Male Sexual Response: Erection & Ejaculation

Sexual stimulation can take various forms, such as physical touch and visual or auditory cues. When this happens, the parasympathetic reflex in the sacral portion of the spinal cord is activated. This reflex stimulates the release of nitric oxide (NO), which then dilates the arterioles in the penis, increasing blood flow to the erectile tissues - the corpora cavernosa and corpus spongiosum.
The blood filling the erectile tissues compresses the veins, which helps to prevent blood from leaving...

Most men retain ejaculatory function after prostate brachytherapy, but many experience reduced ejaculate volume and orgasm quality. This study analyzed ejaculatory function changes post-treatment for localized prostate cancer.

Area of Science:

  • Oncology
  • Urology
  • Men's Health

Background:

  • Ejaculatory function is a critical aspect of male sexual health.
  • Prostate cancer treatments, including brachytherapy, can impact sexual function.
  • Limited data exists on ejaculatory function post-prostate brachytherapy.

Purpose of the Study:

  • To conduct the first detailed analysis of ejaculatory function in men treated with permanent Iodine-125 (125I) prostate brachytherapy.
  • To assess changes in ejaculatory frequency, volume, pain, pleasure, and orgasm quality.

Main Methods:

  • A mailed questionnaire based on the Male Sexual Health Questionnaire was used.
  • 241 sexually active men treated with (125)I prostate brachytherapy for localized prostate cancer were analyzed.
  • Five aspects of ejaculatory function were evaluated: frequency, volume, dry ejaculation, pleasure, and pain.

Main Results:

  • 81.3% of men maintained ejaculatory function, but rare/absent ejaculation doubled.
  • 84.9% reported reduced ejaculate volume, and 18.7% experienced dry ejaculation.
  • Painful ejaculation increased from 12.9% to 30.3%; orgasm quality also declined.

Conclusions:

  • The majority of men retain ejaculatory function after prostate brachytherapy.
  • Significant reductions in ejaculate volume and orgasm quality are common post-treatment.
  • Age and pre-implant erectile function influence ejaculatory function outcomes.
