- Egg freezing uses the same hormone injections and egg collection as IVF; the eggs are then frozen unfertilised, usually by vitrification.
- Age at freezing matters most. ASRM says it tends to work best in the 20s to early 30s, and estimates each frozen egg has roughly a 2–12 per cent chance of leading to a baby.
- Published Thai prices for one freezing cycle range from about 100,000 baht (a starting price) to an estimated 264,500 baht, and storage is charged per egg, per vial or per sample.
- Thailand's assisted reproduction law was written for married couples. Some clinics state they freeze eggs for single women; using the eggs later is a separate question.
- Ask for the storage agreement, the yearly fee and the rules for moving eggs abroad in writing before you start.

How egg freezing works
Egg freezing follows the first half of an IVF cycle. After tests of ovarian reserve, such as an AMH blood test and an ultrasound count of small follicles, you give yourself daily hormone injections for around ten to twelve days so that several eggs mature at once. Scans and blood tests track the follicles, a trigger injection completes maturation, and the eggs are collected about a day and a half later under sedation, using a fine needle guided by ultrasound.
In the laboratory, the mature eggs are treated with a protective solution and frozen. Most clinics now use vitrification, a very rapid freezing method; the UK regulator, the HFEA, says it is more successful than the older slow-cooling technique. The eggs are then stored in liquid nitrogen until you decide to use them, at which point they are thawed, fertilised by ICSI and any resulting embryo is transferred to the womb. Superior A.R.T. describes the active phase as taking two to three weeks.
Who freezes eggs, and why age matters
People freeze eggs for medical reasons, for example before chemotherapy, radiotherapy or ovarian surgery, and for personal reasons, such as not having a partner or not being ready for a child. ESHRE's guideline on female fertility preservation covers both. Thai clinics present egg freezing in similar terms: Bumrungrad, for example, lists women not yet ready for parenthood and patients facing cancer treatment or ovarian surgery.
The age at which eggs are frozen has the largest effect on how useful they are later. The American Society for Reproductive Medicine says egg freezing tends to work best for people in their 20s to early 30s and is most likely to succeed when eggs are frozen before 38. Superior A.R.T. says there is no strict legal age limit in Thailand but suggests 28 to 35 as the practical window. ASRM also warns that frozen eggs can give a false sense of security if they lead someone to delay trying for a pregnancy.
How many eggs, and realistic expectations
The number of eggs collected varies a great deal. The HFEA says most patients under 38 have around 7 to 14 eggs collected in one cycle, and that collection may not be possible for people with a low ovarian reserve. Not every egg collected is mature enough to freeze, not every frozen egg survives thawing, and not every egg that survives will fertilise and develop into a healthy embryo.
ASRM estimates that each frozen egg has roughly a 2 to 12 per cent chance of leading to a baby, falling with age at freezing. In practice this means some people choose more than one freezing cycle to store more eggs. How many eggs to aim for depends on your age and test results, so ask a fertility specialist to explain their recommendation rather than relying on a general figure. The HFEA describes egg freezing as increasingly successful but not a guarantee of having a baby.
What it costs in Thailand
The three clinics in the table above publish prices for a freezing cycle, but each draws the line in a different place. Superior A.R.T.'s promotional package includes three years of storage. Bangkok Hospital publishes its package in two parts, stimulation then collection and freezing, adding up to an estimated 264,500 baht for patients travelling in for treatment, with storage billed separately. Beyond IVF publishes starting prices, and its two pages describe the cost in different ways.
Storage is where totals diverge over time. A per-egg fee grows with the number of eggs stored: at 2,000 baht per egg per year, ten eggs would cost 20,000 baht a year. A per-vial fee depends on how many eggs the laboratory puts in each vial, so ask how many vials your eggs are likely to need. Superior A.R.T. charges per sample and adds a one-off freezing fee outside its package. Always ask what storage will cost after any included period ends.
Remember the third part of the cost. When you use the eggs, thawing, ICSI, embryo culture and transfer are a separate treatment cycle, and many egg-freezing packages do not price it. Several other Bangkok clinics offer egg freezing but publish no prices online, so ask them for a written quote to compare.
Who can freeze eggs under current Thai rules
Assisted reproduction in Thailand is governed by the Protection of Children Born from Assisted Reproductive Technologies Act B.E. 2558 (2015), which was written around legally married couples. Clinics take different positions on egg freezing for people who are not married. SAFE Fertility Group's international page says single women can freeze eggs for social reasons without a marital-status restriction. Bumrungrad's egg-freezing page says frozen eggs are later fertilised with sperm from the patient's legal spouse.
Freezing eggs and using them are two separate steps. Even where a clinic will freeze eggs for a single woman, creating embryos from them in Thailand later may require you to meet the eligibility rules in force at that time. A revised bill was put out for public consultation in July 2026; as reported, it would extend access to married same-sex couples and allow export of eggs, sperm and embryos with committee approval. It had not been enacted at the time of writing. Ask each clinic, in writing, whether you can freeze eggs there and on what conditions you could use them in Thailand or abroad.
Storage terms and moving eggs later
Storage rules differ by country. In the UK, eggs can be stored for up to 55 years with consent renewed every 10 years, and eggs can be removed from storage if consent lapses or the clinic cannot contact you. Do not assume the same terms apply in Thailand. Bumrungrad says frozen eggs can in theory be kept indefinitely but advises using them within 10 years; SAFE says they can be stored indefinitely. Ask for the clinic's written storage agreement and read what happens if you miss a payment or change your address.
If you live outside Thailand, consider how you would use the eggs. You could return to the same clinic for treatment, or try to move the eggs to a clinic at home. Export of eggs from Thailand is regulated, and the 2026 draft bill proposes committee approval for it. Ask what is required today, who arranges shipping in specialist containers, and whether a clinic in your country can legally receive them. The HFEA also notes that a home-country regulator cannot help if something goes wrong with treatment abroad.
Planning a trip to freeze eggs
If you are travelling, ask whether the initial tests and the first monitoring scans can be done at home and the results sent ahead. You will need to be near the clinic for the later scans, the trigger injection and egg collection, and should allow a day or two to recover before flying. Ask the clinic how many days it expects you to stay, and what happens if your response to the medication means collection is earlier or later than planned.
Keep copies of everything: test results, the number of eggs collected and frozen, the freezing method, the vial labels and the storage contract. These records matter if you later move the eggs or are treated elsewhere.
Questions to ask before you freeze
- Can I freeze eggs here given my marital status, and could I use them later in Thailand?
- Based on my age and tests, how many eggs might you collect, and how many would you suggest storing?
- Do you freeze by vitrification, and what proportion of your patients' eggs survive thawing?
- What exactly does the package include, and what is billed separately?
- How many years of storage are included, and how is storage charged after that: per egg, per vial or per sample?
- What happens to my eggs if you cannot contact me or I stop paying?
- What would thawing, ICSI and embryo transfer cost when I use the eggs?
- What is required to move my eggs to another country, and who arranges it?
Frequently asked questions
How much does egg freezing cost in Thailand?
Among the official clinic pages we checked, published prices for one cycle ranged from a starting price of 100,000 baht at Beyond IVF to an estimated 264,500 baht at Bangkok Hospital for fly-in patients, with Superior A.R.T.'s promotional package at 185,000 baht including three years' storage. Storage and later use cost extra.
Can single women freeze eggs in Thailand?
Some clinics say so: SAFE Fertility Group states that single women can freeze eggs for social reasons. Others refer to using eggs with a legal spouse's sperm. Using the eggs later is subject to the eligibility rules then in force, so ask each clinic in writing.
How long does the process take?
About two to three weeks from the first injection to egg collection, plus any tests beforehand. Some people need more than one cycle.
What is the best age to freeze eggs?
ASRM says egg freezing tends to work best in the 20s to early 30s and is most likely to succeed before 38. Discuss your own timing with a fertility specialist.
Can I take my frozen eggs home?
Export of eggs from Thailand is regulated, and a 2026 draft bill proposes committee approval for it. Ask the clinic what is required today and check that a clinic in your country can receive them before you freeze.
Are frozen eggs a guarantee of a baby later?
No. Each frozen egg has a modest chance of leading to a baby, and that chance falls with age at freezing.
