Zygote Intrafallopian Transfer
Also written as: ZIFT — Zygote Intrafallopian Transfer
An assisted reproductive technique where fertilized eggs (zygotes) are transferred to the fallopian tubes rather than the uterus.
Full Definition
Zygote Intrafallopian Transfer (ZIFT) is a specialized ART procedure that combines in vitro fertilization with laparoscopic transfer of zygotes to the fallopian tubes. The procedure involves retrieving eggs, fertilizing them in the laboratory, and then transferring the resulting zygotes (fertilized eggs before first cell division) into the fallopian tubes within 24 hours of fertilization. This technique allows for natural embryonic development and transport through the fallopian tubes to the uterus. ZIFT is typically considered for patients with unexplained infertility or when previous IVF attempts have failed.
Usage
Usage note: Always capitalize as ZIFT when used as acronym; distinguish from GIFT which transfers unfertilized gametes.
