Ina assisted reproductive technology where gametes have been fertilized invitro, which of the following is practicable for embryo transplantation in fallopian tube?

(a) Only embryo (upto 8 blastomeres if zygote is not transplanted)

(b) Only zygote is transplanted not embryo

(c) Either embryo or zygote with 8 blastomere phase transplanted

(d) Morulla with 8-24 celled stage is transplanted in fallopian tube

 

(a) In vitro fertilization (IVF-fertilization outside the body in almost similar conditions as that in the body) followed by embryo transfer (ET), ova from the wife/donor (female) and sperms from the husband/donor (male) are collected and are induced to form zygote under simulated conditions in the laboratory. The zygote or early embryos (with upto 8 blastomeres) could then be transferred into the fallopian tube (ZIFT - Zygote Intra Fallopian Transfer) and embryos with more than 8 blastomeres, into the uterus (IUT-Intra Uterine Transfer), to complete its further development.
