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 female.
• Low sperm production in a male.
• Unexplained infertility.

• 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 using a surgical procedure called laparoscopy.

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.
