(TCI) is a technique that is popular because it can be used with any form of semen (fresh, fresh-chilled, and frozen). It is one of the few options that should be used with frozen or poor-quality semen. It is a good option for large and giant breed dogs and when only one breeding can be performed. This technique can be performed either with palpation or the use of an endoscope to help see the cervix. In this technique, a catheter is used to bypass the cervix and deposit semen directly into the uterus. Sedation is typically not needed, as most bitches will stand for the procedure.
