Sperm Morphology in Neotropical Primates [PDF]
Animals, 2019 The morphological and morphometric characterization of spermatozoa has been used as a taxonomic and phylogenetic tool for different species of mammals. We evaluated and compared the sperm morphometry of five neotropical primate species: Alouatta caraya, Ateles belzebuth and Ateles chamek of family Atelidae; and Cebus cay (=Sapajus cay) and Cebus ...

Sperm morphology, sperm motility and paternity success in the bluethroat (Luscinia svecica). [PDF]
PLoS ONE, 2018 Postcopulatory sexual selection may select for male primary sexual characteristics like sperm morphology and sperm motility, through sperm competition or cryptic female choice.

Sperm morphology and sperm velocity in passerine birds [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2008 Sperm velocity is one of the main determinants of the outcome of sperm competition. Since sperm vary considerably in their morphology between and within species, it seems likely that sperm morphology is associated with sperm velocity. Theory predicts that sperm velocity may be increased by enlarged midpiece (energetic component) or flagellum length ...

Effect of competitive cues on reproductive morphology and behavioral plasticity in male fruitflies [PDF]
, 2015 Phenotypic plasticity will be favored whenever there are significant fitness benefits of responding to environmental variation. The extent and nature of the plasticity that evolves depends on the rate of environmental fluctuations and the capacity to ...

Hydrodynamic propulsion of human sperm [PDF]
, 2009 The detailed fluid mechanics of sperm propulsion are fundamental to our understanding of reproduction. In this paper, we aim to model a human sperm swimming in a microscope slide chamber.
