　　1.用进废退。美国南伊利诺伊大学医学院泌尿学教授托比亚斯·科勒博士表示，与身体其他部位一样，阴茎也需要经常锻炼。阴茎平滑肌需要经常在充血(勃起)时得到供氧维护。睡眠过程中，来自大脑的刺激会导致勃起。而相关神经受到损伤或者糖尿病导致神经或血管损伤会导致勃起困难。科勒博士表示，不经常勃起会导致阴茎组织弹性减弱，进而可使阴茎缩短1—2厘米。

　　2.阴茎也分“显性”和“隐性”。阴茎疲软时长度与勃起后长度之间没有任何关联。勃起后长度没有明显增加的阴茎被称为“显性阴茎”，勃起后长度增加很多的阴茎被称为“隐性阴茎”。性学专家阿尔弗雷德·金赛通过对上千名男性阴茎尺寸的测量发现，与非勃起状况阴茎较长的男性相比，阴茎较短男性勃起后长度能增加两倍。

　　6.阴茎极容易藏菌。阴茎皮肤及包皮极容易藏匿多种细菌。美国亚利桑那州菲尼克斯市基因组学研究院的研究人员，在阴茎包皮中共发现了42种独特的菌群。包皮环割后，阴茎携带菌群明显减少。完成于乌干达的一项研究发现，包皮环割可使艾滋病病毒(HIV)的感染率降低60%。因此为了自身及妻子健康，男性应经常清洗私处。
