NCT06156722

Brief Summary

In this prospective randomized sibling-oocytes blinded study, investigators examine the combination of two sperm selection methods that logically seem to complete each other, and potentially may improve ICSI outcomes. The methods include the selection of the optimal spermatozoa based on its morphology by IMSI, together with its physiological function of binding to HA by Spermslow (SS). The current study compared a group of ET after sperm selection by IMSI with SS to a group of ET after sperm selection by IMSI-only without SS, and to a mixed ET group where two embryos were transferred, one after IMSI-only and the other one after IMSI with SS.
