本文报告应用透射电镜观察体外阴道毛滴虫吞噬、消化人精子全过程的超微结构变化。虫体与精子共育１５～３０ｍｉｎ后，虫体粘附、包绕和吞噬精子，在胞质中形成吞噬泡（食物泡）；共育４５～７５ｍｉｎ，次级溶酶体（消化泡）中的精子被消化；９０～１０５ｍｉｎ后，消化过程结束，细胞质中多见残体（排泄泡）和空泡；１２０～１５０ｍｉｎ，虫体出现自噬现象或摄食。在吞噬与消化精子阶段，虫体的粗面内质网较丰富、高尔基体发达、氢化酶体数量较多。本研究进一步证实阴道毛滴虫具有较强的吞噬与消化的潜在能力，提示滴虫性阴道炎可能影响女性受孕的几率
This paper reports the use of transmission electron microscopy observed in vitro Trichomonas vaginalis phagocytosis, digestion of human sperm ultrastructure changes. After the larvae and sperm co-culture for 15 ~ 30min, the parasites adhere, surround and phagocytize the spermatozoa and form phagocytes (food bubbles) in the cytoplasm. After a total of 45 ~ 75min co-incubation with secondary lysosomes Of the sperm were digested; 90 ~ 105min after the end of the digestion, the cytoplasm more common debris (vacuoles) and vacuoles; 120 ~ 150min, parasites appear autophagy or feeding. In phagocytosis and digestion of sperm stage, parasites rough rich endoplasmic reticulum, Golgi developed, the number of hydrogenated body more. This study further confirmed Trichomonas vaginalis has a strong phagocytosis and digestion potential, suggesting that trichomonas vaginitis may affect the risk of female conception
