1. Inguinal hernias have been repaired with artificial material mesh (polypropylene, 1958) for more than 50 years, and currently, more than 10 million pieces are used clinically worldwide each year (and more than a million in China), with substantial clinical evidence that the overall efficacy of repair with the patch is significantly better than repair with sutures alone. There is no evidence yet that the material is associated with male infertility in humans. 2. The possibility that patch repair may affect postoperative infertility is still only a hypothesis. 3. One of the factors that really affects inguinal hernia surgery the most on the reproductive function is still the operator’s operation (whether it is standardized, whether it is standardized, whether it is detail-oriented. At present, there are two types of people who say “something” about the patch: one is individual operators of hernia surgery, who appoint themselves as “chief experts in hernia surgery” and say NO to patches; the other is those who sell biological patches, both because of interest. In fact, both of them are “fooling”.
