Question

at how many cell stage embryo will transfer in zift​

Answer 1

Explanation:

ZIFT is normally performed in the pronuclear stage, 1 day after egg retrieval. For practical reasons, ZIFT is sometimes deferred by 1 day, and cleavage stage embryos are transferred 2 days after egg retrieval, a procedure previously termed 'embryo intra-Fallopian transfer', or EIFT (Levran et al., 2000).
