Spermatogenesis in a parthenogenetic type of P. westermani (Kerbert 1878) called P. pulmonalis (Baelz 1880) throughout this study, was observed by light microscopy (LM), scanning (SEM), and transmission (TEM) electron microscopy. During spermatogenesis, most of the cells became degenerated or malformed as a result of aberrations during spermatogenesis. Vacuolated cells were often found in the testicular lumen. In some nuclei of spermatocytes, synaptonemal complexes were formed and this indicated that some pairing of homologous chromosomes did occur, but only rarely. Cytophores in some rosettes were broken down into small fragments and the cells separated from each other. Norman spermatozoa were very rarely found in the testis and never in the seminal receptacle, where egg and vitelline cells were present instead. Throughout spermatogenesis, Golgi complexes, mitochondria, ribosomes, and endoplasmic reticulum were not abundant, and this suggested that cell activities and protein synthesis were greatly reduced.
在本研究中，通过光学显微镜（LM）、扫描电子显微镜（SEM）和透射电子显微镜（TEM）观察了一种孤雌生殖类型的卫氏并殖吸虫（Kerbert，1878年），即肺并殖吸虫（Baelz，1880年）的精子发生过程。在精子发生过程中，由于精子发生过程中的畸变，大多数细胞发生退化或畸形。在睾丸管腔中经常发现空泡化细胞。在一些精母细胞核中，形成了联会复合体，这表明同源染色体确实发生了一些配对，但非常罕见。一些玫瑰花结中的细胞柄分解成小碎片，细胞彼此分离。在睾丸中很少发现正常精子，在精囊（其中存在卵子和卵黄细胞）中从未发现。在整个精子发生过程中，高尔基体、线粒体、核糖体和内质网不丰富，这表明细胞活动和蛋白质合成大大减少。
