Variability in sperm form and function in the context of sperm competition risk in two Tupinambis lizards
(Wiley, 2014-10)
In polyandrous species, sperm morphometry and sperm velocity are under strong sexual selection. Although several hypotheses have been proposed to explain the role of sperm competition in sperm trait variation, this aspect ...
Effect of short-term storage on sperm function in Patagonian blenny (Eleginops maclovinus) sperm
(ELSEVIER SCIENCE BV, 2017)
Chemotactic selection of frozen-thawed stallion sperm improves sperm quality and heterologous binding to oocytes
(Elsevier Science, 2020-10)
The successful use of assisted reproduction techniques (ART) depends in part on the sperm physiological status. Several sperm selection procedures have been applied to improve quality of sperm population when using the ...
Sperm competition and reproductive mode influence sperm dimensions and structure among snakes
(Wiley Blackwell Publishing, Inc, 2009-10)
The role of sperm competition in increasing sperm length is a controversial issue, because findings from different taxa seem contradictory. We present a comparative study of 25 species of snakes with different levels of ...
The oviductal sperm reservoir in domestic mammals
(Facultad de Ciencias Veterinarias, Universidad Austral de Chile, 2005)
Evaluation of different doses of mashua (Tropaeolum tuberosum) on the reduction of sperm production, motility and morphology in adult male rats.
(Wiley, 2012)
Mashua is an edible-tuber crop that grows in the Andean region. Folk medicine describes the use of mashua to reduce reproductive function in men. The present study aimed: (i) to determine whether different doses of mashua ...
Cytoplasmic droplet acting as a mitochondrial modulator during sperm maturation in dogs
(2017-06-01)
Motility acquisition during sperm maturation and passage through the epididymis is closely related to mitochondrial function and appears to occur in parallel with cytoplasmic droplet (CD) migration. However, such mechanism ...
Functional insights into the role of seminal plasma proteins on sperm motility of buffalo
(2018-08-01)
The objective of the present study was to describe the proteins from the seminal plasma of buffalo and correlate these proteins with sperm motility. Ejaculates from sixteen Murrah buffalo were used. Semen collection was ...
