    26下孵化的小龜精巢皮質退化成為一層薄的白膜，髓質有許多睪丸管構成，管腔內有散落排列的精原細胞。
  7. Portunus, trituberculatus the spermatogonium exist in two different forms, the second form comes from the first one. during spermatogenesis, chromatins condense at different level. the nucleus changes into homogeneous since middle spermatid stage, and the nucleus extends into the radial arm

    三疣梭子蟹在生精細胞階段，染色質不同程度的濃縮凝集；在精細胞階段，核質呈均質狀，形成薄壁的圓球形核杯，部分核質延伸入輻射臂內。
  8. At the beginning, the cytoplasm is evently distributed, then it is polar - distribution and at last it only remains between the apical cap and the sperm nucleus. during the period of spermatogonium, chromatin in the nucleus is in the shape of conglomeration and the nucleus is big ( i. e. the proportion of the nucleus to cytoplasm is bigger than spermatocyte ). at the stage of primary spermatocyte, chromatin accumulates to sc complexity. the nucleus of the mature sperm takes the shape of a plate and filmentous chromatins exist freely in uncondensed nucleus

    精子發生過程中，細胞器由少到多，到最後解體；細胞質從均勻分佈，到精細胞期極性分佈，最後殘留于成熟精子的頂帽和精核之間；細胞核在精原細胞期，染色質異固縮，胞核大，即核質比大於后續的精母細胞；在初級精母細胞中，染色質凝聚為sc復合體，到成熟精子，精核呈碟狀，染色質呈絲狀游離于非濃縮的核中。
  9. The testis development stages are determined according to cell ' s morphological characteristics, its size and number and the varying extent of chromatic agglutination. the development of testis may be divided into five stages : ( 1 ) multiplication of spermatogonium ; ( 2 ) growth of spermatocytes ; ( 3 ) maturation of spermatocytes : ( 4 ) initial appearance of spermatozoa ; ( 5 ) complete maturation of spermatozoa ? the reproductive seasons cover from march to april

    可根據各期細胞大小、數量多少、核染色質凝聚程度等將精巢的發育時期劃分為精原細胞增殖期、精母細胞生長期、精母細胞成熟期、精子開始出現期、精子完全成熟期共5個時期。
