No. Testosterone is produced in the testicles but is not affected by tying off the vas deferens.

This is a common question. A vasectomy blocks the drainage of newly produced sperm from the testicles, but should have no effect on the production of testosterone by different cells deep within the testicle--called Leydig cells, which are outside the sperm producing tubes.

Studies have been done looking at any effect of vasectomy on testosterone levels and though some studies have suggested that there can be an increase in testosterone, the general consensus is that vasectomy does NOT change testosterone levels.

The short answer: No. The longer answer: Testosterone is made in a different cell in the testes, it is not affected by the vasectomy procedure.
