vasectomy question

my husband has a vasectomy and after 3-5 ejaculations and 6 weeks he had 2 sperm counts of 0 - he had a blood clot though could that have made it impossible for sperm to get through or should we be safe??

Thanks!!

Hello - thanks for asking your question.

For most men, it takes 10 to 14 ejaculations and 1 to 2 weeks before the ducts are free of sperm. Usually, at least two semen samples are produced and collected for analysis 1 week to 1 month after surgery. When sperm count is zero, the man is sterile.

By blood clot, I am assume that there was a hematoma near the surgical site (which represents 2% of complications).  If the sperm count is zero, then sterility is assumed.  

However, to be absolutely sure, you may want to discuss this issue with your urologist.  

Followup with your personal physician is essential.
