Spermatogenous that developed synchronizing distributed in mass 同步发育的性细胞群成团分布。
2.
The temination " of the deferent duct got into cloacal chamber a as apical segment . 1 . in ivtestis , seminiferous epithelium consisted of spermatogenous and sustentacular cell 在期精巢内，精细管包含有精原细胞、初级精母细胞、少量精子细胞和支持细胞。
3.
The damages of monocrotophos on tnicrostructure of testis were that it caused the deficiency of ground membrane , hypertrophied leydig cell and spermatogenous . besides , the y - gtp activity was inhibited by monocrotophos 久效磷对金鱼精巢组织结构的破坏主要表现为：精小叶基膜断裂； leydig氏细胞出现肥大现象；精原细胞膨胀。
4.
Sustentacular cell was at the exterior margin of spermatogenous . in v testis , seminiferous epithelium had spermatozoon , spermatid and sustentacular cell . the sustentacular cell was fat and full of particle 支持细胞位于性细胞团的外缘，对生精细胞起支持和营养作用;在v期精巢内，精细管由大量的精子、少量的精子细胞和支持细胞构成。
5.
In spermatogenous cell , we could find dilated cytolemma , dilated nuclear membrane and fused crista of mitochondria . most of the sperm ' s cellular membrane dissolved and broke down into pieces . the central granule and mitochondrion showed little dissolving 久效磷可以使金鱼精子细胞质膜溶解，出现间断性断裂;有的精子头部变形，顶部出现凹陷;少量精子颈部中心粒复合体溶解;精子颈部线粒体有溶解现象，精子尾部的膜结构断裂。
6.
The results suggested that monocrotophos had not only environmental estrogen effects , but also reproductive toxicity . monocrotophos could destroy the membrane systems of three kinds of pituitary secretary cell , spermatogenous cell and sperm . in three kinds of pituitary secretary cell , nuclear membrane and endoplasmic reticulum showed dilation , and endoplasmic reticulum even exhibited fusion under exposure in high concentration 久效磷对精原细胞的损伤最为严重，细胞膜和核膜水肿，高浓度暴露组的细胞膜和核膜溶解，线粒体的崎也有溶解现象;但久效磷对精母细胞和精子细胞的损伤并不明显，主要表现为膜系统的轻微水肿。
