In the journey of fertility planning, many intended parents fall into common misconceptions, especially at an advanced age. We once met a 43-year-old female client who froze her eggs in the U.S. and is now preparing for IVF. However, there were a series of issues throughout her process. Her experience not only reflects the limited understanding of assisted reproductive technology but also highlights the importance of guidance from professional institutions.

 

Common Misconceptions in Fertility Planning for Advanced-Age Women

 

1. Why is egg freezing not recommended for women over 40?

   Many people believe that as long as eggs are frozen, fertility can be preserved for the future. However, for women over 40, especially at 43, egg freezing holds little significance. This is because even if eggs are frozen, they may not produce healthy embryos after thawing. In ovarian stimulation cycles for older women, only a portion of retrieved eggs are mature, and the chance of developing into blastocysts is already low. For example, the probability of a 43-year-old woman forming blastocysts is only about 30% to 40%.

 

2. Why is transferring embryos on Day 3 a mistake?

   In assisted reproduction, the elimination rate of embryos is very high, especially in cycles for older women. The abnormal rate of blastocysts in 43-year-old women may be as high as 90%, and for women at 45, it can reach 99%. Therefore, cultivating embryos to the blastocyst stage (Day 5) and conducting PGD/PGS testing is a crucial step in selecting normal embryos. Directly transferring embryos on Day 3 not only results in low success rates but also wastes significant money and time.

 

How to Plan Fertility Correctly?

 

Faced with these challenges, how should women over 40 plan their fertility journey?

 

1. Prioritize embryo culture

   As mentioned above, for women over 40, directly culturing embryos and trying to reach the blastocyst stage is a wiser choice. Through PGT testing, selecting normal embryos is the key to ensuring IVF success. If, after culture and testing, there are no usable normal embryos, it is better to consider alternatives such as egg donation sooner, rather than relying on risky and low-success egg freezing.

 

2. Choose a professional medical team

   A responsible medical team is not just about executing your instructions, but providing professional advice based on your individual condition and medical logic. They will carefully explain the pros and cons of every process, helping you understand which choices are meaningful and which ones may cause regret. Choosing a clinic that offers transparent and professional consultation is the first step toward success. IVF USA understands your expectations and concerns.
