Embryo with more than 16 blastomeres formed due to in-vitro fertilization is transferred into:

INTRA UTERINE TRANSFER (IUT): In this technique, after In-vitro fertilization the zygote is allowed to develop in to embryo (more than 8 blastomeres). The embryo is transformed directly into the uterus for implantation and further development. Embryos formed by In-vivo fertilization could be used for such transfer to assest those females who fail to conceive.
