Why do men ejaculate prematurely?

Premature ejaculation is a male-specific disease. It means that the time a man can last during sex is too short. Normally, a man can last for about 20 to 30 minutes during sex. If the time is too short, it will lead to sexual disharmony between the couple and the male's sperm motility will be lower. This will also reduce the probability of pregnancy. So why do men have premature ejaculation?

The clinical manifestation of premature ejaculation is mainly premature ejaculation. Taking time as the standard: from the time the penis is inserted into the vagina to ejaculation, it is generally considered premature ejaculation if it is less than 2 minutes. Taking the number of twitches as the standard: if the penis is inserted into the vagina and twitches less than 10 to 30 times, it is premature ejaculation. Taking the reaction of the sexual partner as the standard: if the woman cannot reach orgasm in more than half of the sexual life opportunities during sexual activities, it can also be called premature ejaculation. Patients are often accompanied by anxiety, depression, dizziness, fatigue and other symptoms.

1. Specialist physical examination

This includes examination of male secondary sexual characteristics, penis, testicles and epididymis, and sometimes even requires prostate and seminal vesicle color Doppler ultrasound examinations to identify premature ejaculation or other sexual dysfunctions, especially underlying diseases related to erectile dysfunction.

2. Psycho-psychological analysis

Psychological analysis can be performed using the psychiatric personality test SCL-90-R, which helps to understand the patient's mental and psychological condition.

3. Neuroelectrophysiological examination

Using penile vibration sensitivity measurement, dorsal penile nerve evoked potential measurement, glans penile sensory evoked potential measurement, and bulbocavernous reflex latency measurement to measure changes in penile sensitivity threshold and other conditions helps to understand penile sensitivity and the function of sensory nerves.

4. Others

Routine urological examinations can determine whether there are other induced causes such as balanitis, prostatitis, seminal vesiculourethritis, etc. If necessary, sex hormone levels such as testosterone and prolactin can be tested.
