Q&A
1. How many eggs should I freeze?
According to the research in 2017, the quality of an egg will decrease with age. To safeguard your choice and ability to conceive, it is recommended that:
▪ 35yr: preserve about 8 eggs
▪ 38yr: preserve about 20 eggs
▪ 40yr: preserve about 35 eggs
2. Will egg freezing cause premature menopause?
At birth, there are approximately 1 million eggs inside a woman’s uterus. By the end of puberty, only about 300,000 remain. Of these, only about 400 will be ovulated during a woman’s reproductive lifetime. Biologically, fertility can drop as a woman ages due to the decreasing number and quality of the remaining eggs. Synthetic hormones are used to stimulate the ovaries to produce multiple eggs - rather than the single egg that typically develops per month, therefore, no, it will not cause premature menopause.
3. What’s the difference between fresh vs. frozen donor eggs? What is the egg survival rate after thawing?
Our clinic uses vitrification, thus significantly increasing the egg thaw survival rates to around 90%. There is no significant health difference between fresh and frozen eggs.
4. What is vitrification?
Vitrification is the process of freezing so rapidly that the water molecules don’t have time to form ice crystals, instead instantaneously solidifying into a glass-like structure.
5. What are the risks of egg retrieval?
After inducing ovulation, the primary concern would be IHSS, but there’s a 5% likelihood of it happening. Some women may experience symptoms such as bloating, nausea, vomiting, and dizziness. Most women will heal automatically within a few days, and only a few women will need to stay in the hospital.
