Patient's question:
After neurosurgery, why does it cause difficulty in achieving an erection or a firm state? Many people go for nerve repair.Doctor's answer:
From a principle, the dorsal penile nerve blockage technique merely reduces the sensory sensitivity of the penis. However, a man's erectile function primarily depends on the coordination of the penile arterial and venous blood vessels, as well as the amount of blood ultimately perfused into the corpus cavernosum within a unit of time. Therefore, there is no direct relationship between the two. However, with the same level of erection strength, due to the decreased sensory sensitivity, the psychological perception of the erection strength may feel less than before. This is merely a perceptual misjudgment.
