How can a man cum after he has done vasectomy? how does the sperm go up to the penis ?
Hi Levy,
A vasectomy cuts or blocks the vas deferens, the tube that carries sperm from the testicles. Sperm makes up only a very small portion of your ejaculate. The rest of your semen comes from the prostate.
You won't notice a change in volume of your ejaculate. It's too little with sperm being less than 5% of the volume.
