Every TC I've seen, the semen is deposited through the cervix and at the "door" of the uterus. Never have they breached the uterine entrance to deposit the semen in each horn. I'll have to ask my vet about that. Liz Ah...which could be the reason everyone has had such a wide range of success w/ the procedure. I use the guy who developed the whole thing. Basically, once the catheter has passed through the cervix, with one hand on the abdomen of the bitch (on the outside) the pipette can be felt through her abdominal wall and the bitch's abdomen/belly are manipulated so that some of the sample is put into each horn (right and left). I'm making it sound complicated, but the whole thing takes a minute or two. (Actually, not to be graphic, but when done correctly, since we are talking about very small area, when they get it just right, you can hear a slight sound, like a sound created by a vacuum). Liz, you mentioned your repro vet when doing surgical implants injects the sperm into the uterus while Carolyn's vet makes a small incision (which is the way I understand our vets do it locally, which is why I would do t-c or probably use a different dog in a different situation rather than create 2 incisions in the uterus, JMO of course. While it's true, the incision is small when the uterus is normal size, when the bitch is pregnant, it sure isn't small, and therefore the possible complications w/ scar tissue). What I'm getting out of this is that some vets, when doing a t-c do little more than a normal vaginal AI; all they are doing is depositing the sample on the inside of the cervix. I'm also finding there are different ways of doing surgical implants. Since I have someone that can get the sample to the exact sample place without anesthesia or (possible) incision, I'm staying with what's easiest on the bitch:) Interestingly enough, though I've never done it, you can also use the same type of procedure and do a fiber optic trans-cervical exam. This would be helpful if you were dealing w/ cysts etc. and needed to know the optimal placement of sperm at a later date.
