Blastocyst Rates and Kinetics of Sperm Processing After Conventional vs. Piezo-driven ICSI

Equine intracytoplasmic sperm injection (ICSI) is conducted using two main techniques, conventional (Conv) and Piezo-driven (Piezo). Piezo ICSI has been associated with repeatable high (> 25%) equine blastocyst rates per injected oocyte in several laboratories, whereas Conv has been associated with variable and, in general, lower blastocyst rates. Little information is available on direct comparison of the two methods. Because Piezo ICSI entails added equipment expense, requirement for expertise, and typically the use of mercury, use of Conv ICSI would simplify application of ICSI as an equine assisted reproductive technique.
