A prostate massager is an instrument used to massage the prostate gland. Due to the special location of the prostate gland, patients are unable to massage the prostate gland by themselves, and the prostate massager is to help patients to massage the prostate gland. The prostate massager belongs to a kind of physical therapy, the specific method of use is to put a condom on the probe, the patient lying on the side of the examination bed, apply lubricating oil, inserted through the anus, and then find the position of the prostate gland in contact with the anterior wall of the rectum. After the fixation is done, the instrument can be activated for massage physiotherapy. However, because it often works inside the rectum, it is particularly susceptible to bacterial growth, and if the massager is not kept hygienically clean, there may be a risk of infection.
