Amastigote forms of Trypanosoma cruzi (Bolivia strain) were detected in the sex organs of male mice 15 days after inoculation. The presence of the parasite close to the lumen of the seminiferous tubules and mixed with spermatozoa in the lumen of the epididymal duct suggests the possibility of transmission of Chagas' disease through coitus. Morphological analysis of the vas deferens revealed structural alterations compatible with the early form of chagasic esophagopathy.
接种后15天，在雄性小鼠的性器官中检测到克氏锥虫（玻利维亚株）的无鞭毛体形式。寄生虫靠近生精小管腔并与附睾管腔内的精子混合存在，提示恰加斯病通过性交传播的可能性。输精管的形态学分析显示出与恰加斯病性食管病早期形式相符的结构改变。
