What happens during a vasectomy reversal surgery? When you had your vasectomy surgery, your doctor had blocked the tubes called vas deference to prevent the sperm from flowing in your semen. You had successfully avoided the pregnancy you and your partner did not want. But now you have a change a heart and want to go through a vasectomy reversal surgery. Are you concerned about how safe is the vasectomy reversal surgery? What happens during the surgery? If you have these questions running in your mind, we have got you covered. Read along to find out.

How Is Vasectomy Reversed?


There are two procedures for the reversal of vasectomy. The first method is the vasovasostomy. In this method, the surgeon sews the vas deference from testes to the penis. This way, the sperms from vas deference easily reaches the penis and flows out.


The other method is vasoepididymostomy. Here, the doctor attaches the vas deference to the spermatic cord present at the back of the testicles. Vasoepididymostomy is a complex procedure and rarer than the other easier reversal method. Your surgeon will opt for vasoepididymostomy if they feel that vasovasostomy would not be possible or less effective.

Your surgeon will analyze the fluid from vas deference for the presence of sperm. Then they will decide which vasectomy reversal is suitable for you at the time of the surgery. In some cases, there can be a requirement of the combination of both the reversal methods. The surgeon will perform vasovasostomy on one side and vasoepididymostomy on the other side. The longer you have your surgery after the vasectomy, more likely you are to have vasoepididymostomy on either or both sides.

Are There Any Side Effects?

Vasectomy reversal procedures usually do not have side effects other than pain. But some patients may experience other side effects in rare cases. The side effects include bleeding and painful swelling in the scrotum. The infections are possible in some cases.

However, you avoid the chances of getting an infection if you have your vasectomy reversal done by a highly trained and experienced surgeon. If you get an infection after the surgery, your doctor will prescribe you some antibiotics. Severe and persistent pains usually do not happen after vasectomy reversal surgery. However, if you experience severe pain for long, do check with your doctor immediately.

How Would I Know The Reversal Worked?

You must not continue your sexual practice too soon after the vasectomy reversal. Wait for at least two to three weeks until your genitals recover.  You will know if your vasectomy reversal is successful if the sperm began to appear in the semen within a few months.

Your doctor will examine your semen sample for four to six months. If you have Vasoepididymostomy as your reversal method, it will take between six to twelve months before your sperm flow returns. In some case, it may take a year as well.

One thing you must know is that all vasectomy reversal procedures do not guarantee a successful pregnancy rate. Vasectomy is reversible even after passing of several years since the original vasectomy. But the longer the time between vasectomy and its reversal, the lesser the chances are of its success.
