Food and medications
Your doctor will probably ask you to stop taking aspirin or other blood-thinning medications several days before your surgery. These can include warfarin (Coumadin, Jantoven), heparin and aspirin, and other over-the-counter pain medications such as ibuprofen (Advil, Motrin IB, others).
Clothing and personal items
Bring a pair of tight-fitting underwear or an athletic supporter to wear after the procedure to support the scrotum and minimize swelling.
Shower or bathe on the day of the surgery. Be sure to wash your genital area thoroughly.
Arrange for a ride home after your surgery to avoid movement and pressure on the surgery area caused by driving.
