The number of mitochondrion is more less than the endoplasmic reticulum, and the smooth endoplasmic reticulum is the main kind of the endoplasmic reticulum ; golgi bodies and lysosomes emerge in the secondary spermatocyte stage. finally, these organelles change into pre - acrosome vesicles which become acrosome at last. sinopotamon chekiangense during the spermatogenensis, chronmatins condense at different level until middle spermatid stage
在整個發生過程中細胞器數量較少，內質網數目在各細胞器中所佔比例最大，以滑面內質網為主，線粒體在初級精母細胞中最多，自次級精母細胞開始逐漸減少，高爾基體和溶酶體自次級精母細胞始出現，在發育過程中上述細胞器不斷分化，在精細胞階段形成前頂體腔，最後形成圓球形頂體。 -
Mitochondria and ribosomes are hard to see, and the ribosome are found to adhere on the surface of endoplasmic reticulum ; golgi body and lysosome do not exist, membranous ring emerges at the secondary spermatocyte stage. the organelles change into pre - acrosome vesicles at middle spermatid stage, and finally pre - acrosome forms acrosome. 2
浙江華溪蟹在生精細胞階段，染色質形態相似，呈不同程度凝集狀，核仁在精原細胞期出現;精細胞階段，染色質分化成纖絲狀和緻密塊狀，部分核質延伸入輻射臂內，整個核呈淺杯狀。
