If I poke a syringe into my testicle and pull, will it remove the semen?

When I started doing that I dicovered I liked the sensation.  

No, you'd have to insert the needle into the epididymis to get some considerable amount of sperm. To get semen, you'd have to reach your prostate or seminal vesicle. 

No, but it will remove permanently remove your ability to get a girl pregnant

idk maybe give it a shot see how it goes

LMAO you have a lot to learn. Testicles don't produce semen smart one. Testicles produce the hormone testosterone and sperm. Semen is produced in the prostate gland.

I don't know, but why the hell would you want to? It would hurt like a b**ch!

try it , see if it works and dosent hurt !!!

This is done to remove sperm from some men who are infertile. You may get some viable sperm doing what you suggest but the fluid you remove will be intracellular testicular fluid containing sperm and not semen. It will be quite painful but if you use a clean needle and clean the area then the danger of you getting an infection and consequential gas gangrene and losing your genitals may be quite small.

If you poke a syringe into your testicle and pull... you WILL know pain and wont care about your "school project" any more.

I would ask the health teacher if he can let you demonstrate on him before you try your theory. Otherwise, great question!
