Post-Vasectomy Pain Study

This is a prospective four-armed unblinded randomized controlled trial to assess four different potential post-operative treatment options for men who undergo a vasectomy. The aims of this study are: * To determine whether the addition of nonsteroidal anti-inflammatory drugs (NSAIDs) to acetaminophen results in improved pain after vasectomy; * To determine whether the addition of opioid pain medication to acetaminophen and/or NSAIDs results in improved pain after vasectomy; * To determine whether the use of NSAIDs for post-operative pain management increases risk of hematoma after vasectomy.
