Most of these studies concluded that OPU-DN time did not influence ICSI outcomes, but some suggested that oocytes should be incubated for a short time before DN to improve oocyte maturity and enhance ICSI outcomes.

Oocytes should be pre-incubated for a short duration (preferably 4 h) before DN according to the ART laboratory schedule. More
