Gamete intrafallopian transfer (GIFT) and zygote intrafallopian transfer (ZIFT) are 2 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.
Why GIFT and ZIFT are used
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
Preparation for GIFT or ZIFT
Medication 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.
Hormone treatment with GIFT or ZIFT
GIFT or ZIFT may be used along with hormone treatment. This can improve the chance of a pregnancy. Your doctor can talk with you about the details, success rates, and costs.
