A saline injection is when a sterile saltwater solution (saline) is injected into the body. It’s typically used for medical purposes, like rehydration or wound care.
When someone gets a saline injection in the testicles, it’s not a medical procedure but more of an unusual practice some people do. The saline temporarily inflates the scrotum, making it look larger, and the body absorbs the fluid over time. It’s often done as a body modification or for aesthetic purposes, but it comes with risks like infection or tissue damage if not done safely.
