A total of 100 embryos were vitrified, 48 with the automatic dehydrated carrier (ADC) technique and 52 with cryotop. The survival rates in ADC and cryotop groups were similar (85.4% versus 92.3%). The loss rates of 10.4% for the ADC group and 1.9% for the cryotop group were not significantly different. The intact rate was significantly lower in the ADC group (26.8% versus 64.6%; P = 0.001). After 48 h of culture, blastocyst formation rates in the ADC and cryotop groups were 14.6% and 25.0%, respectively, which were not significantly different. In conclusion, the practicability of ADC vitrification was demonstrated. The study has some limitations, which necessitates further work. (C) 2014 Reproductive Healthcare Ltd.
