The Zygote intrafallopian transfer is a way of conception which is similar to that of IVF. The difference comes in the procedure where the eggs are fertilized outside the body. The doctor fertilizes the eggs in a lab and then places them inside the fallopian tubes. These eggs which are fertilized are called zygotes.

Zygotes are eggs which are one-celled embryos and have not begun to multiply yet. This method of conception is ideal for those who have at least one fallopian tube open and other ways of conception have been unsuccessful. ZIFT can help women who have unexplained infertility and ovulation problems.
How Does ZIFT Work?
The steps for ZIFT are similar to those followed for an IVF.
- Ovary Stimulation
The treatment starts with the intake of medicines that a woman is required to take at the beginning of each cycle in order to release mature eggs and to prevent the eggs from releasing too soon.
- Follicle Development
The doctor checks for the developing follicles and takes measurements in an ultrasound. The doctor also check for the blood hormone levels.
- Gathering the Eggs
Once the eggs are ready for retrieval, an ultrasound probe in inserted in the woman to extract 8 to 15 eggs at once.
The doctor then fertilizes the egg with the partner’s sperm in a lab. These are closely monitored and after about a day, the eggs are fertilized into single-celled embryo called a zygote.
The entre process takes about 4 to 6 weeks for one cycle. This test can be done again if the results were unsuccessful in the first try.
