In the In Vitro Fertilisation (IVF)/Test-Tube Baby programme, an early embryo with **up to 8 blastomeres** is transferred into the:
AFallopian tube (ZIFT)
BOvary
CUterus (IUT)
DVagina
Answer & Solution
Correct answer: A. Fallopian tube (ZIFT)
Rule of thumb: **≤8 blastomeres → fallopian tube** (ZIFT — Zygote Intra Fallopian Transfer). **>8 blastomeres → uterus** (IUT — Intra Uterine Transfer). The fallopian tube provides the natural early environment before uterine implantation.
