The zygote or early embryos (with up to 8 blastomeres) could then be transferred into the fallopian tube (ZIFF-zygote intrafallopian transfer) and embryos with more than 8 blastomeres, into the uterus (IUT intra uterine transfer), to complete its further development.

2. State the importance of this program.
Answer:
