We have studied penile structure in 300 specimens from cadavers, 3,000 patients undergoing general physical examination and more than 700 patients operated on for organic impotence. Special attention has been focused on the closure mechanism of the corpora cavernosa during erection. Venous outlets of the corpora cavernosa normally are situated only on the distal third of the ventral penile surface. A firm, lasting erection requires a tight albuginea of the corpora cavernosa, with perfect closure of the venous outlets. During life use of the penis or, eventually, misuse by repeated long-lasting, firm erections (high pressure in the corpora cavernosa) results in deterioration of the tightness of the albuginea, especially when the albuginea is thin (25 per cent of the cases). We have found that a leakage factor of the corpora cavernosa is the most frequent cause of organic impotence in aging men.
我们研究了300例尸体标本、3000例接受全身体检的患者以及700多例因器质性阳痿接受手术治疗的患者的阴茎结构。特别关注了勃起过程中海绵体的闭合机制。海绵体的静脉出口通常仅位于阴茎腹侧表面的远端三分之一处。坚挺持久的勃起需要海绵体白膜紧密，静脉出口完全闭合。在阴茎的日常使用过程中，或者最终因反复长时间坚挺勃起（海绵体内高压）而滥用时，会导致白膜紧密性下降，尤其是当白膜较薄时（25%的病例）。我们发现，海绵体渗漏因素是老年男性器质性阳痿最常见的原因。
