In the assisted reproductive technology where gametes have been fertilized in vitro, which of the following is practicable for embryo transplantation in fallopian tube?
Only embryo (up to 8 blastomeres if zygote is not transplanted)
Only zygote is transplanted, not embryo
Either embryo or zygote with up to 8 blastomere phase transplanted
Morulla with 8-24 celled stage is transplanted in fallopian tube
According to the NCERT text, in the test tube baby programme involving in vitro fertilisation (IVF), the zygote or early embryos (with up to 8 blastomeres) could be transferred into the fallopian tube. This specific technique is known as ZIFT (Zygote Intra Fallopian Transfer). Embryos with more than 8 blastomeres are transferred directly into the uterus (IUT).
