Complex interactions between sperm viability and female fertility
(Nature Publishing Group, 2019-12)
Sperm viability is a major male fitness component, with higher sperm viability associated with enhanced sperm competitiveness. While many studies have focussed on sperm viability from the male fitness standpoint, its impact ...
Tritrichomonas fetus extracellular products decrease progressive motility of bull sperm
(Elsevier B.V., 2010-01-01)
Tritrichomonas fetus causes infertility and abortion in cattle; however, there is scarce information regarding the susceptibility of bovine sperm to this parasite. The objective of this study was to analyze in vitro the ...
Effect of Storage Time and Temperature of Equine Epididymis on the Viability, Motion Parameters, and Freezability of Epididymal Sperm
(2013-03-01)
The recovery of sperm from the epididymal cauda may be the last chance to obtain genetic material when sudden death or serious injuries occur in valuable stallions. However, the lack of technical knowledge regarding the ...

Copulatory behaviour increases sperm viability in female spiders
(Wiley Blackwell Publishing, Inc, 2020-09-20)
One remarkable reproductive feature in animals with internal fertilization is a reduction in sperm viability over time in females. Whether this reduction is driven by male-male competition and/or cryptic female choice is ...
Cooling of ejaculated and epididymal stallion sperm
(2013-09-03)
After a serious injury or sudden death, epididymis cauda sperm recovery and cryopreservation may present as the last opportunity to obtain genetic material from a valuable stallion. This study evaluated the viability of ...
