Egg freezing methods in IVF have been a lifeline to women seeking the flexibility to preserve their fertility for the future. Through refined cryopreservation methods, women everywhere are now able to have informed control over their reproductive abilities and plan for a pregnancy when the time is right.
However, it may be beneficial to also understand its success rates and influencing factors for a more comprehensive understanding of the egg freezing process.
Success Rates of Egg Freezing
The success of an egg freezing session largely depends on the quality and quantity of eggs retrieved, as well as their overall viability. Studies suggest:
- Age Matters: Women under 35 have shown higher success rates, in that, over 85% of eggs retrieved showing viability after having survived the preservation process. After 37, we see a considerable decline in egg quality thus reducing chances.
- Quantity and Quality: When more mature, high-quality eggs are retrieved, the likelihood of successful pregnancy increases significantly. On average, 10-15 eggs are recommended per desired child.
- Technique: Vitrification, or rapid freezing method, has dramatically improved outcomes compared to slower, traditional methods of cryogenic freezing.
Factors Influencing Egg Freezing Success
While it has promising potential, egg freezing results can vary greatly per individual. This is because of the various factors impacting the oocyte’s potential for a viable pregnancy :
- Age at Freezing: Younger women have a healthier reserve of eggs, hence better chances of a viable pregnancy.
- Ovarian Reserve: Conditions like polycystic ovary syndrome (PCOS) can result in more eggs, while a diminished ovarian reserve may require multiple cycles.
- Lifestyle Factors: Smoking, stress, and a poor diet can significantly impair egg quality.
- Clinic Expertise: Expert experience and lab protocols can differ from clinic to clinic, dictating success rates case-by-case.
Conclusion
Egg freezing is a powerful option for women seeking to balance personal goals and family planning. Consulting with a fertility expert to assess individual factors and set realistic expectations for your treatment cycles is the best way down the path to parenthood.
