The Use of Frozen Embryos in In Vitro Fertilization (IVF) Treatment: A Comprehensive Analysis

Introduction

In vitro fertilization (IVF) is a revolutionary solution for couples suffering from infertility. In this context, the use of frozen embryos has proven to be a significant advance that has increased the flexibility and success rates of IVF treatments. This article provides a comprehensive overview of the use of frozen embryos in IVF. It discusses the procedure, benefits, potential risks and recent advances, taking into account the current medical literature.

The Process Of Embryo Freezing

Embryo freezing, also known as cryopreservation, involves several careful steps:

  1. Ovarian stimulation and egg retrieval: First, the woman’s ovaries are stimulated with hormone preparations so that they produce several eggs. These eggs are then retrieved through a minor surgical procedure.
  2. Fertilization and embryo development: The retrieved eggs are fertilized with sperm in the laboratory. The fertilized eggs, which are now embryos, are cultivated for a few days until they have reached a stage suitable for freezing, usually the blastocyst stage (day 5-6).
  3. Cryopreservation: The embryos are frozen using a method called vitrification. This involves rapidly cooling the embryos using cryoprotectants to prevent the formation of ice crystals that could damage the cells. Vitrification has significantly improved the survival rate of thawed embryos compared to older, slower freezing methods.
  4. Storage: The frozen embryos are stored in tanks of liquid nitrogen at temperatures of around -196°C. They can be stored for long periods of time, sometimes several years, without losing their viability.
  5. Thawing and transfer: When the patient is ready for embryo transfer, the embryos are carefully thawed and checked for viability. The surviving embryos are then transferred to the uterus where they can implant and develop into a pregnancy.
