Gamete intrafallopian transfer (GIFT) and zygote intrafallopian transfer (ZIFT) are two methods to help a woman become pregnant. With GIFT, sperm and eggs are put in a fallopian tube. With ZIFT, the sperm and egg are first combined in a lab. Then a fertilized egg is put into a fallopian tube.
Why GIFT and ZIFT Are Used
GIFT and ZIFT can help cause 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 may be done through the vagina. Or it may be done with a thin, lighted tube (laparoscope).
Hormone Treatment with GIFT or ZIFT
GIFT or ZIFT may be used with hormone treatment. This can improve the chance of a pregnancy. Your doctor can talk with you about the details, success rates, and costs.
