Artificial Insemination 1
|
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.
