An embryo formed by in-vitro fertilization has developed to the 16-blastomere stage. Which of the following correctly identifies the assisted reproductive technique and the specific anatomical site where this embryo should be transferred?

Step-by-step solution

According to NCERT, in Embryo Transfer (ET) techniques, the zygote or early embryos with up to 8 blastomeres are transferred into the fallopian tube (ZIFT - Zygote Intra Fallopian Transfer). Embryos with more than 8 blastomeres are transferred into the uterus (IUT - Intra Uterine Transfer) to complete their further development. Since the embryo in question has 16 blastomeres (which is greater than the 8-cell threshold), the correct technique is IUT and the anatomical site of transfer is the uterus. Selecting ZIFT o
