Zygote Intra-Fallopian Transfer

Unlike GIFT, these procedures allow for laboratory observation of fertilization in vitro. In TET, forty eight hours after retrieval the resulting embryos are surgically transferred into the woman's fallopian tubes. In ZIFT, twenty four hours after retrieval, the resulting zygotes are transferred into the woman's tubes.

TET/ ZIFT can be a treatment of choice for patients with cervical abnormalities, a history of prior difficult cervical embryo transfer and male factor issues.
