Scrotal Hematoma After Vasectomy

Many men choose a vasectomy for permanent birth control because of the many benefits. It’s cheaper and easier than permanent birth control for women. Plus, the recovery time is much shorter and there is less risk of serious side effects.

However, like any surgical procedure, complications can still occur. While rare, a scrotal hematoma is something that men should be concerned about after a vasectomy. A hematoma refers to a collection of blood outside the blood vessels. Scrotal hematomas occur in roughly 2% of vasectomy cases

There are two main types of vasectomies: conventional and no-scalpel. A conventional vasectomy uses a scalpel to make two small incisions on both sides of the scrotum. A no-scalpel vasectomy, on the other hand, uses a small hole. Scrotal hematomas are more common with the conventional method. 

Scrotal hematomas typically occur when a vein next to the vas deferens is cut during the vasectomy. Because the testicles hang downward, blood from the vein can run downward into the scrotal sac. This can cause it to pool and even fill up in severe cases.

Experience Plays a Role

The surgeon’s experience plays a role in determining post-operative complications. More experience correlates to fewer complications. Studies show that surgeons who performed at least 50 vasectomies per year had a complication rate that was 66% lower than those who performed fewer than 10 vasectomies per year.

Symptoms of Scrotal Hematoma

While uncomfortable, a scrotal hematoma rarely results in long-term damage. Look for these symptoms:

  • Swelling
  • Bruising
  • Pain

At first, the hematoma will feel like a lump and harden over time. Because hematomas can vary greatly in size, the symptoms will vary. A small one may not be painful at all, while a large one may look like a third testicle. 

Treating a Scrotal Hematoma

Men who experience the above symptoms should see their doctor immediately for treatment. While most hematomas resolve on their own without medical treatment, surgery may be required in some cases.  Draining may be required in some cases, but the primary treatment includes anti-inflammatory medication, hot baths, and wearing an athletic supporter. It’s important to be patient, as the  hematoma can take a week or two to dissolve as the mass of blood gets reabsorbed into the body. 


Using a highly experienced no-scalpel vasectomy practitioner can dramatically reduce the chances of scrotal hematomas and other complications. Because there is no scalpel involved, there is a far lower chance that the veins alongside the vas deferens will be accidentally cut.
