Cryogenic preservation of human oocytes and embryos
An overview of current techniques and success rates
The cryogenic preservation of human eggs and embryos has revolutionized the field of assisted reproductive technologies, offering new hope and opportunities to individuals and couples seeking to start a family. The following section introduces the most modern cryopreservation techniques and explains the remarkable success rates achieved in preserving these precious reproductive cells.
1️⃣ Vitrification:
Vitrification has established itself as the gold standard for the cryopreservation of eggs and embryos. This rapid freezing method involves ultra-rapid cooling of the reproductive cells into a glassy state without the formation of ice crystals. Vitrification minimizes cell damage, preserves the viability of the eggs and embryos, and ensures high survival rates upon thawing. The exceptional success rates achieved with vitrification have made it the preferred method in modern reproductive medicine.
2️⃣ Slow freezing:
Although vitrification dominates the field, slow-freezing techniques still have their place under certain circumstances. Slow freezing involves controlled cooling rates that allow for the gradual removal of water from cells while minimizing ice crystal formation. Although slow freezing is slower and less efficient than vitrification, it remains relevant in certain cases, such as when limited resources or specific patient needs require its use. Ongoing research and developments aim to refine slow-freezing protocols and further improve success rates.
👉 Success rates and clinical outcomes: Remarkable advances in cryopreservation techniques have resulted in impressive success rates and positive clinical outcomes. Vitrification has reported survival rates of over 90% for both eggs and embryos. Furthermore, pregnancy rates using cryopreserved eggs and embryos are comparable to those of fresh cycles, offering individuals and couples scheduling flexibility and a better chance of success. The widespread adoption of cryopreservation has revolutionized fertility preservation, donor programs, and family planning, giving people greater security in their reproductive journey.
