Egg Freezing in Bangkok, Thailand
Egg freezing lets you store your own unfertilized eggs now and decide later when, and with whom, to use them. At Lifespan Birth in Bangkok, Thailand, egg freezing is included in our OPU package: we stimulate your ovaries, collect your eggs under light sedation, and freeze them in our own laboratory for long-term storage.
What Is Egg Freezing?
Egg freezing, known clinically as oocyte cryopreservation, is the collection and freezing of a woman's eggs before they are fertilized, so they can be used later in IVF treatment. The eggs are frozen by vitrification, a rapid freezing method that stops damaging ice crystals from forming inside the egg.
Egg Freezing vs Embryo Freezing
Embryo freezing stores eggs that have already been fertilized with a partner's or donor's sperm. Egg freezing stores your eggs on their own. No sperm is needed and no decision about a partner or donor has to be made today. If you already plan treatment with a partner, your doctor can talk you through embryo freezing too.
Who Should Consider Egg Freezing?
Egg freezing is recommended for:
Women in their 30s who want to delay starting a family
Women with a low or falling ovarian reserve, shown by an AMH blood test or ultrasound scan
Women preparing for chemotherapy, radiotherapy, or ovarian surgery that may affect fertility
International patients who want to freeze their eggs in Thailand and keep their options open
The Egg Freezing Process
Daily hormone injections encourage several eggs to mature in one cycle, rather than the single egg your body releases each month.
Ultrasound scans and blood tests at our Bangkok clinic track your follicles and hormone levels, so your doctor can adjust your medication and time the collection.
After a final trigger injection, your eggs are collected through a thin needle guided by ultrasound. This is done under light sedation, and most patients recover within 24 hours.
Our embryologists assess each egg and vitrify the mature ones in our laboratory.
Your eggs are labeled and stored in liquid nitrogen at around -196°C under continuous monitoring.
Egg freezing follows the first stages of an IVF cycle and stops before fertilization. From the first injection to freezing usually takes two to three weeks.
Most women under 38 have around 7 to 14 eggs collected in one cycle, according to the UK Human Fertilisation and Embryology Authority. Your doctor will estimate your likely number from your AMH result and scan.

How Long Can Frozen Eggs Be Stored?
Vitrified eggs can stay frozen for many years. The American Society for Reproductive Medicine advises that the length of time eggs have been stored does not affect how well they survive or the chance of pregnancy. We offer long-term storage in our Bangkok laboratory for local and international patients.
What Happens When You're Ready to Use Your Eggs?
When you are ready, your eggs are warmed and fertilized with your partner's or a donor's sperm using ICSI, the standard method for frozen eggs. The embryos are cultured for 3 to 5 days before one is transferred to your uterus, and any others can be frozen for later.
Egg Freezing Success Rates and Age
Your age when you freeze your eggs matters more than any other factor. Eggs frozen younger are more likely to survive warming, fertilize, and lead to a pregnancy, and the same ASRM guideline reports noticeably lower pregnancy rates for women who froze at 38 or older. Your eggs keep the quality they had on the day they were frozen, however long they are stored.
Not every egg will fertilize or grow into an embryo, and egg freezing cannot guarantee a future pregnancy. Your doctor will give you an honest estimate at your first consultation, based on your age and test results. For a closer look at the numbers, read our guide: Is egg freezing worth it?
Preparing for Egg Freezing
Before you start, you will need to:
Have an AMH blood test and an ovarian ultrasound scan, which can be done at home before you travel
Tell us about any medications, supplements, or medical conditions
Plan to be in Bangkok for two to three weeks for stimulation, monitoring, and egg collection
Your first consultation can be held by video, so your stimulation plan is agreed before you travel.

FAQs About Egg Freezing
Results are better the younger you freeze, and many women freeze in their early to mid 30s. Freezing after 38 is still possible, but fewer eggs are usually collected and each has a lower chance of leading to a pregnancy.
It depends on your age and ovarian reserve: women who freeze younger usually need fewer eggs for the same chance of a baby. Your doctor will suggest a target after reviewing your results, and some women do more than one cycle to reach it.
Most women have mild bloating, tenderness, or mood changes during stimulation, and some cramping for a day or so after collection. Rarely, the ovaries over-respond and cause ovarian hyperstimulation syndrome (OHSS), which is why your hormone levels and follicles are monitored closely throughout the cycle.
Egg freezing does not stop you trying to conceive naturally. Your frozen eggs stay in storage as a back-up you can use if you need fertility treatment later.
