Yes it does make you sterile and your semen has no sperm. So you cannot be a sperm donor. They may however aspirate your testicles to harvest sperm for in vitro.

Once a patient has had a vasectomy, he is no longer ejaculating sperm. Thus, at this point, he would not be able to be an anonymous donor. However, he does continue to make sperm; they just do not leave the scrotum. If he should choose to be an anonymous donor in the future, he would need to undergo a vasectomy reversal. Should he wish to be a designated donor--in other words, have his sperm used for someone that he knows--sperm could be retrieved from the scrotum. However, these sperm could only achieve a pregnancy when combined with an in vitro fertilization cycle.

After a successful vasectomy, sperm can only be obtained by a procedure, either an aspiration of the epididymis or by reversal. Even then, the quality would be poor and likely exclude you as a donor. Sperm banking may be done prior to a vasectomy but, as mentioned above, would not be easily obtained after.

Once the vas deferens is closed with a vasectomy, you cannot collect any more sperm, unless you have a reversal.
