What are the Causes of vasectomy failure?

Vasectomy has approximately the same level of effectiveness as the pill; indeed, it is usually only about 1 in 100 chance of failing. The most common schedule for vasectomy failure is directly once the process is complete. That is why doctors advise their patients to use another form of contraception until a follow-up exam-including a semen sample, determines that the vasectomy been successful.

Time

After the completion of a procedure vasectomy, sperm can remain active in the male reproductive system for several weeks. Therefore, during unprotected sex this period can result in pregnancy. Doctors usually take a semen sample 6 to 8 weeks after vasectomy to verify the sperm count and the success of the procedure.

Misconceptions

Many people believe that vasectomy prevents a man to ejaculate in total; This is false. A vasectomy prevents the release of sperm when a man ejaculates, but not prevent or stop ejaculation altogether.

Considerations

Very rarely, vasectomy is unsuccessful. This is sometimes due to a technical error on the part of the surgeon; However, most often it is caused by the spontaneous reconnection cut ends of the vas deferens, which are cut to prevent sperm released during ejaculation. This connection is known as spontaneous recanalization.

Prevention / Solution

To reduce the risk of reversal, some doctors prefer to leave a space between the two cut ends of the vas deferens. Although this is not a common procedure, it is done by some doctors who believe that it can reduce the chances of vasectomy failure.

Statistics

About 0.5 to 1 percent of all vasectomies fail. This variation is mainly due to how the procedure is performed and whether or not the patient returns to the semen test monitoring.
