有性生殖在E.秀丽隐杆线虫在实验室培养中进行了详细的研究，特别是关于配子之间的接合和消失的菌落形成。通过改变培养基诱导雌雄配子融合。雄配子的前端，包括鞭毛基部，进入雌配子的前部区域。2个原生质体的融合从侧面和后面进行。雄配子在鞭毛基部有一细长的细胞质突起。这种结构以前没有在Eudorina的雄配子中描述过，可能参与了胞浆融合。一个双鞭毛虫细胞从萌发的合子中游出，并分泌一种凝胶状的包膜。然后，它分裂形成凝胶状包膜内的消失的菌落，在菌落形成过程中，通过从原始消失的细胞中保留完整的2个鞭毛移动。
Sexual reproduction in E. elegans Ehr. was studied in detail in laboratory cultures, with particular regard to conjugation between gametes and gone colony formation. Male and female gametes fused after being induced by changing the medium. The anterior end, including the flagellar base, of the male gamete entered the anterior region of the female gamete. Fusion of the 2 protoplasts proceeded laterally and posteriorly. The male gamete bore a slender cytoplasmic protrusion at the base of the flagella. This structure has not been previously described in the male gamete of Eudorina, and may participate in plasmogamy. A biflagellate gone cell swam from the germinating zygote and secreted a gelatinous envelope. It then divided to form a gone colony within the gelatinous envelope, which moved during colony formation by means of the 2 flagella which were retained intact from the original gone cell.
