| 摘 要： | 波纹巴非蛤由雌性逆转为雄性时，其生殖腺雌性滤泡内卵细胞败育，逐渐退化分解吸收。同时，分布于滤泡壁上的原始精原细胞开始生长发育。残留的雌性生殖细胞与发育的雄性生殖细胞共同存在于滤泡腔内，即为波纹巴非蛤的雌雄间性过渡阶段。随着滤泡内卵细胞的退化吸收，精细胞与雄性泡逐渐形成。波纹巴非蛤雄性个体是由雌性个体通过性反转发育而来，这种性别的转化是双方向的。此外，波纹巴非蛤雌雄同体存在两种滤泡结构类型。

| Abstract: | In this paper, a detailed study on the histological structure changes in the gonad during P, (Paratapes ) undulata (Born) sex reversal from female to male was made by means of light microscope.During the natural sex reversal the female follicle ovas were degenerated, disintegrated and absorbed. At the same time, the spermatogonia on the follicle wall begin to multiply, and to become spermatogonium. Thus, the degenerated female germ cells and developed male germ cells settle in the same follicle sac.This is the stage of intersex development. With the degeneration and absorption of the follicle ovas, the spermatids and the male follicles were gradually formed. The male individual develops from sex - reversaling female.This sex transformation is in two directions. In addition, two types of the follicle morphologically of the hermaphroditism in the clam were discovered and examined. |
