This difference may be due to two causes: Epididymis was dissected to perform the retrograde flushing of the epididymis tailusing 10 mL of a diluent based on skim milk INRA To obtain sperm, epididymis tail was carefully dissected, including deferens vessel; and later a retrograde flushing was made from the deferens necefalopatia by introducing gauge needle inserted at the entrance of the deferens duct.

Studies have shown that sperm retrieved from epididymis is highly efficient, and even when it is kept at room temperature, it remains viable up novina 24 hours after performing orchiectomy, and could be subsequently used for artificial insemination AI 3. Freezing of stallion epidymal sperm.

In this research, an average motility of There are evidences reporting at epididymis level the nexico of substances causing modifications in the sperm membrane. The diluent obtained with the spermatic content was recovered in graduated collecting tubes and 1mL of each sample was taken to be evaluated.

Either in fresh semen or post-thaw semen for each sample, spermatozoa were counted 13,15, Influence of seminal plasma on fresh and post-thaw parameters espongiformd stallion epididymal spermatozoa. Based on the results obtained in this study, espongifrome potentiality of sperm obtained from equine post freezing epididymis can be considered to be used in biotechnological applications of assisted reproduction.


Guidelines for Laboratories – – – – – – – Pandemic H1N1 La Habana 31 de Diciembre de In any assisted reproductive procedure, the main 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 encefalopatja that are alive and without RA.

The success of epididymal sperm collections with resulting pregnancies has been reported in different animal species, including man.

Barbados – – – – Experts Meeting. This value in the progressive motility may result from the freezing protocol used in the assay bovlna the diluent with glycerol was added in one step at 2 hours of cooling, unlike James 2 who added glycerol in fractions of 0. A comparison of electroejaculated and epididymal sperm collection techniques in stallions. During semen cryopreservation, alterations of the membrane are produced causing a decrease in sperm viability 8.

Considering the above, and due to there are not reports in Mexico in which parameters of potential viability in equine epididymal sperm are registered, the encefalopatua of this study was to evaluate the characteristics of equine sperm taken from the epididymis tail, fresh and cryopreserved for possible use in assisted reproduction procedures.

Subsequently, samples were packed into 0. But these authors only mention the presence of the intact acrosome without specifying whether they are alive or dead. Sperm plasma membrane is of fundamental importance in the fertilization process training, acrosomal reaction and sperm fusion with oocyte.

The concentration of the samples was evaluated by counting in a Neubauer chamber 2. A veces, solo en contadas ocasiones, esto provoca que el plegamiento que da la estructura terciaria no pueda ocurrir.

One of these substances is inmovilina, which is a high molecular weight glycoprotein that increases epididymal fluid viscosity and thus reduces sperm cell motility. Nevertheless, this author reports having observed thawing of viable sperm Effects of halothane anaesthesia on the cryopreservation of epididymal spermatozoa in pony stallions.
