Kada se pogledaju US statistike, uspješnost samog FET-a veća je za ovu dobnu skupinu od svježeg ET (vrlo vjerojatno se jednim dijelom koristi i PGD):
The percentage of embryos transferred that resulted in implantation among women using frozen nondonor embryos was higher compared with the implantation percentage among women using fresh nondonor embryos (see Figure 31) in the following age groups:
• 21% (frozen) vs. 18% (fresh) among women aged 38–40 years
•15% vs. 10% among women aged 41–42 years
•13% vs. 4% among women aged 43–44 years
•11% vs. 2% among women older than age 44
