Hematoma After Vasectomy

July 8, 2025

Hey fellas, Alex Hughes here—lead APP at Austin Urology Institute. Let’s have a quick, real-talk moment about something that might show up after your vasectomy: the hematoma. It’s not common, but when it happens, you’ll know.

A hematoma is basically a big ol’ bruise caused by bleeding under the skin. During a vasectomy, we carefully cut and seal the vas deferens. Sometimes, a small blood vessel doesn’t get the memo and leaks, forming a firm, painful mass. It can look scary, feel worse, and give you some serious “what did I sign up for?” energy.

Vasectomy Bruising: Signs it Could Be a Hematoma

  • One testicle feels significantly larger or tighter than the other
  • Deep purple or black bruising that spreads into the groin or thigh
  • Pain that feels more intense than expected
  • You’re waddling, icing, and saying words your kids shouldn’t repeat

Hematoma After Vasectomy: What You Should Do 

Ice packs are your best friend. 20 minutes on, 20 minutes off—repeat like it’s your job.

  • Supportive (and yes, tight) underwear keeps swelling down.
  • Rest. Elevate. Netflix and literally chill.
