What is vasectomy recanalization?

The vasectomy is typically an outpatient procedure where the doctor cuts the tubes known as the vas deferens that carry sperm to the penis 3. In rare instances the vas deferens can heal itself in a way in which the tubes reconnect and allow sperm to be released during ejaculation. This complication is known as recanalization.

Does recanalization of the vas deferens affect pregnancy?

Since semen is still present during ejaculation, it may be difficult to know for sure if the vas deferens has reconnected. If sex occurs without an additional form of contraception, recanalization is likely to lead to pregnancy in the same way it would if there had never been a vasectomy.

What are the conditions that affect the vas deferens?

The vas deferens is affected by various conditions, as well as being the target of vasectomy surgery.

How can we prevent recanalization?

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.

How often do vas deferens grow back?

However, in some cases, the vas deferens grow back several years after the procedure. The growth may continue until a connection is recreated, allowing the free flow of sperm to the urethra.

Associated Conditions. Tests. The vas deferens are an important part of male reproductive anatomy. These paired muscular tubes are also called the ductus deferens. They function to carry sperm from the epididymis to the urethra where it leaves the body during ejaculation.

How does the vas deferens propel sperm forward?

The vas deferens propels the sperm forward by way of muscular contractions. When sperm reaches the ampullae it is joined by secretions from the seminal vesicle. From the ampullae, the seminal fluid is propelled through the ejaculatory ducts, past the prostate gland where a milky fluid is added to the mixture, and finally through the urethra where it exits the body.

What is the outermost layer of the vas deferens?

The actual structure of the vas deferens has three layers. The outermost layer is made of connective tissue and called the adventitia.
