Effects of altered epididymal sperm transit time on sperm quality
(Wiley-Blackwell, 2008-08-01)
The 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 ...

Comparison of apoptotic cells between cryopreserved ejaculated sperm and epididymal sperm in stallions
(2012)
The development of a reliable technique to freeze epididymal semen would provide a unique opportunity to preserve valuable genetic material from unexpectedly lost stallions. The aim of this study was to compare the apoptotic ...
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 ...

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 ...
Sperm motility in ocellate river stingrays: evidence for post-testicular sperm maturation and capacitation in Chondrichthyes
(Wiley-Blackwell, 2019-01-01)
Sperm maturation, as a process through which spermatozoa acquire the ability for motility activation and fertilization, is well-known for many groups of animals. This process takes place in a taxon-specific manner in ...
Angus sire field fertility and in vitro sperm characteristics following use of different sperm insemination doses in Brazilian beef cattle
(2020-04-15)
The primary objective was to determine if Angus bull fertility varied by number of sperm inseminated. A secondary objective was to characterize the potential impact of random variation on fertility using two identical sperm ...
Blood and seminal plasma concentrations of selenium, zinc and testosterone and their relationship to sperm quality and testicular biometry in domestic cats
(Elsevier B.V., 2014-11-10)
The aim of this study was to assess seminal plasma (SP) and serum concentrations of zinc (Zn), selenium (Se) and testosterone (T) in domestic cats and determine whether these are related to sperm quality and testicular ...
Physical and morphological characteristics of the first three jets of pêga jackasses sperm-rich fraction
(2016-01-01)
The first three jets of the sperm-rich fraction of Pêga jackasses were collected and assessed separately. Five fertile Pêga jackasses were used as semen donors and underwent fractionated semen collection, using an open ...
