Knowing the parts of the female reproductive system is key when you are discussing and becoming familiar with different Artificial Insemination techniques and procedures. I'm no expert on canine A.I., but I am an Agriscience Instructor and know a little about A.I. in farm animals.
-----------------------------------------------------------------------
VAGINA--passage between cervix and vulva--where semen is deposited in natural breeding
CERVIX--the neck of the uterus---seperates the vagina and the uterus
UTERUS--where the puppies will grow during pregnancy
UTERINE HORNS--the two branches of the uterus
OVIDUCT---the tubes that lead from the ovaries to the uterine horns and transport the eggs from the ovaries after ovulation-----fertilization takes place here
OVARIES --(2)--produces eggs--the inner most part of the female repro tract
------------------------------------------------------------------------
google canine female reproductive tract and you can find pictures that will give you a good idea of what is going on inside your female
-------------------------------------------------------------------------
With any species, there are two things that are going to increase your chances of getting offspring, 1) TIMING---inseminating the female as close as possible to the time when she OVULATES (when the eggs are release into the oviduct) and 2) LOCATION---placing that semen as close as possible to the place where fertilization actually takes place
---------------------------------------------------------------------------
I got into a discussion with a guy recently who argued with me that you could get a female Artificially Inseminated for $30 or $40 dollars. He didn't understand that there were different types of AI. He had his dog collected and stored and thought you could breed using frozen semen for just a few dollars.
---------------------------------------------------------------------------
When you have the male present, and are collecting him, then Artificially putting it into the female OR you are using fresh chilled semen, using an AI rod and breeding them in a similar manner to that used in hogs and cattle is basically an easy procedure and is pretty successful. Using this method, semen is deposited in the Vagina or Cervix. If you want to increase your success, either breed more than once, or use progesterone tests done by a vet to know when the female is ovulating. Think of this method much like natural breeding. If you were breeding your own dogs, how would you insure getting pups? By breeding at least twice. Everyone has their own methods and you will get more than once answer as to how long semen can survive in the reproductive tract of a female. If you use the Progesterone tests, breeding one time is sufficient.
--------------------------------------------------------------------------
When semen is handled outside of a normal, natural breeding, some of the sperm cells will die. When semen is frozen, some of the sperm cells will die. When the semen is thawed back out, more of the sperm cells will die. When you use frozen semen, you are decreasing your chances of getting pups, because the semen you are using has a GREATLY REDUCED concentration of live sperm. Therefore, you use a technique that may cost more, but increases your chances of getting pups. You could thaw frozen semen out and use an AI rod just like with fresh semen, but the chances of getting pups would be very very slim.
--------------------------------------------------------------------------
surgically implanting semen or using a scope (non-surgical) to implant semen is going to GREATLY increase your chances of getting pups. Using this method, the semen is being placed into the uterine horn or oviduct, very very near the place where the sperm and egg will unite. With this type AI, the sperm cells don't have very far to travel and your chances of success are much much greater. If you are using frozen semen from a dog that is long gone, you don't want to take any chances. Go to a vet that has had very good success with this procedure. Using several progesterone tests, keeping your dog at the clinic for a few days, and surgically implanting can cost $700 to $1000. (Price quoted to me by the closest clinic to me that has a very high success rate)
-----------------------------------------------------------------------
There are a lot of things about reproduction that I don't know. Having it explained in terms that most coonhunters can understand helped me to understand it better. If you are interested in knowing more, you can find tons of information by googling canine reproduction.
Hope this helped.
