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
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).
