Reproductive system diseases refer to a group of diseases that affect the structure, function, and reproductive ability of human reproductive organs. They can be divided into two main types: male reproductive system diseases and female reproductive system diseases, covering congenital developmental abnormalities, organic injuries, infectious diseases, and sexually transmitted diseases. Male conditions mainly manifest as abnormal urination, urethral discharge, and sexual dysfunction, while female conditions are characterized by reproductive tract infections such as vaginitis and cervicitis.
