An effective method for improving outcomes in patients with a fertilization defect / 대한생식의학회지

ABSTRACT

The effect of artificial oocyte activation (AOA) with a calcium ionophore on intracytoplasmic morphologically selected sperm injection (IMSI) was examined in patients with histories of repeated failed implantation attempts. Four singleton pregnancies and one twin pregnancy were obtained after embryos transfer (5/14, 35.7%). Therefore, AOA combined with IMSI can be considered an option for cycles with a fertilization defect and recurrent implantation failures.
