Sperm Pain or Painful ejaculation (painful orgasm) is described as a pain or a burning sensation that occurs when a man ejaculates. He may feel pain between the anus and the genitals or in the testicles. Painful ejaculation has psychological effect on the sufferer including damaged relationships, eroded self-esteem, and turning pleasure into immeasurable pain. It can be a frightening experience, but it is nothing to be ashamed of. For most men, it manifests as pain during or immediately after ejaculations. It is highly treatable and can be the first symptom of another problem, such as swelling of the prostate. The causes are numerous including: Prostatitis:Prostatitis is the term for inflammation or infection of the prostate. It is the most common urological problem in men under 50. Surgery:Some types of surgery can cause several side effects, including painful ejaculation. One of these is radical prostatectomy, a procedure to remove all or part of the prostate and some surrounding tissue. Surgery is used to treat prostate cancer. Cysts or stones: just as in the kidney, it is possible to develop cysts or stones in the ejaculatory duct. They can block ejaculation, causing infertility and painful ejaculation. Trichomoniasis: Trichomoniasis is a sexually transmitted infection that can also cause burning or pain during urination. Radiotherapy: Radiation therapy to the pelvis can cause erectile dysfunction, including painful ejaculation. These side effects are usually temporary. Psychological problems: Sometimes the cause cannot be determined. If you don't have pain when you masturbate, it can be emotional. Consider seeing a therapist investigate this further.
