We’re proud to share our TCI success data from 2025, representing over 250 transcervical inseminations performed throughout the year here at Sirius. While many clinics talk about experience, very few publish their actual annual outcomes. We believe our clients deserve to see real numbers backed by real cases. For us, transparency matters, and so do results.

We did not think we could do much better, but somehow our success rates from last year are even higher than the year before! These numbers reflect hundreds of procedures, meticulous progesterone timing, and a team that is deeply committed to reproductive excellence.
We are incredibly grateful to the breeders and veterinarians who trust us with their programs year after year. Your success is our success, and nothing makes us happier than seeing those puppy photos roll in with the pupdates we receive. 🐶💕
