First Week After Surgery

• Pain is the most common side effect soon after a vasectomy. However, redness and swelling are also common.
  
  

Month Following Procedure

• A month after a vasectomy, the pain and swelling should be completely resolved. However, painful intercourse is still common in men post-vasectomy.
  
  

Rare Complications

• In a few cases, a lump may form in the surgical area. If the lump becomes painful or is accompanied by a fever, further medical attention may be needed. Erectile dysfunction may also result out of fear that sex may be painful.
  
  

Serious Side Effects

• Although rare, abscesses and epididymitis may affect a vasectomy patient. An abscess will occur at the incision site and is a result of an infection. Epididymitis can cause additional pain to a patient because the epididymis tube becomes inflamed as a result of the vasectomy.
  
  

Warning

• Men get vasectomies to prevent further pregnancy. However, additional birth control options should be used at least 3 months post-op, or until testing shows that there are no sperm present.
