leaving the man's body with the semen during ejaculation. Sperm are still produced, but they degenerate and are destroyed by phagocytosis. Semen is also still produced because the vas deferens is cut below the area where the accessory structures secrete the other components of semen. Testosterone production is unhampered because the blood vessels are unaffected. Thus, blood testosterone levels remain normal. For these reasons, a vasectomy has no effect on sexual desire or performance.
