Spermiogenesis and ultrastructure of spermatozoon of Nicolla wisniewskii (Digenea, Opecoelidae), an intestinal parasite of Salmo trutta, were studied by electron microscopy. Spermiogenesis follows the ...

A collaborative team of researchers from the National Institute for Basic Biology, the University of Tokyo, and Gunma University in Japan reported that in the liverwort Marchantia polymorpha, the ...

The red palm weevil (RPW), Rhynchophorus ferrugineus Olivier (Coleoptera: Curculionidae), is a pest that is rapidly spreading across the globe. Here, the ultrastructure of R. ferrugineus ...

In a recent study published in eLife, a group of researchers investigated the Role of Cylicins in Spermiogenesis and Male Fertility in Mice and Humans through Clustered Regularly Interspaced Short ...

During spermiogenesis, the mitochondrial number is reduced to one through fission and autophagic degradation, and subsequently increased to two through fission of the anterior mitochondrion. Other ...
