How Common Is Infection After Vasectomy?
How often do infections occur after a vasectomy? Fortunately, the risk is very small when the procedure is performed using modern minimally invasive techniques.
The safest approach is a minimally invasive, no-scalpel vasectomy that requires only a single small opening in the skin. This type of technique is associated with the lowest likelihood of infection.
When this minimally invasive method is performed by an experienced provider, infections involving the scrotum are uncommon.
Because the infection rate is already so low with this technique, routine antibiotic use is generally unnecessary.
Any surgical procedure carries some infection risk because the skin must be opened to reach the tissue beneath it. The skin normally serves as a protective barrier against bacteria. In general, larger incisions increase the possibility of infection, while smaller openings reduce that risk.
A minimally invasive vasectomy typically requires just one, and occasionally two, very small openings in the scrotal skin.
For this reason, patients who choose a minimally invasive technique such as the His Choice No-Scalpel Vasectomy can feel confident that the likelihood of developing an infection after the procedure is very low.
Traditional vasectomy methods typically involve using a scalpel to create two separate incisions—one on each side of the scrotum. These cuts are generally larger than the small openings used in modern no-scalpel techniques and involve full-thickness skin incisions.
Because of this approach, the two cuts made during a conventional vasectomy are usually larger than the single spread opening created during a His Choice vasectomy.
Some clinical studies have shown that infection rates with traditional scalpel techniques can be several times higher than those seen with no-scalpel procedures.
Minimally invasive techniques, such as the His Choice No-Scalpel Vasectomy, require only one small opening located near the center of the scrotum. In addition to the smaller skin opening, the amount of surgical instrumentation used inside the scrotum is kept to a minimum.
Using a tiny opening and limiting internal manipulation helps reduce the chance that bacteria will enter the scrotum. When this approach is used, the risk of infection is typically very low—generally less than 1 percent.
What are symptoms of vasectomy infection?
Most infections after vasectomy first appear as redness in the skin of the scrotum. This redness occurs because the body’s immune system increases blood flow to the area while trying to fight bacteria. If the infection continues to progress, the redness can spread outward through the surrounding skin. As this happens, the tissue may become thicker, more swollen, and increasingly tender due to the inflammatory response. In more advanced cases, symptoms such as fever, generalized body aches, or drainage from the skin opening may occur.
It is normal to notice a small amount of redness or mild swelling around the skin opening where the procedure was performed. This mild irritation usually improves during the first week as healing occurs. With an infection, however, the redness and swelling gradually worsen rather than improve.
Many people expect infections to appear immediately after surgery, but that is usually not the case. Bacterial infections typically require several days to develop. In most situations, signs of infection become noticeable about five to seven days after the procedure.
Surgical infections can develop at any point during the first 30 days after an operation. However, it is very unusual for a new infection to appear more than a month after a procedure has been performed.
Fortunately, infections following vasectomy are uncommon. When they do occur, they are most often recognized about one to two weeks after the procedure.
In most cases, treatment simply involves a course of oral antibiotics. Only in very rare situations would stronger treatment—such as intravenous antibiotics or hospital care—be necessary.
Where are vasectomy infections located?
Infections after minimally invasive vasectomy are rare but can occur in the scrotal skin, superficially underneath the skin, deep inside the scrotum, in the epididymis, or higher up the genital tract in the prostate. Most infections after vasectomy are in the scrotal skin and around the skin opening(s).
Scrotal skin. Scrotal skin infections are either from the patient’s normal skin bacteria, from bacteria introduced during the vasectomy procedure, or bacteria from the patient’s environment (ie showers, bath tubs, etc). These infections are easily diagnosed after observing expanding skin redness, fluid drainage from the opening, and/or fevers and chills.
Superficial scrotal abscess (underneath the skin). These are infections caused by bacteria that gain access to the scrotum during or after the vasectomy procedure. This bacteria may collect underneath the skin and form an abscess. An abscess is a collection of infection. An abscess may feel like a large tender mass the size of a grape or larger. Usually these will continue to grow until they spontaneously drain or they are drained by a medical professional.
The symptoms from a vasectomy abscess do not usually begin until about 7 days after a vasectomy procedure. Once they are detected, they gradually increase in size. As the size increases, the symptoms increase. Once they are drained rapid improvement is experienced. Drainage and antibiotics are usually required for treatment of an abscess.
Deep scrotal abscess (deep inside the scrotal space). These are collections of infections that are deeper in the scrotum. They are not just underneath the skin but deep inside the scrotum in the same area where the vas deferens and testicles reside. These infections may feel about the size of a third testicle or larger. They are usually very symptomatic causing severe scrotal pain, fevers, and chills.
A scrotal abscess can cause severe pain, fevers, chills, and body aches. A testicular abscess usually is a deep scrotal infection that also involves the testicle.
Deep scrotal abscess are serious and often require hospitalization, surgical drainage, and intravenous antibiotics.
Bacterial epididymitis. Bacterial epididymitis is inflammation in the epididymis caused by bacterial infection.
The epididymis is a structure that is below the vasectomy site and low in the scrotum. The epididymis is a soft “C” shaped structure that lies on the back of each testicle. If bacteria are able to gain access to the epididymis then you can get bacterial epididymitis.
- Bacterial epididymitis after vasectomy is extremely rare.
- Inflammatory epididymitis after vasectomy is extremely common.
Most cases of epididymitis after vasectomy are misdiagnosed as bacterial epididymitis. The term epididymitis simply means ‘inflammation of the epididymis’.
Most cases of epididymal irritation that occur after vasectomy are not due to bacteria. Instead, the symptoms usually result from sperm accumulating behind the vasectomy site. This buildup can create pressure, stretching, and inflammation within the epididymis. This process is known as inflammatory epididymitis and is relatively common during the recovery period after vasectomy.
If a patient visits an urgent care clinic with scrotal discomfort after a vasectomy, they are often given the general diagnosis of “epididymitis,” prescribed antibiotics, and advised to follow up with the physician who performed the procedure.
In many situations, those antibiotics are not actually necessary because the problem is not caused by a bacterial infection. The discomfort is typically related to sperm congestion and the resulting inflammatory response.
Inflammatory epididymitis most often develops sometime between one week and three months after the procedure. Treatment usually focuses on reducing inflammation with non-steroidal anti-inflammatory medications such as ibuprofen or naproxen. These medications often provide quick symptom relief. As healing progresses, the body gradually adapts and the symptoms usually improve over time.
A different and much less common issue is bacterial prostatitis. This can occur if bacteria travel upward through the reproductive tract and infect the prostate gland. When this happens, symptoms generally appear later than most other post-vasectomy problems, typically between about 10 and 28 days after the procedure.
Patients who develop this condition commonly report urinary difficulties, discomfort in the lower pelvic region where the penis meets the abdomen, and symptoms similar to the flu. Some individuals may also develop a fever. When bacterial prostatitis occurs, it is typically treated with a longer course of oral antibiotics, usually lasting about three weeks.
Some vasectomy providers believe that prostate infection is not a complication related to vasectomy. However, based on our experience, we have occasionally observed this problem, occurring in roughly 1 out of every 1,200 patients who undergo the procedure in our practice.
What are the chances of infection after vasectomy?
Many people find it difficult to interpret medical risk statistics in a way that feels meaningful for their own situation. Numbers and percentages can be hard to translate into a personal understanding of risk, and individuals may perceive the same statistic as either very small or very significant depending on their perspective.
For example, when a doctor describes a complication as having a “low” risk, what does that actually mean? Terms such as low, high, rare, or uncommon are somewhat vague and can be interpreted differently by different people.
Consider this example: we might say the chance of developing a rash after a procedure is low at 2%. At the same time, we could say the risk of dying from a procedure is also 2%. Even though the percentage is the same, the way people react to those risks is very different.
Most people would consider a 2% chance of a rash to be minor and acceptable, while a 2% chance of death would seem extremely high and unacceptable.
Because of this, percentages alone can sometimes be confusing when discussing medical risks. For instance, a doctor might say that the chance of infection after a procedure is 10%, but that number can be difficult for many people to fully interpret without additional context.
Some people view a 10% risk as relatively small, while others consider it quite high. Interestingly, many individuals react differently when the same statistic is expressed in another way. Saying something has a 10% chance of happening may seem acceptable to some, but when it is explained as a 1 in 10 chance, it may suddenly feel like a much greater risk. Mathematically these numbers are identical, but people often interpret them differently.
How a person perceives risk depends on several factors, including their outlook, their familiarity with statistics, and how serious the potential outcome might be.
So what is the actual infection risk after a His Choice Vasectomy?
We find it helpful to explain this risk using real-world experience rather than abstract percentages. Looking at the outcomes of our own patients helps illustrate how uncommon infection truly is after this procedure.
During the first ten years of performing the His Choice vasectomy technique, we treated more than 10,000 patients.
Among those patients:
Fewer than five developed minor skin infections
About seven experienced prostate infections
One patient developed a superficial scrotal abscess
In one group of approximately 8,000 patients, around 13 developed some form of infection following vasectomy, which represents about 0.2%. In other words, 7,987 of those patients did not develop an infection.
Minor skin infections are the most typical type when they do occur. These usually appear about five to seven days after the procedure. The skin around the small scrotal opening may become red and irritated, and there may be a small amount of drainage. In most cases, a brief course of oral antibiotics resolves the issue. In some situations, what appears to be infection may actually be irritation or delayed healing caused by excessive cleaning of the skin opening.
It is also normal to notice mild redness or slight swelling around the opening in the scrotal skin during the first few days after surgery. This reaction reflects the body’s normal immune response as healing begins. Typical healing-related redness improves during the first week. In contrast, a true infection usually causes the redness to spread outward from the opening and worsen during that same time period.
Prostate infections after vasectomy are uncommon. In fact, many clinicians do not consider prostatitis to be a complication related to vasectomy. Based on our experience, however, we have occasionally seen this occur. In our practice, it appears to develop in roughly 1 out of every 1,200 patients.
Typical symptoms include pelvic discomfort, often felt in the area where the penis meets the lower abdomen. Patients may also experience fever, difficulty with urination, and a general sensation of pressure or heaviness in the pelvic region. Body aches and a feeling similar to having the flu are also common. These symptoms usually appear later than most other post-vasectomy issues, typically between 10 and 30 days after the procedure. In every case we have encountered, treatment with a three-week course of oral antibiotics resulted in complete resolution of symptoms.
Another rare complication is a superficial abscess beneath the scrotal skin. This is a localized pocket of infection that can grow to the size of a golf ball or sometimes larger. It often causes pain and may be associated with fever. These collections of infection can gradually enlarge until they begin to drain. In the single patient we observed with this problem, the abscess drained on its own and oral antibiotics helped the infection resolve more quickly. The patient recovered without any lasting issues.
No medical procedure is completely free of risk. However, the likelihood of developing an infection after a His Choice Vasectomy is extremely small.
Although infection is always a possibility after any surgical procedure, the chance of a scrotal infection following this type of vasectomy is very low.
His Choice Vasectomy experience: Infection after vasectomy is rare
You can feel confident that infection is an uncommon complication when a modern, minimally invasive vasectomy technique is used.
With the His Choice vasectomy method, the likelihood of infection is well under 1 percent. Because the infection risk is already extremely low, routine antibiotic treatment is generally unnecessary for patients undergoing the procedure at our office. In fact, the chance of developing an infection after this technique is much closer to zero than to one percent.
If you are interested in a minimally invasive approach, you may want to consider the His Choice No-Needle, No-Scalpel vasectomy technique.
To locate a provider in your area, you can search for His Choice Vasectomy locations.
Another benefit of this approach is that many of the traditional aftercare steps associated with older vasectomy methods are often unnecessary. Patients typically do not need ice packs or frozen peas—and routine antibiotics are also not required when the procedure is performed using this technique.
