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 ...
Freezing of stallion epididymal sperm
(Elsevier B.V., 2008-09-01)
Inseminations with frozen-thawed epididymal sperm have resulted in low-pregnancy rates of mares. If fertility of epididymal sperm could be improved, it would help to preserve genetic material from stallions that have ...

Relationship between DNA damage and sperm head birefringence
(Elsevier B.V., 2011-06-01)
Birefringence or double refraction is the decomposition of a ray of light into two rays when it passes through an anisotropic material such as quartz. Sperm cells have been demonstrated to be optically anisotropic. The ...
Sperm selection criteria: is there a relation between motile sperm organellar morphology examination (MSOME) and sperm birefringence?
(Oxford University Press, 2010-06-01)
Sperm Organelle Morphologic Abnormalities: Contributing Factors and Effects on Intracytoplasmic Sperm Injection Cycles Outcomes
(Elsevier B.V., 2011-10-01)
OBJECTIVE To (1) analyze possible relationships between motile sperm organelle morphology examination (MSOME) and sperm chromatin status, aneuploidy incidence, and patient's age; (2) determine the effects of sperm morphologic ...
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 ...
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 ...
