Injection location:# Injections are made with a celoscope, laparoscope, or peritoneoscope under general anesthesia.
# Two to three collected eggs are mixed with sperm and injected into one or both fallopian tubes.
# Fertilization location:
# Fertilization takes place in the fallopian tubes, where it would naturally occur.
Applicable Subjects:
# One of the woman's fallopian tubes is blocked.
# The fallopian tubes are open but ovulation is disrupted.
# The woman's egg does not implant well due to an adhesion.
# The man's sperm has trouble reaching the fallopian tubes because of male sterility or endocervical mucous.
Advantages:
# Compared with external fertilization or zygote intrafallopian transfer, this method is more natural because fertilization occurs in the fallopian tubes. Disadvantages:
# Because fertilization is not confirmed at this point, the rate of pregnancy may be low.
ZIFT:Zygote Intrafallopian Transfer
# Same administration techniques as GIFT apply, and this procedure is appropriate for the same subjects who are eligible to undergo GIFT.
# Differs from GIFT, in that after fertilizing the egg with sperm externally, only the confirmed zygotes (fertilized eggs) are transferred to the fallopian tubes.
# Success rates are high when compared to results for test tube babies and GIFT.
GIFT: Gamete Intrafallopian Transfer
Eggs and sperm are collected through such means as external fertilization.
