Effect of Oocyte In Vitro Maturation Interval on Subsequent ICSI Embryo Quality and Development

Demand for in vitro equine embryo production by ICSI has increased in clinical reproduction over the last 5 years. However, the efficiency of this technique remains variable with reported blastocyst rates between 10 and 41%. Oocytes recovered by transvaginal follicular aspiration from donor mares are valuable and limited, and they are often collected from immature follicles. These oocytes require further in vitro maturation in order to be competent to be fertilized and reach the blastocyst stage.
