Abstract

BACKGROUND

Retrograde ejaculation can have anatomical, neurogenic, or pharmacological causes. Among these factors, malformation of the prostatic urethra is an uncommon cause.

CASE PRESENTATION

We describe a 29-year-old Han Chinese man with absence of his verumontanum combined with ejaculatory duct cysts, and no other cause for ejaculatory dysfunction. His verumontanum was replaced by a deep groove adjacent to his bladder neck, which could significantly influence bladder neck contraction. In addition, the large cysts in the ejaculatory duct could obstruct the anterior outlet of his prostatic urethra and prevent seminal fluid flow in an anterograde direction. There are few reports of retrograde ejaculation associated with congenital malformations of the posterior urethra. Malformations associated with bladder neck laxity and increased tone of the prostatic urethral outlet can contribute to retrograde ejaculation.

CONCLUSIONS

Malformation of the prostatic urethra is an uncommon cause of retrograde ejaculation, and can be difficult to treat.

摘要

背景

逆行射精可由解剖学、神经源性或药理学原因引起。在这些因素中，前列腺尿道畸形是一种不常见的原因。

病例介绍

我们描述了一名29岁的汉族男性，其精阜缺如并伴有射精管囊肿，且无其他射精功能障碍的原因。他的精阜被膀胱颈附近的一条深沟所取代，这可能会显著影响膀胱颈收缩。此外，射精管中的大囊肿可阻塞前列腺尿道的前出口，阻止精液向前流动。关于后尿道先天性畸形相关逆行射精的报道很少。与膀胱颈松弛和前列腺尿道出口张力增加相关的畸形可导致逆行射精。
