Penile nerves

The penis is the male reproductive organ, and it is common for the penis to have too many nerves. If there are too many nerves in the male penis, it will easily cause the penis to be more sensitive, which may easily lead to premature ejaculation or sexual dysfunction. It can be treated through surgery. Surgery can be used to cut off part of the nerve sensitivity and allow the penis to reach a normal state.

What to do if the penis is too nervous?

Considering that the dorsal penis nerves are more distributed, the sensitivity of the foreskin and glans is significantly increased, resulting in a decline in the quality of sexual life. First of all, it is recommended that you maintain a hygienic sexual life, drink more water, urinate more, and go to a professional urologist or andrologist to monitor the sensitivity of the glans. Through the numerical value, comprehensive analysis and judgment can be made. Surgery and physical therapy can be used.

Penile nerve block is a surgical procedure that cuts off part of the sensory nerves, which reduces the sensitivity of the glans penis, decreases the input of nerve impulses, and prolongs the time it takes for the nerves that control ejaculation to reach the excitement threshold.

In recent years, there have been reports both at home and abroad about the treatment of premature ejaculation with penile nerve block, which may have certain therapeutic effects, but its safety and long-term effects still need further research. At the same time, due to the complexity of the physiological process of ejaculation reflex, there are relatively few basic studies related to it, and the detailed mechanisms of many links are still unclear.

Therefore, the theoretical basis for this surgery is not sufficient. In addition, the number, length, and method of resection of the nerve branches need to be explored and summarized in subsequent clinical practice.

In short, this surgery is an invasive operation and there is still great controversy about the surgical effect and specific methods. The safety and long-term effectiveness are still uncertain, and it is far from the stage where it can be promoted. Therefore, doctors and patients must be cautious before choosing surgical treatment.

Anatomy

1. It is divided into three parts: root, body and head. The rear part is the root of the penis, which is attached to the inferior ramus of the pubic bone, the sciatic ramus and the urogenital diaphragm; the middle part is the body of the penis, which is cylindrical and hangs down in front of the pubic symphysis; the front part is enlarged as the glans penis, with a sagittal cleft at the tip of the head called the external urethral orifice, and there is a ring-shaped groove at the junction of the head and the body called the penis neck or coronal sulcus.

2. The corpus cavernosum of the penis is a cylinder with two tapered ends, one on the left and one on the right, located on the dorsal side of the penis. The left and right are tightly combined and extend forward, with the front end tapering and embedded in the depression on the bottom of the glans penis. The rear end of the corpus cavernosum of the penis is separated, called the crus penis, which is attached to the inferior pubic ventral branch and the sciatic branch of the pubic bones on both sides respectively. The corpus cavernosum of the urethra is located on the ventral side of the corpus cavernosum of the penis, and the urethra runs through its entire length. The middle part is cylindrical, with the front end bulging into the glans penis and the rear end bulging into the urethral bulb, located in the middle of the two crus penis and fixed on the fascia below the urogenital diaphragm. Each corpus cavernosum is wrapped with a thick fibrous membrane, called the tunica albuginea of ​​the corpus cavernosum.

The interior of the corpus cavernosum is composed of many corpus cavernosum trabeculae and cavities, which are actually sinus spaces connected to blood vessels. When these cavities are filled with blood, the penis becomes thicker and harder and erects; otherwise, it becomes soft. The three corpora cavernosa are covered with superficial and deep penile fascia and skin. The penis membrane is thin, soft and stretchable. The skin moves forward to the neck of the penis, forming a double-layered annular fold that wraps around the glans penis, called the foreskin of the penis, which turns back to the skin of the glans penis at the neck of the penis.

The cavity between the foreskin and the glans penis is called the foreskin cavity. On the midline of the ventral side of the glans penis, the skin fold connecting the foreskin and the external opening of the urethra is called the frenulum of the foreskin. If the foreskin is too long, too tight, or infected, it will cause pain during sexual intercourse. In young children, the foreskin is longer and covers the entire glans penis. As they age, the foreskin gradually retracts and the foreskin opening expands accordingly. If the foreskin covers the urethra but can be turned up to expose the external opening of the urethra and the glans penis, it is called foreskin is too long. When the foreskin opening is too small and the foreskin completely covers the glans penis and cannot be turned up, it is called phimosis. In both cases, inflammation may easily occur due to stimulation from dirt in the foreskin cavity, which may also be a factor in inducing penile cancer. Excess foreskin should be surgically removed to expose the glans penis.

Organizational structure

The blood supply to the penis comes from the dorsal penile artery, a branch of the external iliac artery. During sexual arousal, the three branches of the dorsal penile artery and its arterioles dilate, increasing blood flow; the arteriovenous communication branch is blocked, venous return decreases, and the cavernous sinus becomes congested, causing penile erection. The head of the penis has abundant nerve endings, so the frenulum of the penis, the coronary sulcus, and the area around the urethral opening are particularly sensitive to external mechanical stimulation. The afferent nerve of sensory sensation is the dorsal penile nerve. After reaching the low sexual response center of the sacral cord, the efferent parasympathetic nerve innervates the penile vascular smooth muscle and changes the vascular state. Pathological changes in the penile blood vessels and nerves can affect mating function.

Two natural states

1. When relaxed, it hangs below the pubic symphysis, with an average length of X=6.55, S=1.023, X±1.96S=6.55±2.046 (4.5-8.6) cm, a maximum of 10.6 cm, and a minimum of 3.7 cm; an average transverse diameter of X=2.57.S=0.255, X±1.96S=2.57±0.57 (2.06-3.08) cm, a maximum of 4.3 cm, and a minimum of 1.9 cm.

2. When erect, the penis forms an angle of 90° or more with the pubic mons with the pubic symphysis as the axis, and the length increases by 1 to 2 times compared to normal, and the volume and hardness increase accordingly. It is generally believed that the swelling rate of a smaller penis when flaccid is greater than that of a larger penis, so it is rare for a penis that is too small or too large to affect mating.
