In the literature the determination of the vibration sensitivity threshold of the penile glans by means of biothesiometry has been introduced as a cost-effective office test for the evaluation of penile neuropathy in impotent men. At our facility we have gained extensive experience with neuro-urophysiological tests for the evaluation of penile innervation. These neuro-urophysiological tests have the disadvantage of complexity, invasiveness and time consumption. In our study both methods were compared in 31 impotent patients. The results showed that penile glans biothesiometry yields consistent results when measurements are repeated during 1 session. However, no relationship was found between the outcome of penile glans biothesiometry and neuro-urophysiological tests of the dorsal penile nerve, which is probably due to the fact that vibration is not an adequate stimulus to the skin of the penile glans that contains free nerve endings (that is pain receptors) only, and hardly any vibration receptors. We conclude that biothesiometric investigation of penile glans innervation is unsuited for the evaluation of penile innervation and cannot replace neuro-urophysiological tests.
在文献中，通过生物感觉测量法测定阴茎头的振动敏感性阈值已被引入，作为评估阳痿男性阴茎神经病变的一种经济有效的门诊检查方法。在我们的机构，我们在用于评估阴茎神经支配的神经泌尿生理学检查方面积累了丰富的经验。这些神经泌尿生理学检查具有复杂、侵入性和耗时的缺点。在我们的研究中，对31例阳痿患者的两种方法进行了比较。结果表明，在同一疗程中重复测量时，阴茎头生物感觉测量法可得出一致的结果。然而，未发现阴茎头生物感觉测量法的结果与阴茎背神经的神经泌尿生理学检查结果之间存在关联，这可能是因为振动对于仅含有游离神经末梢（即痛觉感受器）且几乎没有振动感受器的阴茎头皮肤而言并非适当的刺激。我们得出结论，阴茎头神经支配的生物感觉测量研究不适用于评估阴茎神经支配，不能替代神经泌尿生理学检查。
