Abstract: Young patients have unique characteristics in terms of body structure and fertility needs. There is currently no consensus on the definition and treatment of inguinal hernia in adolescents and young adults. Biodegradable meshes are materials derived from homologous or heterologous tissues, which retain the three‑dimensional fiber structure containing collagen after special processing. They can meet the requirements of high comfort and low impact on fertility while ensuring repair strength. The authors define inguinal hernia in young adults based on recent research results and summarize the application effect of biological meshes.
