Question: if a man has a vasectomy what comes out?
Answer: Sperm leaves the epididymis by way of the vas deferens (this is the tube that is divided during a vasectomy) which travels to join the seminal vesicles and prostate. Sperm mixes with fluid from the seminal vesicles and prostate to produce semen, the fluid that comes out from the penis at the time of ejaculation.
