What is the difference between urology and andrology?

Urology and andrology are actually inseparable. Urology is a branch of surgery, and there is another branch of urinary system, urogenital system, which is a disease path corresponding to specific organs or tissues of men. This is also the scope of our andrology diagnosis and treatment. Some common diseases, such as infertility, testicular diseases, such as hydrocele, epididymitis, and of course prostatitis, and some erectile dysfunction, are all ours. Generally speaking, andrology is a branch of our urology, which is a result of the refinement of the subject. They are inseparable, that is, urology includes andrology, and andrology is an important part of urology.
