When Microphallus pygmaeus Levinsen, 1881 was inoculated orally to laboratory mice, most specimens, failed to attach to the intestinal wall and passed out rapidly with the faeces. Those which did settle were distributed more or less evenly throughout the small intestine by 4 h after inoculation. By day 1 after inoculation the worms had developed to oviposition and most were found in the ileum. By 2 days after inoculation all worms were established, and they remained in this region where they grew and continued egg production with very little further mortality until day 6 after inoculation. Thereafter, gravid worms progressively detached and passed rapidly through the caecum, colon, and rectum with the faeces. All parasites had been voided by about day 12 inoculation. In spite of high mortality, distribution in the small intestine is also affected by the site of implantation.
1881年，莱文森描述的微小阴茎吸虫经口接种到实验小鼠体内时，大多数标本未能附着在肠壁上，很快随粪便排出。那些定居下来的标本在接种后4小时内或多或少均匀地分布在整个小肠中。接种后第1天，这些蠕虫已发育到产卵阶段，大多数位于回肠。接种后2天，所有蠕虫都已定居，它们留在这个区域生长并继续产卵，直到接种后第6天死亡率很低。此后，成熟的蠕虫逐渐脱离，迅速随粪便通过盲肠、结肠和直肠。到接种后约第12天，所有寄生虫都已排出。尽管死亡率很高，但在小肠中的分布也受植入部位的影响。
