Who could benefit from zygote intrafallopian transfer?

Old treament. Zift, or zygote intrafallopian transfer is an old technology that is no longer in use. It is more invasive than routine ivf because it requires abdominal surgery (laparoscopy) and pregnancy rates are lower.
Not indicated. Zift is rarely done now. Improvements in lab culture techniques have improved implantation and pregnancy rates with ivf, so zift is rarely helpful.

What is zygote intrafallopian transfer?

ZIFT. Zygote intrafallopian transfer (zift) is a surgical, laparoscopic, procedure where a zygote is placed in the female's fallopian tube. The zygote continues to grow and migrates to the uterine cavity where it implants. Read more...
Embryo into tube. Zygote intrafallopian transfer (zift) is placement of an embryo into the fallopian tube, usually under laparoscopic guidance. Zift is now rare, since fertility specialists tend to avoid the risks associated with surgery, and lab culture techniques have improved so that embryos can be grown to advanced stages in the ivf lab.

What is involved in zygote intrafallopian transfer (zift)?

ZIFT. Zygote intrafallopian trasfer (zift) is a laparoscopic surgical procedure where zygotes are placed in the fallopian tube of the female partner. The zygote will continue to grow and eventually migrate to the endometrial cavity to implant. Read more...

Who is not a suitable candidate for zygote intrafallopian transfer?

Older procedure. Zygote intrafallopian transfer (zift) is an older procedure which has been replaced by the current in vitro fertilization and embryo transfer techniques utilized these days. Zift requires normal fallopian tubes. Read more...
ZIFT candidate. Embryos live best in the environment of the tubes which act as natural incubators. For women older than 42, ivf may not offer much advantage over the natural cycle. Some studies had shown that placing embryos (zift) or the sperm and eggs (gift) into the distal tubes could yield higher live birth rates than ivf. For most patients, however, ivf is more cost effective than zift or gift. Read more...
