The sooth beneath the taste roseas in the urethra and first description of neuro-morpho-chemical mechanism of penile erectile posture in males: an experimental study.

AIM: The morphologic mechanism of orgasmic sensation has not yet been understood. Taste roseas may be stimulated by fructose via pudendal nerves, which has not been studied yet.

METHODS

In this study, 27 male adult rabbits were used, which were divided into three groups: 5 as control; 5 as SHAM and 17 used as study group. We injected 0.2 cc of distilled water to SHAM and 0.2 cc of fructose solution to the study group of their urethral orifices, and examined the occurrence of penile erection. The relationship between erection and pudendal nerve ganglia and penile tissues was statistically compared.

RESULTS

In animals with high neuron density of pudendal ganglia, more erection phenomenon was observed than those animals with low neuron density. Interestingly, neuron density of pudendal ganglia was 9.243 ± 542 /mm3 in hypoactive and was 5.980 ± 463 /mm3 in non-active animals (p < 0.05).

CONCLUSIONS

The seminal fructose may stimulate taste roseas of the urethra and glans penis via pudendal nerves. The present study describes a new neuro-morpho-chemical mechanism of orgasmic sensation with its neurosurgical aspect.
