Purnudism is a type of hernia that specifically affects the genital area. It occurs when there is a weakness or tear in the abdominal wall or inguinal canal, allowing the scrotum and sometimes the testes to herniate or protrude through the opening. The condition is relatively rare, and there is limited data on its prevalence. However, it is estimated to occur in approximately 1-3% of males, often presenting in infancy or early childhood.
