► Artificial Insemination 
Description: Artificial Insemination New information, new instrumentation, and the availability of new skills needed to be incorporated in the article formerly found here, asking “Why AI” and “Why Not AI”. At the present time, trans-cervical insemination is rapidly becoming more widely available. More information is available about the reliability of in-the-office ELISA tests, and more practitioners interested in small animal reproduction are establishing breeder programs. Information about veterinarians offering reproductive services can be obtained from the membership list of the Society For Theriogenology (animal reproduction). Their web site is at http://www.therio.org and you may contact them for member veterinarians in your area. So, once again, let’s examine the subject of artificial insemination. There are many variations of AI to consider. There is dog-to-dog artificial insemination, fresh-extended (chilled) semen insemination, and frozen semen insemination. Techniques of AI include vaginal deposition, surgical implant, and trans-cervical insemination. Studies have been published with convincing evidence that every semen preparation – fresh, fresh-extended or frozen – will produce larger litters if semen is deposited directly into the uterus, especially with trans-cervical technique. That being said, fresh and fresh-extended semen give decent results with vaginal deposition. Trans-cervical inseminations are done by endoscope or the “Norwegian catheter”. The rigid endoscope is more widely used than the Norwegian catheter, and has the considerable advantage of providing the operator and the bitch’s owner with a view of the actual deposition of semen in the uterus by way of a TV monitor. Those skilled in the use of the Norwegian catheter can get excellent results as well. Trans-cervical semen depositions do not require any sedation at all in nearly all cases.
