精子停滞Sperm Stasis · 附睾 · 雄性生殖系统 · NTP ntp-0501
诊断要点：精子停滞应记录并分级，如果其发生率和/或严重程度似乎与化学物给药相关，应在病理学叙述中讨论。
病变描述
精子停滞（sperm stasis）最常见于睾丸停止产生精子后，发生于附睾尾。精子被隔离在尾部管道内，呈强嗜酸性（Figure 1、Figure 2、Figure 3）。较近端的管道通常无精子。由阻塞性病变引起的精子停滞也可发生于附睾头和输出管。在 Figure 4 中，被隔离的精子呈嗜碱性。如果上皮衬里破损，精子进入间质，精子停滞可进展为精子肉芽肿（sperm granuloma）。
诊断与分级建议（NTP 共识）
精子停滞应记录并分级，如果其发生率和/或严重程度似乎与化学物给药相关，应在病理学叙述中讨论。当双侧附睾均受累时，应注明双侧，严重程度分级基于受累更严重的附睾。应在病理学叙述中注明与任何生精障碍的相关性，以助于解释。

Comment：
Sperm stasis is most commonly seen in the cauda epididymis following cessation of sperm production by the testis. Sperm become sequestered in the caudal ducts and are intensely eosinophilic ( Figure 1 , Figure 2 , and Figure 3 ). The more proximal ducts are generally empty of sperm. Sperm stasis also occurs in the caput and efferent ducts as a result of obstructive lesions. In Figure 4 , the sequestered sperm are basophilic. Sperm stasis may progress to sperm granuloma if the epithelial lining is breached and sperm gain access to the interstitium.
Recommendation：
Sperm stasis should be recorded and graded and should be discussed in the pathology narrative if the incidence and/or severity appears to be related to chemical administration. Bilateral should be indicated when both epididymides are involved, with severity grade based on the more severely affected epididymis. Correlation with any spermatogenic disturbances should be noted in the pathology narrative to aid interpretation. Pagination Figure 1 of 4 Next page › Epididymis - Sperm Stasis.
