What should you know about gavi vitrification?

GAVI vitrification refers to rapid freezing used to preserve eggs or embryos for possible future fertility treatment. The method uses carefully prepared solutions and very rapid cooling to limit ice crystal formation. It does not create a pregnancy or guarantee that a stored egg or embryo will later result in a baby.

Before freezing, cells are exposed to cryoprotective solutions under controlled laboratory conditions. They are then cooled quickly and stored in liquid nitrogen. When needed, the laboratory warms the sample and checks its condition before it is used in treatment.

The outcome depends on factors such as the age and health of the egg or embryo, the number stored, sperm factors, the uterus, and laboratory handling. GAVI may refer to a device, kit, or laboratory approach; ask the clinic exactly which part of your care it describes.

Ask the fertility team whether vitrification is being used for eggs, embryos, or another sample, and what happens before and after freezing. Confirm how samples are labelled, monitored, stored, transferred, and warmed. Request the clinic’s plan for consent, future use, and what happens if storage circumstances change.

If you are considering fertility preservation, read about [Egg Freezing](/treatments/fertility-and-assisted-reproduction/egg-freezing/) and [Vitrification](/technology/vitrification/) to place the laboratory step in context. Your clinician can relate those general concepts to your ovarian reserve and treatment plan.

Vitrification itself is a laboratory procedure, so urgent symptoms usually relate to the ovarian stimulation or egg-collection process rather than the freezing step. Seek prompt medical help for severe abdominal pain, rapidly increasing bloating, breathing difficulty, faintness, heavy bleeding, fever, or very little urine after treatment.

Ask what GAVI means at your clinic, whether the plan is egg or embryo vitrification, how samples are tracked, how long they may be stored, and what warming results can be expected in your situation. Also ask about alternatives, costs, consent, and the next treatment stage.
