A vasectomy is a safe and effective urologic procedure that renders a man sterile or unable to father a child. This procedure is typically performed in the urologist’s office, but at times can be done as an outpatient at the hospital.

The vas deferens are the tubes that carry the sperm to the penis from the testes. During this procedure, the vas deferens are cut to keep the sperm from traveling to the penis. The testes continue to produce sperm after this procedure but the sperm have nowhere to go, so they die and are absorbed by your body. The prostate continues to make seminal fluid so you will continue to ejaculate, but there will not be any sperm in it.

Patients do not have any changes in hormone levels or male characteristics after this procedure, and erections are typically not affected.

After this procedure, it is important to know that there will still be some remaining sperm in your semen. It is important to use some other form of birth control until your semen has the absence of sperm.

You will be asked to provide two semen specimens post-vasectomy, typically four to six weeks apart to confirm the absence of sperm. This test is generally done after there have been at least 10 to 20 post-vasectomy ejaculations.


Pre-Procedure Checklist

  • Eat normally the night before surgery. Withhold all food and drink after midnight and on the morning of surgery.
  • Do not take any aspirin, or any medications containing ibuprofen (Advil, Motrin, Aleve) at least 7 days prior to the procedure, as these medications have a side effect that can lower blood clotting ability.
  • Someone will need to drive you home after the procedure, following your recovery from the procedure. Buy some frozen peas or mixed vegetable bags from the grocery to use as a cold packs to the area after the procedure.

Post-Procedure Checklist

Please call our Call Center at 217-545-7500 to schedule a quick post-operative appointment with Dr. Kohler or the nurse practitioner. This appointment should be about 1-2 weeks after your surgery date.



You should rest for the first 24 hours following the procedure to lessen the chance of swelling. Avoid strenuous exercise (including sex) or heavy lifting for 1-2 weeks. After that, you can do all of your normal activities, but at the start, let discomfort be your guide: if it feels uncomfortable, slow down

Wear supportive underwear (jock-strap or brief-style underwear) for one week following surgery to reduce pain and prevent swelling.

Apply ice packs (frozen peas or mixed vegetables work well) to the groin area several times daily for the first 24 hours to help with swelling. You can apply ice as often as desired.



Take your prescribed pain medicine, usually Norco, for moderate discomfort. Always take the Norco with food in your stomach, so that you do not get nauseated. You can take Ibuprofen 600mg every 6 hours as needed for mild pain.



Do not shower for 24 hours after your surgery. After 24 hours, you may shower, but do not sit in water for at least 7 days.

Problems to Report

Problems you should report to Dr. Köhler (217-545-7500) if they occur:
1. Fever > 101° F, shaking and chills.
2. Expect a small amount of bloody discharge from the incisions. However, call if it continues and the incision site becomes red, painful or separates.
3. Scrotal hematoma: Extreme discoloration (black and blue) of the scrotum and continuing scrotal enlargement/swelling with associated throbbing pain. Swelling the size of a grapefruit is too large- call to report.
