I just had my second vasectomy due to canalization. How often does this occur? What are the statistics surrounding this?

The rate of canalization is 1 in 2,000. The overwhelming likelihood is that this time is the "charm!"

1 out of 40,000 is what I quote.

One in two thousand. You should be good to go with another vasectomy but the risk is still one in two thousand for you even after the second one.

Spontaneous recanalization following a vasectomy is incredibly rare, only occurring in 1 out of 2500 vasectomies, according to the AUA - American Urologic Association. Although rare, vasectomies can fail, which is why it is essential to follow up with a post-vasectomy semen analysis.

One in a thousand roughly, though some interesting studies in Europe showed a much higher sperm detection rate. It is thought that the slight count made them essentially infertile. I suspect recanalization on some level occurs more often than we previously thought.
