... as the mucus and embedded gland content dissolve into the water. To test the importance of gland content on sperm function in Pomatoschistus minutus , a marine fish with external fertilization, we used a paired experimental design, with spermatozoa tested with and without sperm-duct gland content mixed...

... the mechanisms of spermatozoa movement. In this study, we described the composition of the seminal fluid (osmotic pressure, pH, and ions) and investigated the roles of these factors and salinity in initiating spermatozoa movement in the Pacific oyster, Crassostrea gigas . The acidic pH of the gonad (5.82±0.22...

...Quynh Thu Nguyen; Ulrike Wallner; Marion Schmicke; Dagmar Waberski; Heiko Henning ABSTRACT Mammalian spermatozoa utilize ATP as the energy source for key functions on the route to fertilization. ATP and its precursor nucleotides ADP and AMP are regularly investigated in sperm physiology studies...

... female Gpi1 −/− ↔ Gpi1 c/c chimaera were functional and provided preliminary evidence that one male putative Gpi1 −/− ↔ Gpi1 c/c chimaera produced functional spermatozoa from homozygous Gpi1 −/− null germ cells. Although the male chimaera was almost certainly Gpi1 −/− ↔ Gpi1 c/c , this part of the study...
