The investigators would like to conduct a multicentre randomised controlled clinical trial to compare the difference in early postoperative pain after unilateral primary inguinal hernia repair in males. The procedures will be performed in day surgery. Early postoperative pain is defined as the pain during the first month, with a special interest in the first two weeks. In addition, the investigators want to measure the possible benefit in terms of time to return to work, daily activities, quality of life, operation length, complications and long term postoperative pain.
