Piezo‐assisted ICSI improves fertilization and blastocyst development rates compared with conventional ICSI in women aged more than 35 years

摘要

PurposePiezo‐assisted intracytoplasmic sperm injection (Piezo‐ICSI) is reported to be an effective method for inseminating fragile oocytes compared with conventional ICSI (c‐ICSI). However, infertile patient groups suitable for Piezo‐ICSI have not been elucidated. This study was conducted to determine age groups suitable for Piezo‐ICSI using sibling egg controls inseminated by a well‐trained embryologist to reduce technical inequalities.
