A short YouTube monologue by Anne Truong MD explaining that the parasympathetic nerves (which travel around both sides of the prostate) mediate erections, while penile sensation is carried by the pudendal nerve via a different pathway. The speaker notes that prostate enlargement, cancer, and procedures such as prostatectomy can involve or damage the parasympathetic erectile nerves because they lie adjacent to the prostate, potentially affecting erectile function.

Interestingly, the nerve that is responsible for the erection actually is the parasympathetic nerve, which actually goes around the prostate. On both sides of the prostate, it goes to the penis. But the nerve for the feeling of the penis comes from the pudendal nerve, which is from a different nerve pathway than the nerve that is responsible for erection. So that's why when you have an enlarged prostate or even prostate cancer and prostate procedures, procedures such as prostatectomy, where surgery to remove the prostate, the nerve that is responsible for erection in the penis, is located right next to the prostate. Oftentimes that gets involved as well.
