Egg Freezing FAQ

1. Do I need to schedule an AMH test based on my menstrual cycle?

No. AMH (Anti-Müllerian Hormone) levels are not affected by the menstrual cycle, so the test can be done at any time.

2. If my AMH level is high, do I still need egg freezing?

It depends on individual goals. A high AMH level indicates a higher egg quantity, but egg quality still declines with age. If you are not planning pregnancy soon, egg freezing can help preserve better-quality eggs for the future.

3. Will egg freezing accelerate egg loss or cause early menopause?

No. Egg freezing does not speed up egg depletion or lead to early menopause. The process simply retrieves eggs that would otherwise naturally degenerate during the cycle.

4. Are frozen eggs different from fresh eggs? What is the survival rate?

There is minimal difference. With modern vitrification technology, survival rates after thawing are high. At NUWA Fertility Center, the average survival rate reaches 96.3%, higher than the international average of 70–85%. Pregnancy outcomes using frozen eggs are comparable to fresh eggs.

5. What is vitrification?

Vitrification is an ultra-rapid freezing technique that prevents ice crystal formation. Eggs are cooled at extremely high speeds and stored in liquid nitrogen at -196°C, ensuring long-term stability and minimal damage.

6. Are there risks associated with egg retrieval?

After inducing ovulation, the primary concern would be OHSS, 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. Our medical team will closely monitor your treatment to minimize risks.

Some patients also ask whether ovarian torsion can occur during the egg-freezing process.

Ovarian torsion is extremely rare. It typically becomes a concern only when the ovaries temporarily enlarge due to stimulation medications. During this period, high-impact activities—such as vigorous exercise, jumping, or trauma to the abdomen—may place stress on the enlarged ovary, increasing the risk of torsion, which causes sudden, severe abdominal pain.

Although the likelihood is very low, your doctor will advise you to avoid high-intensity workouts and jumping activities during stimulation to reduce risk.

If you experience sudden, persistent, and severe abdominal pain, please seek medical attention immediately.

7. If I have endometriosis or ovarian cysts, should I have surgery first?

It depends on your condition. A fertility specialist will evaluate and recommend whether to proceed with egg freezing or surgery first.

8. Will egg freezing cause weight gain?

No. Hormonal medications may cause temporary bloating or mild weight changes, which usually resolve within 7–10 days after egg retrieval or by the next menstrual cycle.

9. Do I have to use IVF after egg freezing?

Not necessarily. You may still try to conceive naturally in the future. Frozen eggs can be used later if needed, such as for delayed pregnancy or a second child.

10. How long can eggs remain frozen?

According to Taiwan’s Assisted Reproduction Act, Article 21: Eggs may be stored for up to 10 years.

After 10 years, storage may be extended with your written consent.

Unless you request disposal, pass away, or meet other legal conditions, the stored eggs and your right to use them remain valid and protected.

11. Can I freeze eggs and donate eggs in the same cycle?

No. Egg donation requires strict screening and regulatory approval. If you wish to both freeze and donate eggs, the cycles must be done separately. For example:

You cannot freeze and donate in the same menstrual cycle.

You can donate eggs in June and freeze eggs in July, or vice versa.

If you are interested in egg donation, you’re welcome to complete our egg-donor screening form to schedule an initial evaluation.

12. During egg freezing, can I use weight-loss injections or undergo aesthetic treatments?

Weight-loss injections: Generally, they do not conflict with fertility medications, but they may cause nausea or vomiting. Please assess your tolerance before use during the stimulation phase.

Aesthetic/medical beauty treatments: Please consult with your physician so treatments can be scheduled appropriately based on your health status.

13. Can eggs frozen at another hospital be transferred to your clinic? Can they be shipped overseas?

Yes to both. Transferring eggs from another clinic: Eggs can be transferred between licensed medical facilities.

International export: Eggs may be shipped overseas either independently or with assistance from an international reproductive center.

14. How much does egg freezing cost? How do I pay?

The cost of egg freezing generally ranges from NTD 140,000–180,000, depending on your medical condition, your doctor’s recommendations, and medication needs.

Fees typically include:

Egg retrieval procedure
Egg freezing and laboratory fees
Sedation/anesthesia

Payment is processed in stages based on the medications prescribed, tests performed, and procedures completed on the day of your visit.
