ICSI (Intracytoplasmic Sperm Injection)
ICSI is a highly advanced procedure, which allows reproductive specialists to isolate one sperm from your partner with which to fertilize one of your eggs. Once fertilization has taken place, the embryo is allowed to develop for a few days and is then implanted into your uterus at the appropriate time of your cycle.
GIFT (Gamete Intrafallopian Transfer)
GIFT is often used as an alternative to the IVF procedure. Eggs and sperm are collected from you and your partner. These are then mixed in tiny plastic cylinders, similar to straws, and the mixture is inserted into your fallopian tubes. Fertilization takes place inside of your fallopian tubes, instead of outside of your body.
ZIFT (Zygote Intrafallopian Transfer)
ZIFT is very similar to GIFT, however, fertilization takes place before the egg is placed inside of your fallopian tubes. A sample of sperm is mixed with your harvested eggs. Once fertilization has taken place (creating a zygote) the fertilized egg is implanted surgically into your fallopian tubes.
Preparing for Assisted Reproductive Technology
Before you can begin ART procedures, your reproductive endocrinologist will likely administer fertility drugs. These fertility drugs will help to induce ovulation, allowing more eggs to be released during your monthly cycles. Common fertility drugs used to induce ovulation include:
- Urofollitropin and Recombinant FSH
Success Rates of Assisted Reproductive Therapy
The success rates of ART procedures vary depending upon your health, fertility issues, and the specific procedure that your choose to undergo. Success rates for popular ART procedure are as follow:
- IVF: Success rates for IVF treatment procedures are generally between 25% and 35% per treatment cycle.
- ICSI: Success rates for ICSI treatment is generally 20% per cycle.
- GIFT: GIFT success rates are typically high, with a 24% live birth rate per cycle.
- ZIFT: ZIFT success rates are slightly higher than those produced by GIFT. ZIFT is associated with a live birth rate of 29%.
