Fascial interposition vasectomy involves placing a tissue barrier between the two cut ends of the vas deferens to prevent recanalization thereby increasing the overall success rate of the vasectomy.


What causes recanalization?

Recanalization results from the proliferation of epithelial microtubules through granulomatous tissue between the severed ends of the vas, producing a fistula that allows the passage of sperm.

How common is it for a vasectomy to reverse itself naturally?

Can vasectomies be reversed naturally? A vasectomy is one of the most effective forms of birth control, with a 99.85% effective rate. Once you have been cleared, it's extremely rare for the procedure to fail or reverse naturally. In fact, the risk of failure is less than 1 in 2,000 (less than .

Sperm then travels through the deferent duct through up the spermatic cord into the pelvic cavity, over the ureter to the prostate behind the bladder. Here, the vas deferens joins with the seminal vesicle to form the ejaculatory duct, which passes through the prostate and empties into the urethra.
