Patients with chronic prostatitis experiencing painful ejaculation mainly results from the presence of the ejaculatory ducts within the prostate. When the prostate is inflamed, it leads to congestion and swelling, which compresses the ejaculatory ducts causing them to narrow. During ejaculation, due to the high pressure of ejaculation, semen passes through these narrowed ducts producing a significant pain sensation. For this condition, active treatment targeting the type of chronic prostatitis is necessary. If it is caused by bacterial infection, prompt antibiotic treatment should be administered regularly. After controlling the inflammation, the congestion and swelling of the prostate will gradually subside, and the symptoms of painful ejaculation will also alleviate. Patients with chronic prostatitis should pay attention to strengthening physical exercise, maintaining a light diet, and controlling the frequency of sexual activity to reduce prostate congestion and swelling.
