Which of the following statements regarding Zygote Intra Fallopian Transfer (ZIFT) and associated reproductive processes are NOT correct? S1: ZIFT stands for Zygote Intra Fallopian Transfer, a method where an early embryo (up to 8 blastomeres) is transferred into the fallopian tube. S2: The reason for transferring early embryos into the fallopian tube during ZIFT is that it mimics the natural site for fertilization and subsequent early embryonic development. S3: If an embryo formed *in vitro* has more than 8 blastomeres, it is always transferred into the fallopian tube to complete its development. S4: ZIFT is exclusively employed for embryos formed through *in vitro* fertilisation, not for embryos conceived *in vivo*. S5: Infertility issues where the female cannot produce ova are typically addressed by ZIFT using donor ova.
