Intrafallopian gamete transfer is a fertility treatment that involves placing a mixture of eggs and sperm into a woman’s fallopian tube. It is used for women who have difficulty conceiving and have been trying for a year or more. The procedure may not be effective for certain conditions involving the fallopian tubes or uterus. The success rate is around 50%, but may be lower for older women.
Intrafallopian gamete transfer, also called fallopian tube gamete transfer, is a treatment for women who have difficulty conceiving a child. It is used to place a mixture of egg and sperm into a woman’s fallopian tube, which is a tube that carries a woman’s egg to her uterus. If the procedure goes as planned, at least some of the eggs are fertilized in the fallopian tube.
Fertility doctors may recommend intrafallopian gamete transfer for a single woman or a couple who have been trying to conceive a child for a year or more and have been unsuccessful. It can be used to treat women who are infertile for a variety of reasons, but may be ineffective for women with certain conditions involving the fallopian tubes or uterus. Among these conditions are blocked fallopian tubes, significant damage to the tubes, and structural problems of the uterus. Intrafallopian gamete transfer can be used to treat couples dealing with male infertility, but in these cases IVF is considered a more effective option. In vitro fertilization involves inserting already fertilized eggs into a woman’s uterus.
If a woman chooses to have intrafallopian gamete transfer, a fertility specialist gives her drugs to stimulate her ovaries to produce many eggs instead of just one. Once the eggs are mature enough, the doctor removes them from the woman’s body using a procedure called aspiration. Some of the eggs are mixed with approximately 200,000 sperm cells soon after they are removed from the woman’s ovaries. Finally, the fertility doctor injects the sperm and egg mixture into the woman’s body using a type of minor surgery called a laparoscopy and waits to determine whether a pregnancy will develop.
The laparoscopic surgery used to place the sperm and egg mixture into a woman’s fallopian tube is done through very small incisions in the abdomen. This allows the doctor to thread a thin tube with a small camera attached into your body. She then uses another type of thin tube, called a catheter, to inject sperm and eggs into her fallopian tube.
Generally, women who opt for intrafallopian gamete transfer have about a 50% chance of conceiving a child. Often, older women have a less than 50 percent chance of conceiving with the help of this procedure. If an older woman produces a lot of eggs, however, her doctor may put more of them in her fallopian tube than he would if she were younger. This can help make her chances of conceiving equal to a younger woman’s.
