The human pinworm Enterobius vermicularis is normally found within the human gastrointestinal tract. Pregnant females migrate out of their host's anus at night to lay their eggs perianally. As a consequence of this nocturnal migration some worms find their way into adjacent orifices, most commonly the female genitourinary tract, producing irritative symptoms such as vulvovaginitis. A case of pinworm infestation of the uterus presented as postmenopausal bleeding.
人体蛲虫（蠕形住肠线虫）通常寄生于人体胃肠道内。怀孕的雌虫会在夜间爬出宿主肛门，在肛周产卵。由于这种夜间迁移，一些蠕虫会进入相邻的孔窍，最常见的是女性泌尿生殖道，从而产生诸如外阴阴道炎等刺激性症状。一例子宫蛲虫感染表现为绝经后出血。
