Abstract
RESUMO O objetivo deste trabalho foi avaliar a recuperação de espermatozoides epididimários de cães castrados, utilizando as técnicas de fluxo retrógrado (FR) e flutuação (FL) em diluidor Tris-gema, antes e após a criopreservação. Foram coletados 30 complexos testículo-epididímos (CTE), sendo 15 para FR e 15 para FL, e, logo após a recuperação dos espermatozoides, foram analisadas as alterações morfológicas nessas células espermáticas. Após a adição do diluidor, foram avaliados os parâmetros de motilidade total (MOT) e vigor (V) espermáticos. O sêmen pós-criopreservado foi submetido ao teste de termorresistência nos tempos T0, T30, T60 e T90 minutos, além da avaliação das membranas plasmática e acrossomal por sondas fluorescentes. Não houve diferença estatística entre as técnicas quanto à MOT e ao vigor no sêmen diluído (FR-MOT: 82,3% e V: 3,4; FL-MOT: 79,6% e V: 3,2) e pós-criopreservado (FR-MOT: 34% e V: 2,8; FL-MOT: 30% e V: 2,7). A partir do T30, houve diferença significativa quanto à MOT e ao vigor nas técnicas utilizadas, e o tempo também prejudicou o acrossoma espermático a partir do T30. Conclui-se que as técnicas de recuperação de espermatozoides epididimários de cães castrados, testadas neste trabalho, podem ser utilizadas para refrigeração e criopreservação de sêmen.

Abstract
In order to add information to physiology of sperm maturation and help to underline future antioxidant supplementation treatment to epididymal sperm, the aim of this study was to evaluate susceptibility of caput, corpus and cauda epididymal sperm to different reactive oxygen species (ROS) in dogs. Epididymal sperm was separately collected from each segment (caput, corpus and cauda) and subjected to 4 different ROS-challenges: superoxide anion, hydrogen peroxide, hydroxyl radical, malondialdehyde (MDA) or maintained as control. After 30 min of incubation in each ROS, sperm was evaluated for sperm kinetics, plasma and acrossomal membrane integrity, mitochondrial activity and resistance to oxidative stress. Decreased total and progressive sperm motility and rapid velocity at epididymal corpus occurred after exposure to hydrogen peroxide, hydroxyl radical and MDA. However, for cauda epididymis, hydrogen peroxide and malondialdehyde promoted higher deleterious effect regarding sperm motility and velocity. Only at cauda epididymis MDA decreased sperm mitochondrial activity index and no kinetics alterations (motility or velocity) occurred after exposure to superoxide anion in corpus and cauda epididymis. In conclusion, corpus and cauda epididymal sperm are highly susceptible to deleterious effect of hydrogen peroxide, malondialdehyde and hydroxyl radical. In addition, epididymal canine sperm is relatively resistant to superoxide anion damage.

Abstract
In this study, sperms collected from the right and left cauda epididymis were grouped into having canine prostatic fluid (PF) sensitization or not diluted with egg yolk Tris-fructose citrate extender, and stored at 4°C. The necessity of canine PF in cooled preservation was determined by elucidating the sperm quality after the storage. As a result, while there was no difference among all groups up to 48 hr of storage, after storage for 96 hr and more, a significantly lower sperm motility was observed in the group without being sensitized to PF than the groups with being sensitized to PF (p < .05, p < .01). Although sperm abnormality increased in all groups with increased storage time, the group without being sensitized to PF showed significantly higher sperm abnormality than did the groups with being sensitized to PF after storage for 24 hr and more (p < .01). From these findings, we concluded that PF was necessary for the cooled preservation of the canine sperm because these sperms were protected from any effects of low temperatures by being sensitized to PF.

Abstract
Background During sperm maturation, there is a reorganization of fatty acids from plasmatic membrane of the spermatozoa, which allows higher membrane integrity and acquisition of sperm motility. However, the fatty acid profile during sperm maturation remains unclear in dogs. Thus, the aim of this study was to identify the fatty acids from the epididymal spermatozoa and plasma during the sperm maturation, and observed changes in the motility and plasmatic membrane parameters. Twenty one adult dogs were used, subsequently to bilateral orchiectomy and epididymal storage, sperm samples were collected from the different segments of the epididymis. Samples were evaluated for conventional microscopy, computer-assisted motility analysis, sperm plasma membrane permeability and the fatty acid analysis (lipids were extracted, transmethylated and analyzed by chromatography). Results Caput and corpus sperm showed lower values for the motility variables evaluated and plasmatic membrane integrity, indicating different levels of the fatty acids organization. Saturated, monounsaturated and polyunsaturated fatty acids were in higher concentrations in the spermatozoa from epididymis cauda. Highlighting the presence of caprylic, stearic and docosahexaenoic acids. Conclusions These findings demonstrate the influence of the fatty acid profile during sperm maturation, assigning physical and chemical changes in sperm cells, essential for fertilization.

Abstract
The hidden treasure represented by epididymal spermatozoa has great potential in the current reproductive technologies in dogs. In case of azoospermia or when a donor male accidentally dies or undergoes orchiectomy, the retrieval of epididymal spermatozoa opens new possibilities to generate progeny. Spermatozoa can be collected by different techniques from ex vivo or in vivo testicles and can be cryopreserved for a future use. Freeze tolerance of canine epididymal spermatozoa seems lower than that of ejaculated spermatozoa; however, puppies were born after artificial insemination with frozen epididymal semen, other than with fresh and chilled. Even though several aspects need to be further investigated, advances have been recently made in the use of epididymal spermatozoa in assisted reproduction in dogs.

Abstract
Canine epididymal sperm was collected from the cauda epididymis using 2
different methods (flushing and mincing) to compare the qualities (the percentage of
progressively motile, viable, morphologically abnormal, immature and intact acrosomes)
before and after freezing and thawing. No significant difference was noted in the quality
of the cauda epididymal sperm immediately after collection and after freezing-thawing
between the collection methods, although the mean levels of sperm quality with the
flushing method were slightly better than that of the mincing method. The flushing method
is simple and free of blood contamination, although the vas deferens was too small to be
perfused in only 1 dog, and our results suggest that the flushing method is preferable to
the mincing method for collecting sperm from the canine cauda epididymis.
