Reference indicators for identifying the performance of the assisted reproductive technology laboratory

RI	Calculation	Benchmark value
The proportion of oocytes recovered (stimulated cycles)	Number of oocytes retrieved/number of follicles on day of trigger ×100	80%–95% of follicles measured
The proportion of MII oocytes at ICSI	Number of MII oocytes at ICSI/number of COCs retrieved ×100	75%–90%

MII=Metaphase II, RI=Reference indicators, COC=Cumulus oocyte complex, ICSI=Intracytoplasmic sperm injections
