    目前,完全不能產生精子的非梗阻性無精子癥( non - obstmctiveazoospermia , noa )患者可採用卵胞質內圓形精子細胞注射( roundspermatidinjection , rosi )或長形精子細胞注射( elongatedspermatidinection , elsi )治療,精子細胞可從精液或從睪丸活檢組織中獲取。
  10. 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。
  11. 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。
