A Senior Embryologist from our team is gearing up to share exciting research at the upcoming Pacific Coast Reproductive Society’s Annual Meeting this March! The paper, titled “Timing of Blastocyst Hatching after Vitrification and Warming: Impact on Clinical Pregnancy Rate,” has been selected for oral presentation – an impressive feat given that it was one of only eight chosen from over 100 submissions!
What’s This Study All About?
During ovum development, the zona pellucida (ZP) forms a protective layer around the egg. Previous studies hinted that freezing methods like vitrification might change this membrane’s properties, potentially requiring its removal before transferring frozen embryos. The lead researcher, Dr. Emily Johnson, explained, “We wanted to understand how the ZP responds to blastocyst expansion after warming to help predict implantation success.”
Key Findings
The team found that the ZP’s elasticity decreases significantly after vitrification. They tracked blastocyst changes right after warming and at one and two-hour intervals. Interestingly, embryos with a 20% volume increase in the first hour or 50% in two hours had a much higher clinical pregnancy rate. And guess what? Creating a larger hole in the ZP allowed embryos to hatch fully within just four hours!
This research suggests that some frozen embryos may do better if the ZP is removed post-warming, especially since some embryos got stuck inside despite looking like they were re-expanding properly.

Conclusion
In summary, our Senior Embryologist’s work is set to make waves in the fertility community, emphasizing how understanding the timing of blastocyst hatching can significantly influence clinical outcomes.
