Gamete intrafallopian transfer (GIFT) and zygote intrafallopian transfer (ZIFT) are two methods used to help a woman become pregnant. With GIFT, sperm and eggs are put in the fallopian tube. With ZIFT, the sperm and egg are first combined in a lab. Then a fertilized egg is put into the fallopian tube.
GIFT and ZIFT can help produce a pregnancy when some health problems are present. These include:
Mild endometriosis and sperm antibodies in a woman
Low sperm production in a man
Medicine is used to stimulate the ovaries. This causes them to make many mature eggs.
The eggs are removed from the ovaries with a thin needle. This is typically done through the vagina.
GIFT or ZIFT may be used along with hormone treatment. This can improve the chance of a pregnancy. Your healthcare provider can talk with you about the details, success rates, and costs.
