Six normal males underwent both penile vibratory stimulation and masturbation in order to compare the quantity and quality of semen produced by each method. There was no significant difference in the quantity and quality of the ejaculates produced by vibratory stimulation of the penis and masturbation. In addition, biochemical analysis of the seminal fluid collected by both procedures revealed similar values between all specimens for nine organic constituents, seven inorganic constituents and seven metabolic enzymes. None of the subjects demonstrated retrograde flow of semen. These findings indicate that vibratory stimulation is a 'physiological' means of inducing ejaculation, and can produce semen of normal quality.
六名正常男性接受了阴茎震动刺激和手淫，以比较每种方法产生的精液的数量和质量。阴茎震动刺激和手淫所产生的射精量和质量没有显著差异。此外，通过这两种方法收集的精液的生化分析显示，所有样本中九种有机成分、七种无机成分和七种代谢酶的值相似。没有受试者表现出精液逆流。这些发现表明，震动刺激是诱导射精的一种“生理性”手段，并且可以产生正常质量的精液。
