Breeders generally do not do their own ICSI work as the OVU procedure requires the skills and expertise of an experienced reproductive veterinarian. The quote that was mentioned in the article about the Swedish registry was taken from an April 2023 Eurodressage article (April 2023), where that same vet (Dr. Erin Newkirk) provided more details about the difficulty and cost of ICSI - and success rate.
While most breeders think of ICSI as the method to use when a stallion has low-fertility, they seem to ignore that also the mare comes in play and has to undergo a very unpleasant procedure known as OPU (Ovum Pick-Up) or TVA (Transvaginal Aspiration). “You harvest the unfertilised egg. Lots of drugs go into your horse, sedation, NSAIDs, an epidural. It’s a big procedure and very invasive as the ovary is manually retracted. Mares get uncomfortable,” Erin said matter-of-factly. “ICSI is a very specialised technique which is often done for stallions who are dead or have poor sperm quality. It’s micro-manipulation of the oocytes with the microscope.”
The ICSI procedure costs around $8,000 - 12,000 USD in the U.S.A., not counting the stud fee, but the success rate is small. Out of 14 follicles there will be 7 oocytes of which around 5 will mature and can be injected. It often leads to only 1 embryo and sometimes takes between 1 to 3 tries before you have a foal. “There is also more chance for infection in your mare, but the mare’s ovary heals well,” Erin added.
So when the success rate using a highly skilled veterinarian is already so low, why would anyone in their right mind be willing to reduce those odds even further by having someone less trained, less skilled, etc., do the procedure? Sure you might save some money by not having to pay a veterinarian but you may also do irreparable harm to your mare that ends her breeding career or even puts her life in danger.
And again - why would someone subject a mare they love to that kind of invasive procedure, when there are so many other stallions out there? There is also a school of thought that using semen from deceased stallions or much older stallions (say in their 20’s) is moving breeding backwards instead of forwards - and breeding should be about looking to the future. But that maybe is a whole 'nuther discussion…
