Who is not a suitable candidate for zygote intrafallopian transfer?

Who is not a suitable candidate for zygote intrafallopian transfer?

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

What was the problem with zift?

What was the problem with zift?

Rarely used any more: Zift is / was more invasive than ivf because it requires laparoscopy to transfer the zygotes into the woman's tube. Compared with modern ivf (in vitro fertilization) zift has lower success rates, has less ability to select the 'best' embryos, and depends on the tubes being fairly functional. These are all reasons why it has been superseded by ivf. ...Read more

Unless there is no way to get an embryo into your cervix and into the uterus (severe scarring, permanent cerclage, etc), normally those would never be used anyway ...Read more
