Fine structure of the spermatozoa of Crassostrea gigas (Mollusca, Bivalvia) We describe sperm ultrastructure and acrosome differentiation during spermiogenesis in Crassostrea gigas (Mollusca Bivalvia). The sperm cell is a uniflagel... MG Bozzo,E Ribes,E Sagrista,... - 《Molecular Reproduction & De...

The spatial association of the sperm cells and vegetative nucleus in the pollen grain ofBrassica In mature viable pollen of Brassica oleracea , the pair of sperm cells and the nucleus of the vegetative cell are linked to form a structured unit we term ... C Dumas,RB Knox,T Gaude - 《Pr...
we solved the in-cell structure of mouse sperm DMT at 4.5–7.5 Å resolutions, and built its model with 36 kinds of MIPs in 48 nm periodicity. We identified multiple copies of Tektin5 that reinforce Tektin bundle, and multiple MIPs with different periodicities that anchor the Tektin bun...
and a sperm pump20,21,22. The spermathecal reservoir wall comprises two simple epithelial cell types with a cuticle lining, columnar epithelia in the hilar region of the reservoir near the opening of the spermathecal duct, and squamous epithelia in the distal region. Ultrastructural observations ...
Originally published in 2006, this is a comprehensive and definitive account of the human male gamete. The volume summarizes many unique and revealing characteristics of the sperm cell. It provides a detailed overview of human sperm production, maturation and function, and looks at how these process...
