Patient's question:

There is a week

Doctor's answer:

There are many factors that can cause testicular swelling and pain, such as orchitis, testicular tumors, testicular cysts, hydrocele, epididymitis, seminal vesiculitis, prostatitis, etc. The testes are important reproductive organs in men, and if there are problems with the testes, it can directly affect future fertility and sexual function. It is recommended that you undergo relevant tests to confirm the diagnosis and receive targeted treatment.
