Embryo Cryopreservation

A technology for preserving high-quality embryos to maintain their condition until the appropriate time for embryo transfer into the uterus, providing greater flexibility in pregnancy planning.

About

What is Embryo Cryopreservation?

Embryo cryopreservation is the process of freezing embryos that have been fertilized and cultured in a laboratory to an appropriate stage, such as the blastocyst stage, for long-term storage.
When the patient is ready, the embryos are thawed and transferred into the uterus in a suitable cycle to prepare for pregnancy.

Embryo Cryopreservation

Suitable for couples who have high-quality embryos from IVF or ICSI and wish to preserve them for future use or subsequent treatment cycles.

Process

Embryo Cryopreservation Procedure

Embryo cryopreservation is performed in a standardized laboratory under strictly controlled environmental conditions throughout every step.

  • 1

    Ovarian Stimulation and Egg Retrieval

    The doctor administers medication to stimulate egg production, followed by egg retrieval from the ovaries at the appropriate time.

  • 2

    Sperm Preparation

    Sperm from the male partner is prepared in a specialized container, either from a fresh sample or previously frozen sperm.

  • 3

    Fertilization and Embryo Culture

    Eggs and sperm are fertilized through an assisted reproductive procedure, and the resulting embryos are cultured in a standardized laboratory.

  • 4

    Cryoprotectant Protection

    Cryoprotectant substances are added to prevent ice crystal formation and to preserve embryo integrity during freezing.

  • 5

    Liquid Nitrogen Storage

    Embryos are stored in liquid nitrogen tanks at approximately -196°C for future embryo transfer.

Purpose

What is the purpose of embryo freezing?

Embryo cryopreservation allows high-quality embryos to be preserved for future use without the need to repeat ovarian stimulation and egg retrieval each time.

Preserve surplus high-quality embryos from IVF treatment

Allow embryo transfer in subsequent cycles if pregnancy is not achieved in the first attempt

Reduce the need for repeated ovarian stimulation and egg retrieval

Enable long-term embryo storage

Support flexible family planning based on the most appropriate timing

Benefits

Advantages of Embryo Cryopreservation

Increased flexibility

Helps couples plan embryo transfer at a more suitable and prepared time.

Reduces repeated procedures

If high-quality embryos remain, they can be used in subsequent cycles without the need for another egg retrieval.

Preserves embryo quality

Uses freezing technology that helps reduce ice crystal formation and maintain embryo integrity.

Suitable for family planning

Helps infertility treatment be planned in a more structured and step-by-step manner.

Safety

Does embryo freezing affect future babies?

Embryo cryopreservation is performed by embryologists and specialists in a standardized laboratory using advanced technology. The process is designed to preserve embryo quality and ensure safety throughout the treatment.
