Summary
Patients with primary premature ejaculation (PPE) have a higher average number of dorsal penile nerves (7.16 branches) compared to healthy individuals (3.55 branches). This suggests excessive dorsal penile nerves may increase sensitivity, impacting PPE.
Area of Science:
- Anatomy
- Urology
- Sexual Health
Background:
- Clinical observations suggest variations in dorsal penile nerve counts in patients with primary premature ejaculation (PPE).
- The typical number of dorsal penile nerve branches is considered to be two.
Purpose of the Study:
- To evaluate the number and distribution of dorsal penile nerves in healthy Chinese adults.
- To compare nerve counts between healthy individuals and patients diagnosed with PPE.
Main Methods:
- Autopsy examination of 38 adult specimens to count dorsal penile nerve branches.
- Surgical assessment of dorsal penile nerve distribution in 128 patients with PPE.
Main Results:
- The average number of dorsal penile nerves in autopsy specimens was 3.55 branches.
- In patients with PPE, the average number of dorsal penile nerve branches was significantly higher at 7.16.
- Nerve distribution patterns varied, with most branches located dorsally, but some communicating or ventrally extending branches were noted.
Conclusions:
- The average number of dorsal penile nerves is higher in patients with PPE than in healthy individuals.
- Excessive dorsal penile nerves may contribute to PPE by increasing penile sensitivity.
- Findings provide topographic data relevant for potential PPE treatments.

01:17Male Sexual Response: Erection & Ejaculation
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.

01:29Penis
The penis serves a dual role in sexual reproduction and urination. It consists of three main regions: the glans penis, the body, and the root, each with distinct functions and unique anatomical features.
Anatomy of the Penis
The glans penis, or the head, is the terminal part of the penis and houses the external urethral orifice, the exit point for urine and semen. Covered by the prepuce, or foreskin, the glans is noted for its sensitivity and plays a key role in sexual pleasure. The body of the...

01:15Sperm Transport
The journey of sperm from its origin to the point of ejaculation begins within the seminiferous tubules of the testis. Here, Sertoli cells produce fluid that propels non-motile sperm through a series of conduits, starting with the straight tubules leading to the rete testis. This interconnected network of tubules acts as the initial pathway for sperm, guiding them into the efferent ductules and then into the epididymis for maturation.

01:16Accessory Glands of the Male Reproductive System
The accessory ducts involved in sperm maturation and transportation include the epididymides, vasa deferentia, ejaculatory ducts, and urethra. These ducts play a critical role in the maturation, storage, and transportation of sperm from the testes to the urethra, where it is then released during ejaculation.
The epididymis is a small, comma-shaped organ located at the back of each testicle. The epididymis can be divided into three main parts: the head, body, and tail. The head of the epididymis...

01:20Disorders of the Male Reproductive System
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.

01:18Disorders of the Autonomic Nervous System
The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.
