  1. 1. spermatogenesis spermatogenesis can be devided into five stagesrspermatogonium, primary spermatocyte, secondary spermatocyte, spermatozon and sperm

    精子發生精子發生可分為精原細胞、初級精母細胞、次級精母細胞、精細胞、精子五個階段。
  2. The nucleus has two forms at the middle spermatid stage : fibrous one and condensed one. the nucleus extends into the radial arm. the number of organelles keeps increasing until secondary spermatocyte stage

    與已有的報導不同的是，我們發現精原細胞分為兩類，其中i類精原細胞經過分化形成n類精原細胞。
  3. According to the changes of the structure of chromatin and the morphology of cell, the process of the typical spermatogenesis of cipangopaludina chinensis can be divided into five stages : spermatogonium, primary spermatocyte, secondary spermatocyte, spermatid and mature sperm

    中國圓田螺典型精子發生時，根據染色質和細胞形態的變化，可將其發生分為以下五個時期：精原細胞、初級精母細胞、次級精母細胞、精細胞和成熟精子。
  4. Nucleoli do not emerge in this process. the number of the organelles increase until secondary spermatocyte stage. mitochondria accumulate together, merging together with lysosomes and golgi bodies at the early spermatid stage, and finally the lamellar structure is formed, which forms the acrosome at last

    在精子發生過程中，線粒體、內質網和核糖體逐漸增多，其中線粒體數目在次級精母細胞階段達到頂峰，並形成線粒體區，精細胞早期核內出現膜性泡結構，同時次級溶酶體與高爾基體大量存在，這些細胞器共同形成片層復合體，並參與頂體的形成。
  5. 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。
  6. 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。
  7. Nucleoli exist from spermatocyte stage to early spermatid stage. in this process, the numbers of ribosomes, mitochondrions and endoplasmic reticulums increase until secondary spermatocyte stage, golgi apparatus emerges at the secondary spermatocyte stage, and then, these organelles change into lamellar complex which finally forms the acrosome

    核糖體，線粒體和內質網等細胞器數量逐漸增多，到次級精母細胞階段達到最大，在形成精子的過程中，上述細胞器與高爾基體及膜性泡共同分化或參與形成片層小體，並參與頂體的形成。
