Patient's question:
I am 45 years old, male, and was previously normal. Recently, I have experienced premature ejaculation, and my partner is also not satisfied. I want to know what causes premature ejaculation.Doctor's answer:
Hello, the causes of premature ejaculation are relatively complex and have not yet been fully clarified. It may be related to genetics, or it could be associated with an excess or deficiency of neurotransmitters in the brain. Currently, medications such as selective serotonin reuptake inhibitors (SSRIs) are used to inhibit the central nervous system to achieve therapeutic effects. Peripheral medications include topical anesthetics or anesthetic creams. Additionally, certain types of condoms can be chosen to improve symptoms.In patients with primary premature ejaculation, the branches of the penile dorsal nerve are more numerous than in normal individuals, and the excitability of the penile dorsal nerve is higher, with a lower vibration threshold. Particularly in the glans penis, the sensory and neural excitability is higher than in normal individuals, leading to a shorter reflex time for ejaculation during sexual intercourse and an increased tendency to induce premature ejaculation during the process.
