The TCI Standard (Goodbye to Surgical AI)
As of January 1, 2026, many international veterinary associations (such as Greyhounds Australasia) have officially banned Surgical Artificial Insemination. In its place, Transcervical Insemination (TCI) has become the mandatory standard for using frozen semen in dogs.
Non-Invasive Procedure: TCI uses a specialized endoscope (a tiny camera) to visualize the cervix and guide a catheter directly into the uterus.
No Anesthesia: Unlike the old surgical method, TCI is performed while the animal is awake and standing. This removes the risks associated with general anesthesia and eliminates post-operative pain or scarring.
High Success Rates: In 2026, studies show that TCI achieves pregnancy rates of 80–90% with fresh semen and 50–70% with frozen semen, making it just as effective as surgery but much safer.
