How many dorsal penile nerves are there?

Generally speaking, dorsal penile nerve surgery is a very common surgery in the treatment of urology. However, this surgery has basically been performed in private hospitals, and the results are not particularly ideal. Under normal circumstances, the main nerves of the dorsal penile nerve of an adult male are about 3 fingers and 4 fingers. If there is a problem with the male penis, it is necessary to go to a professional hospital for testing.

In recent years, studies have shown that penile hypersensitivity or excessive excitability of the penile sensory nerve is one of the causes of premature ejaculation. Based on this theory, if the sensitivity of the penis is reduced by cutting off part of the dorsal penile nerve, the purpose of treating premature ejaculation may be achieved. In 1993, Tullii et al. reported the treatment method of dorsal penile nerve block (resection). This operation is an invasive operation, and there is great controversy about the surgical effect and specific method. Its safety and long-term effectiveness are still uncertain, and it is far from the stage where it can be promoted.

This surgery requires strict control of indications and is only suitable for married patients with extremely sensitive penises and premature ejaculation. The patient must have already received long-term medication, psychological, and behavioral treatments with little effect. At the same time, professional measurements of the penis are required before the surgery, and then a comprehensive judgment is made after obtaining objective data. Specifically, the surgical object must meet the following conditions at the same time:

1. Normal erectile function;

2. Married or with a fixed sexual partner, and having regular sexual life for >1 year;

3. Those with severe premature ejaculation;

4. No other organic factors;

5. Normal psychological quality;

6. Applying local anesthetic to the penis is effective

7. Wearing a condom is effective;

8. Those who have not responded to conventional behavioral therapy for more than 2 months;

9. Those who are generally 40 years old but have a strong desire for surgery.

In addition to the common complications such as infection, bleeding, and incision dehiscence, if too many branches of the dorsal penile nerve are cut during dorsal penile nerve block, it is easy to cause more complications, such as penile numbness and erectile dysfunction (ED). Generally speaking, cutting off some branches of the dorsal penile nerve does not affect erectile function, but it may cause penile numbness and obvious lack of sensation, which will reduce the function of penile reflex erection and affect penile erectile function. Because elderly men are prone to ED, this surgery is not suitable for the elderly or patients with premature ejaculation who have ED.
