We investigated penile sensory levels in patients with primary premature ejaculation to determine whether there is an etiological basis for this condition.
Penile biothesiometry was performed in 120 patients with primary premature ejaculation without erectile dysfunction and neurological deficit, and in 66 normal potent male volunteers. Vibratory thresholds were recorded at the glans penis, penile shaft, scrotum and index finger using a biothesiometer.
On the glans penis and penile shaft the values in patients with premature ejaculation were significantly less than those in normal potent men (p < 0.001). In normal potent men an age dependency of biothesiometric parameters was noted, with a significant increase in vibratory threshold at the glans penis and penile shaft in older patients. However, in patients with premature ejaculation there were consistently decreased values without age dependency at the glans penis and penile shaft (p > 0.05).
Patients with primary premature ejaculation have penile hypersensitivity, which provides further implications for an organic basis of premature ejaculation.
我们研究了原发性早泄患者的阴茎感觉水平，以确定这种情况是否存在病因学基础。
对120例无勃起功能障碍和神经功能缺损的原发性早泄患者以及66名性功能正常的男性志愿者进行了阴茎生物感觉测量。使用生物感觉测量仪记录阴茎头、阴茎体、阴囊和食指的振动阈值。
早泄患者阴茎头和阴茎体的测量值显著低于性功能正常的男性（p < 0.001）。在性功能正常的男性中，生物感觉测量参数存在年龄依赖性，老年患者阴茎头和阴茎体的振动阈值显著增加。然而，早泄患者阴茎头和阴茎体的测量值持续降低，且不存在年龄依赖性（p > 0.05）。
原发性早泄患者存在阴茎超敏反应，这为早泄的器质性基础提供了进一步的依据。
