Egg Freezing & Sperm Freezing
Preserving Your Options for the Future
In modern society, family planning is no longer limited by age or timing.
Through advanced reproductive medical technology, you can create greater flexibility and security for your future plans.
Egg and sperm freezing are not decisions about the present —
they are preparations that give you more choices for the future.
What Is Egg Freezing?
Egg freezing (oocyte cryopreservation) involves ovarian stimulation and egg retrieval, after which mature eggs are vitrified and stored in liquid nitrogen at –196°C. When needed in the future, the eggs can be thawed and fertilized.
🤍 Egg freezing is about preserving peace of mind.
Egg quantity and quality of a woman naturally decline with age.
Through vitrification, eggs retrieved at a younger age which has better quality can be preserved for future use when pregnancy is desired.
Advantages of Egg Freezing
· ✨ Preserves eggs at a potentially better quality
· ✨ Reduces uncertainty related to advanced maternal age
· ✨ Allows planning independent of relationship or marital status
· ✨ Preserves fertility before cancer treatment
This is not an impulsive decision —
it is a gift to your future self.
Who May Consider Egg Freezing?
· Women not planning immediate pregnancy
· Women over 30 who wish to preserve higher-quality eggs
· Individuals preparing for cancer or major medical treatments
· Those working abroad long-term or in long-distance relationships
· Individuals whose fertility may be at risk due to medical factors
What Is Sperm Freezing?
Sperm freezing (sperm cryopreservation) involves analyzing and processing a semen sample, then preserving it at ultra-low temperatures for future use in intrauterine insemination (IUI) or in vitro fertilization (IVF) treatments.
Benefits of Sperm Freezing
· ✔ Preserves healthy sperm quality
· ✔ Safeguards fertility before surgery or medical treatments
· ✔ Provides a backup option for long-term overseas assignments or separated partners
· ✔ Increases flexibility in treatment schedule

A Reassuring Choice for the Future
Egg and sperm freezing do not necessarily mean they will be used in the future. They simply ensure that you still have options when the time comes.
If you would like to understand your current fertility status or determine the most suitable timing for preservation, we welcome you to schedule a professional consultation with our physicians.
Egg Freezing FAQ
Q1: What is the best age to freeze eggs?
Generally, evaluation is recommended before age 30–35.
Egg quality is closely related to age — the younger the eggs at the time of freezing, the higher the potential success rate in the future.
However, individual assessment (such as AMH levels and ovarian reserve testing) is necessary.
Q2: Is egg freezing painful?
Egg retrieval is performed under intravenous sedation and takes approximately 15–20 minutes.
Most women experience only mild bloating afterward and can usually resume normal activities within 1–2 days.
Q3: How many eggs should be frozen?
The recommended number varies by age:
· Under 35: approximately 15–20 eggs
· Age 35–38: more eggs may be recommended
The exact number depends on individual ovarian response and medical evaluation.
Q4: How long can eggs be stored?
When preserved in liquid nitrogen at –196°C, eggs can theoretically be stored long-term.
Current medical research shows stable success rates even after many years of storage.
Q5: Does egg freezing guarantee pregnancy?
Egg freezing is not a guarantee of future pregnancy.
It increases the possibility of success, but outcomes depend on age at freezing, number of eggs preserved, and future treatment conditions.
Q6: How long does the egg freezing process take?
The process begins on day 2–3 of the menstrual cycle, followed by approximately 10–12 days of ovarian stimulation.
The entire cycle is typically completed within two weeks.
Q7: Can single women freeze their eggs?
Under current regulations in Taiwan, single women are allowed to undergo egg freezing.
However, future use must comply with assisted reproduction laws and regulations.
