Effects of altered epididymal sperm transit time on sperm quality [PDF]
International Journal of Andrology, 2008 SummaryThe epididymal sperm transit time seems to have an important role in the process of sperm maturation, and it seems that alterations to the transit can harm the process. The aim of the present work was to evaluate the influence of altered sperm transit time through the epididymis on sperm parameters and fertility of rats, as well as the role of ...

Sperm allocation in relation to female size in a semelparous salmonid [PDF]
Royal Society Open Science, 2016 To maximize reproductive success, males have to adaptively tailor their sperm expenditure in relation to the quality of potential mates because they require time to replenish their sperm supply for subsequent mating opportunities.
