An important date for Equine Embryo transfer professionals, if interested in attending!

We’re excited to announce that the 11th International Symposium on Equine Embryo Transfer and Technology ( ) and Equine Reproduction Practitioners’ Day will be held in 2026 will be held in 2026! 🐴🎉

📆 August 20–22, 2026 (scientific)
📆 August 23, 2026 (Equine Reproduction Practitioners’ Day)
📍 Lexington, Kentucky

Supported by the ISER Society, ISEET is a premier global conference dedicated to advancing the science and practice of equine reproduction, with a strong emphasis on embryo transfer and assisted reproductive technologies. Learn more about ISEET ➡️ https://bit.ly/47BC8KW

The Equine Reproduction Practitioners’ Day on August 23 will provide lectures taking reproductive management and assisted reproductive technologies for horses from research to reality in daily practice.

Stay tuned for more information on the call for abstracts (opening soon) and the Equine Reproduction Practitioners’ Day!

Professor Tischner pioneered many aspects in the field, and was especially noted for his work in embryo transfer - in particular the production of the first foals using transported embryos.

He will be missed by friends, family and the industry which he loved so much.

Z ogromnym smutkiem przyjęliśmy wiadomość, że 16 października 2025 r. zmarł w wieku 89 lat prof. Marian Tischner - brat ks. Józefa Tischnera i przyjaciel naszego Instytutu.
Łukaszowi, Markowi, Kazimierzowi i całej rodzinie Tischnerów składamy wyrazy głębokiego żalu i współczucia.

Colorado State University Equine Reproduction Laboratory's Professor Pat McCue will be retiring at the end of the year. Dr. McCue has been a veterinarian for almost 40 years, and has been a "household" name in the industry for much of that time, producing practical and useful research and educating several generations of budding veterinarians. Although retiring from practice and Academia, Dr. McCue will still remain involved with equine reproduction as the current chair of the International Society for Equine Reproduction Thank you Dr. McCue from the industry, and we wish you an enjoyable retirement!

Following on from our previous article about processing equine semen, we've dived a little deeper into the subject. Especially when first starting out, many are unable to afford a mechanical counting device, but still have the need to determine s***m concentration in the ej*****te (one cannot reliably produce a quality insemination dose without knowing the s***m concentration!) The answer to the conundrum is the hemocytometer, which - although tedious - can be used to determine that information with accuracy. There are however "tricks" to doing it easily and successfully, and we explain the process and add a few of those tricks to the mix.

It's coming down to the wire! Flights have been booked for our speaker who is going to present, and there are only a few places left! If you are interested in increasing your knowledge of stallion management for breeding and fertility, consider attending this Symposium, which has some outstanding speakers!

Shakespeare may not have put it quite like this, but it's an interesting question none the less!! ISER XIII answered it!!

💥ISER XIII Flashback Monday! 🇧🇷🐎🧪

Seminal plasma is thought to support s***m function, but does it help when added back after freezing epididymal s***m? A team of Argentinian researchers incubated frozen-thawed epididymal s***m (n=40) with 0%, 10%, 50%, or 100% seminal plasma. While motility dropped with higher concentrations, s***m straightness, linearity, and beat-cross frequency improved slightly. There was no effect on viability, membrane function, acrosome status, or morphology. Overall, the study found no clear benefit to post-thaw supplementation, suggesting seminal plasma’s main role may be within the female reproductive tract rather than in vitro.

This research, titled ‘Effect of post-thaw addition of seminal plasma to cryopreserved epididymal equine s***matozoa’, was presented by Gustavo E.A. Olivieri et al. at the Brazilian ISER meeting in 2023.
