7. Dysfunction of the central 5-hydroxytryptamine system in the brain
(D) Clinical manifestations of premature ejaculation
There is no need to elaborate. Regardless of the type of premature ejaculation, it will have a great impact on the normal life of the couple, and both parties will be distressed by the lack of sexual satisfaction, which will often lead to marital tragedy in the long run.
(E) Diagnosis of premature ejaculation
1. Medical history. It is possible to understand the causes of premature ejaculation, which has certain guiding significance for its treatment.
(1) Past history. Acute or chronic diseases, surgery, trauma, history of medication, bad habits.

(2) Urinalysis. Routine urine, urine sediment, urine flow rate, etc.
(3) Prostate, semen examination.
(3) Neurological examination. The purpose is to distinguish between functional and organic premature ejaculation
(1) Penile vibration sensation measurement
It can evaluate the centripetal conduction function of the dorsal penile nerve and the excitability of the brain nerve center. This method is simple and inexpensive, and can be used as a screening test to help analyze the condition.
(2) Dorsal penile nerve somatosensory evoked potential measurement
By stimulating the dorsal nerve endings of the penis and recording the changes in brain waves, we can evaluate the centripetal conduction function of the dorsal penile nerve and the excitability of the brain nerve center. This method is more objective.
(3) Sacral reflex arc test
By stimulating the dorsal penile nerve, the response of the penile bulbocavernosus muscle is recorded.
4.Psychological examination
Psychological investigations are conducted through psychological scales and psychological counseling, and question and answer scores are used to determine whether premature ejaculation is psychological. At present, there is no specific examination method for premature ejaculation.
