I am going to get open mesh ingunial hernia repair surgery this week. Will I be able to have sex after the surgery?

Yes. For open and laparoscopic inguinal hernia operations, i tell my patients to return to call mental activity as tolerated by pain. This is a variable amount of time, but usually most people after open inguinal hernia operations are back to normal activity at 2 to 3 weeks. If any complications arise, obviously this may not hold. There are also exceptions to this rule. Good luck!
