Summary
Prostate brachytherapy (PB) can lead to erectile dysfunction (ED) in most men, often developing progressively after a symptom-free period. Age, pre-treatment function, and prostate size are key risk factors for ED post-treatment.
Area of Science:
- Oncology
- Urology
- Men's Health
Background:
- Prostate brachytherapy (PB) is a treatment for localized prostate cancer.
- Erectile function is a crucial aspect of quality of life for men undergoing cancer treatment.
Purpose of the Study:
- To analyze the impact of prostate brachytherapy (PB) on erectile function in men with localized prostate cancer.
- To identify risk factors associated with the development of erectile dysfunction (ED) after PB.
Main Methods:
- A cohort of 270 sexually active men treated with PB was assessed.
- Erectile function was evaluated using the International Index of Erectile Function 5-item (IIEF-5) questionnaire before and after treatment.
- A mean follow-up of 36 months was conducted to assess changes in erectile function.
Main Results:
- A significant proportion of men experienced erectile dysfunction (ED) after PB, ranging from mild to severe.
- 73% of patients with pre-treatment IIEF scores above 12 showed a decline in erectile function.
- Age, pre-implant IIEF score, and prostate volume were identified as risk factors for ED.
- Median time to ED onset was 16 months, with faster onset in patients receiving androgen deprivation, those with diabetes, or aged over 55.
Conclusions:
- Prostate brachytherapy (PB) is frequently associated with the progressive development of erectile dysfunction (ED).
- A notable free interval often precedes the onset of ED, lasting several months.
- Understanding risk factors and timing of ED is crucial for patient counseling and management post-PB.

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.

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
