In the real context of continuously delayed childbearing age, more and more families encounter the problem of recurrent miscarriage during the preconception process. Compared with “unable to conceive,” repeatedly losing pregnancies more easily brings sustained psychological pressure and makes every subsequent choice more cautious.

 

Recurrent Miscarriage Is Not Just an Accidental Event

 

In medicine, recurrent miscarriage is usually defined as two or more consecutive natural miscarriages. Most miscarriages occur in early pregnancy and often end before the cause is fully confirmed. This “interruption without answers” is also the reason why many people remain repeatedly confused.

 

Before entering the next round of preconception, clarifying the source of the problem is more important than blind attempts. Miscarriage is not caused by a single factor but by the叠加 of multiple conditions; therefore, evaluation needs to be carried out from three levels: embryo, maternal, and male factors.

 

Embryo Factors Are the Key Starting Point

 

Among many causes, embryonic chromosomal abnormalities account for a high proportion. Even if both husband and wife have normal test results, chromosomal separation abnormalities may still occur during the combination of sperm and egg, resulting in the embryo being unable to develop normally.

 

This is also why, in the US and Mexico IVF pathway, IVF-PGT has gradually become an important option. Through preimplantation genetic screening, chromosomally abnormal embryos can be identified before transfer, reducing the probability of miscarriage from the source. For people who have experienced multiple miscarriages, this step is often more practically meaningful than simply increasing the number of attempts.

 

Maternal Environment Also Affects Outcomes

 

Successful embryo implantation depends not only on its own quality but also on the uterine environment and immune status. If the endometrial conditions are unstable or there are immune abnormalities, even a normal embryo may have difficulty maintaining development.

 

In addition, insufficient luteal function will also affect early pregnancy support. Some people may only show slight changes in the menstrual cycle, but in actual pregnancy it becomes a key variable. Therefore, during the preconception adjustment stage, hormone testing and uterine assessment can help identify these “hidden factors.”

 

Male Factors Should Not Be Ignored

 

In discussions of recurrent miscarriage, male factors are often underestimated. Sperm quality not only affects the fertilization process but also influences subsequent embryo development. If there are issues such as low sperm motility or abnormal morphology, embryo quality may also be affected.

 

In such cases, even when entering a US and Mexico IVF cycle, synchronous assessment of sperm conditions is still required, and the fertilization method should be adjusted according to the results to reduce potential risks.

 

For people who have tried multiple times without success, introducing assisted reproductive technology becomes more targeted. For example, in the US and Mexico IVF process, through personalized ovarian stimulation, embryo screening, and optimization of transfer protocols, uncertainty can be reduced to a certain extent.

Once the data gradually becomes clear, many decisions are no longer so difficult. The IVF USA team established by Dr. Nathan Zhang has been engaged in overseas assisted reproduction consulting services for more than ten years, providing services such as US egg freezing, US IVF, and third-party assisted reproduction for those in need. IVF USA, which has been deeply involved in the overseas assisted reproduction field for nearly 20 years, laid out the Mexican market early based on the diversification and personalization of reproductive needs and became the Chinese agent for Power Fertility Center Mexico POWER Reproductive Center (POWER IVF). At present, Dr. Nathan Zhang’s business has expanded to Mexico IVF and egg freezing beyond the United States, as well as Japan, Thailand IVF and egg freezing, and regions such as Taiwan and Hong Kong.
