With the rise of the "she economy," women's career peaks often overlap with the optimal fertility window, and egg freezing shares are frequent on social platforms, yet often accompanied by doubts about the quality of thawed eggs. In pregnancy preparation planning, US-Mexico egg freezing is renowned for its high revival rates, and many people are curious: are thawed eggs equivalent to fresh ones? Through scientific comparison and clinical data, this technology not only preserves fertility but also provides a reliable foundation for subsequent IVF-PGT applications, avoiding genetic risks brought by age decline.

 

The decline in egg quality with age cannot be ignored. Fertility halves after 35, and the chromosomal abnormality rate soars to 80% over 40, with naturally ovulated eggs prone to carrying variations. Egg freezing locks in premium status at a young age; after stimulation and retrieval, vitrification rapid freezing is used, instantly dropping to -196°C, with metabolism nearly halted and genetic material fixed unchanged. During revival, warm culture medium awakens the eggs, with survival rates reaching over 95% and fertilization capacity comparable to fresh eggs. Studies show that frozen egg babies have no significant differences in IQ, physique, and health indicators compared to naturally conceived ones.

 

The process is designed for safety and efficiency. The stimulation phase monitors hormones and ultrasound to avoid overstimulation; retrieval is minimally invasive with quick recovery. Frozen eggs can be stored for 10-15 years, seamlessly connecting to US-Mexico IVF after thawing, combined with PGT screening to exclude abnormal embryos and improve live birth rates. Supplementing antioxidants like coenzyme Q10 before retrieval can further protect eggs and optimize revival performance. For single women, US-Mexico egg freezing is legally inclusive, with no marriage restrictions, providing flexible buffering.

 

Compared to fresh eggs, the advantage of frozen eggs lies in time autonomy. Fresh egg cycles are constrained by menstruation, while frozen eggs allow optimal timing for transfer, reducing stress interference. Clinical cases confirm that thawed egg pregnancy rates are not inferior to fresh, especially for older preparers achieving healthy second children through US-Mexico IVF.
