The transfer of embryos to the fallopian tubes for the purpose of achieving a pregnancy. Embryos may be transferred at the fertilized oocyte (zygote) stage in a ZIFT (zygote intrafallopian transfer) procedure, or 24 hours later at the 2- to 6-cell stage in a TET procedure. (details)
An ART technique whereby the embryo, grown in the laboratory, is placed laparoscopically into the fallopian tube. This procedure is often used for women who have had prior uterine surgery or who have abnormally shaped uteri because they were exposed to DES in utero. These conditions would make transcervical embryo transfer difficult or impossible.
The placement of an embryo inside the fallopian tube after in vitro fertilization. The process is meant to mimic the natural process of a fertilized embryo traveling down the tube and implanting in the uterus.
