Tubal Embryo Stage Transfer (TEST) is a medical procedure used in assisted reproductive technology to transfer embryos into the fallopian tubes. It is a type of embryo transfer that takes place at the stage when the embryo is typically present in the fallopian tubes.
During the TEST procedure, embryos that have been fertilized in a laboratory through in vitro fertilization (IVF) are transferred directly into the fallopian tubes rather than the uterus. This is done by accessing the fallopian tubes through a small incision in the abdomen, guided by ultrasound imaging.
The main objective of Tubal Embryo Stage Transfer is to imitate the natural process of fertilization and early embryo development occurring in the fallopian tubes. By transferring the embryos to the ideal environment, it is believed that their chances of successful implantation and development are improved.
Tubal Embryo Stage Transfer is most commonly performed in women who have experienced tubal factor infertility, where there is a blockage or damage to the fallopian tubes. It is also used in cases where the quality of the eggs or embryos is compromised.
This procedure is generally considered safe, although risks such as infection, bleeding, or injury to the fallopian tubes or nearby organs are possible. The success rate of TEST varies depending on various factors including the woman's age, overall health, and the quality of the embryos being transferred.
Overall, Tubal Embryo Stage Transfer offers an alternative method for embryo transfer, aiming to maximize the chances of successful pregnancy in women facing infertility issues related to the fallopian tubes.
