All types of prostate cancer treatment can cause erectile dysfunction. In the course of removing the cancerous prostate gland, due to their proximity, the nerves responsible for erection are often damaged.

Hormonal therapy will cause lack of desire and arousal as well as the inability to obtain a full erection.
