The success rates of in vitro fertilization (IVF) procedures in the United States, particularly when using one’s own frozen eggs, exhibit notable differences based on the age at which the eggs were initially preserved. If you have chosen to freeze your eggs at a younger age and are now considering their utilization, the likelihood of success is generally more promising compared to utilizing your own eggs at an older age. This heightened probability can be attributed to the inherent youth of the frozen eggs, which enhances the potential for successful embryo development.
A study published in the journal Fertility and Sterility in 2017 sheds light on this phenomenon. The research found that the live birth rate for IVF procedures using frozen eggs from women under 35 was an impressive 47%, surpassing the 40% live birth rate observed when fresh eggs from women in the same age group were used. Moreover, the study unveiled a higher implantation rate (the percentage of embryos successfully attaching to the uterus) for frozen eggs, standing at 35%, in contrast to the 30% implantation rate for fresh eggs.
The superior performance of frozen eggs is attributed to various factors, including the avoidance of aging effects, immediate fertilization post-thaw, and minimized risks of egg damage during the freezing and thawing processes.
For individuals contemplating IVF with the use of frozen eggs, seeking guidance from a fertility specialist is crucial. A comprehensive consultation with a specialist allows for the evaluation of specific advantages and disadvantages tailored to your unique situation. By collaborating with a fertility expert, you can make informed decisions that align with the best interests of your fertility journey.
| Age of Woman | Success Rate |
| Under 35 | 40% |
| 35-37 | 35% |
| 38-40 | 30% |
| 41-42 | 25% |
| 43-44 | 20% |
| 45-46 | 15% |
| 47-48 | 10% |
Worldwide IVF success rates vary significantly by country due to differences in medical practices, regulations, healthcare quality, and patient demographics. Here’s an overview based on averages and trends observed in various regions:

Key Factors Affecting Success Rates Globally
Global success rates provide a broad range, but individual outcomes depend greatly on age, health factors, and the specific clinic’s protocols and technology.
Egg donation is a process where a woman (the egg donor) provides one or several eggs (also known as oocytes) for purposes of assisted reproduction, with the eggs being fertilized in the laboratory. Once fertilized, the resulting embryos are transferred to the recipient’s uterus to initiate a pregnancy, or they can be cryopreserved (frozen) for future use.
