摘要
以犬为模型对会阴肌在阴茎勃起中的作用进行研究。结果显示阴茎基础海绵体压为：１．１５±０．３５ｋＰａ，单独刺激盆神经时，会阴肌不收缩时阴茎海绵体压为１０．３６±２．３７ｋＰａ。单独刺激阴部神经时，阴茎海绵体压为：３．８±１．１４ｋＰａ。联合刺激二神经，会阴肌收缩最强时阴茎海绵体压可达４６．３３±１６．５２ｋＰａ，阴茎达到硬勃起期，可见会阴肌及阴部神经是增加阴茎勃起硬度的重要因素，盆神经是阴茎勃起的基础。
Twenty-one male healthy dogs weighting from 15to 20kg were used to investigate the role of perineal muscles in penile erection.The basic introcorporeal pressure was 1.15±0.35kpa. With pelvic nerve stimulation,penile erection was evoked and the intracorporeal pressure was 10.36±2.37kpa.With pudendal nerve stimulation alone no penile erection occurred and the ICP was 3.80±1.14kpa.When both the pelvic and the pudental nerve were stimulated,there was a significant increase of ICP (46.33±16.52kpa).The results demonstrated the perineal muscles did participate in the mechanism of penile rigidity.
