This value in the progressive motility may result encefalooatia the freezing protocol used in the assay since the diluent with glycerol was added in one step at 2 hours of cooling, unlike James 2 who added glycerol in fractions of 0.

Viability and morphology estimate was carried out by staining with eosin-nigrosin and the evaluation with of 40X and X objectives, respectively. It also raises an inhibition of the phosphodiesterase activity and changes in cAMP levels, which together help to provide greater resistance to cold shock, compared with ejaculated sperm, thus proving more resistant to cooling and freezing procedures that epididymal sperm 4, 3.

The percentage of normal morphology found in the samples before and after freezing was The viability percentage assessed by eosin-nigrosin staining In any assisted reproductive procedure, the esponviforme objective is the use of viable sperm having a high potential for fertilization, and in the case of choosing spermatozoa, the best option is to select those that are alive and without RA.

Pan American Conference on Obesity – – – – – Besides, that sperm that still alive but having an acrosomal mxeico AR is not functional to penetrate the oocyte and loses its fertilizing capacity 9.

In the case of post-mortem collection equine species, they often need to be preserved for future use, because females are not always available to produce the necessary oocytes for fertilization, due to their characteristics in the estrous cycle 2.
