5 Critical Questions About How to Prepare for IVF in Thailand

1. Why Could the Doctor Retrieve No Eggs Even When Follicles Grow?

A follicle is merely a fluid-filled ovarian sac, while the egg, or oocyte, is the reproductive cell inside it. When ultrasounds show multiple growing follicles, yet no eggs are collected on retrieval day, this condition is called Empty Follicle Syndrome (EFS).

This usually happens when oocytes get damaged at an early developmental stage, yet the follicles keep growing under hormonal stimulation. Women with diminished ovarian reserve may develop empty follicles that lack both granulosa cells and viable oocytes.

Other key causes include:

(1) Abnormal endocrine environment: The follicular fluid lacks bioactive HCG, preventing the cumulus‑oocyte complex from detaching from the follicle wall.

(2) Medication timing or dosage: Some patients require a longer interval or higher dose of HCG trigger to release the egg.

(3) Inherent ovarian response: In rare cases, repeated EFS occurs despite optimal stimulation protocols.

According to peer-reviewed literature, the reported incidence of EFS in IVF cycles varies widely depending on the diagnostic criteria applied and the study population examined. Broader estimates in the literature place the overall EFS occurrence rate between 0.6% and 7%. It is noted that  EFS is not equivalent to ovarian failure and is often a correctable pharmacological issue.

Normally, CEF specialists lower EFS risk by adjusting trigger plans, such as dual trigger and GnRH agonist protocols, and monitoring follicular fluid biomarkers closely.

2. What Should I Do If Adhesions Are Found in the Uterine Cavity?

Uterine adhesions, also referred to as Asherman’s syndrome, develop when damage to the endometrial lining causes the inner uterine walls to fuse. This condition is an important thing to consider before IVF, as it directly impacts embryo implantation.

While uterine adhesions do not affect ovarian stimulation or egg retrieval, they require proper treatment before embryo transfer, with management tailored to the severity of the adhesions.

The standard clinical pathway involves completing ovarian stimulation and egg retrieval to create embryos, followed by vitrifying all viable embryos. Hysteroscopic surgery is then carried out to remove adhesions alongside endometrial rehabilitation, and frozen embryo transfer is arranged only after the uterine cavity has fully returned to normal.

Uterine adhesions most commonly stem from prior uterine procedures such as miscarriage or postpartum D&C, pregnancy termination, or uterine septum correction, as well as intrauterine infections, including endometritis and postpartum infection.

At CEF Bangkok, we arrange routine hysteroscopy ahead of frozen embryo transfer to confirm optimal uterine conditions for successful implantation.

3. What Are the Requirements for Uterine Size and Endometrium Thickness?

Uterine size varies among women, but a normal non-pregnant uterus measures approximately:  4-5 cm wide, 7-8 cm long, and the thickness from front to back is 2-3 cm.

Most anatomical variations (such as a slightly retroverted or small uterus) do not prevent successful IVF. Only major congenital anomalies (e.g., large septum or unicornuate uterus) may require surgical correction.

Endometrial thickness is far more critical. 8-10 mm is the ideal range for embryo transfer. Within this range, uterine receptivity is optimal.

Note: Endometrial pattern (triple-line appearance) and volume are equally important. Doctors use 3D ultrasound to assess both thickness and morphology.

4. How Can I Improve Egg and Sperm Quality Before IVF?

Egg and sperm quality directly influence fertilisation rates, embryo development, and pregnancy outcomes. While age is the single biggest factor for women, both partners can take proactive steps.

For Women (Egg Quality):

Remember: women are born with all the eggs they will ever have. You cannot create new eggs, but you can improve the health of the final cohort that grows during each cycle.

For Men (Sperm Quality):

Sperm are produced continuously, so improvements can be seen within 2-3 months.

It is recommended that both partners start optimising 3 months before egg retrieval for maximum effect.

5. Does IVF Treatment Harm Ovarian Reserve or Function?

IVF does not speed up ovarian ageing nor deplete a woman’s natural egg reserve. In a natural menstrual cycle, multiple follicles start developing in the early stage, yet only one grows to dominance and ovulates naturally; the remaining 10 to 20 follicles would normally undergo atresia and die off on their own.

IVF ovarian stimulation with FSH and LH medications merely rescues these follicles that are already destined to degenerate, enabling them to mature and yield viable eggs instead of being wasted.

Following egg retrieval, the ovaries revert to their normal baseline within one to two menstrual cycles, and repeated IVF stimulation does not lower key ovarian reserve markers.

At CEF Bangkok, we adopt personalised protocols to further safeguard ovarian function:

1. Low-dose mild stimulation: Lower FSH doses plus medicine to protect ovarian response in women with reduced reserve.

2. Natural cycle IVF: Retrieve the single naturally selected follicle for very poor responders.

3. Luteal-phase stimulation: A novel protocol for safe egg retrieval without suppressing the next cycle.

Preparing for Thailand? Actionable Tips and Key Things to Consider Before IVF

Traveling abroad for IVF adds extra planning. Here are the most important things to consider before IVF in Thailand, from logistics to health.

(1) Bring Translated Medical Records: Thai clinics need recent results: AMH, AFC, day‑3 hormones, semen analysis, and any hysteroscopy images. Have everything translated into English. Carry physical or digital copies yourself.

(2) Estimate Your Stay: Fresh transfer cycle needs 12-15 days; Freeze-all (retrieval only) needs 8-10 days; Frozen embryo transfer (FET) needs 7-9 days. Always add 2-3 buffer days for unexpected delays.

(3) Budget for Hidden Costs: Beyond medical fees, include flights, accommodation, food, transport, and medications. Total out-of-pocket for a complete cycle in Thailand is typically included in the package, depending on add-ons like PGT-A.

(4) Language & Communication: All CEF doctors and coordinators speak fluent English. Translation services for other languages (Chinese, Japanese, Korean) are available upon request. 

(5) Prepare Emotionally and Physically: Join online IVF support groups. Watch injection tutorials beforehand. Consider scheduling a counselling session before travel.

(6) Final Pre-Flight Checklist: Medical reports (English) packed, Medications with clinic letter in hand luggage, Clinic’s 24‑hour emergency contact saved, Passport valid for at least 6 months.

These tips apply regardless of which clinic you choose. Being prepared reduces stress, and a calm body and mind always benefit fertility treatment.

FAQs

Can I start IVF if I have mild intrauterine adhesions?

Yes. Mild cases can be treated with medication during the cycle. Moderate or severe adhesions require hysteroscopic surgery before embryo transfer, but egg retrieval can proceed first.

What is the minimum sperm count needed for IVF with ICSI?

With ICSI (intracytoplasmic sperm injection), even a single viable sperm is sufficient. Men with very low counts or azoospermia may require surgical sperm retrieval (TESA/micro-TESE).

Can I travel immediately after egg retrieval?

We recommend staying in Bangkok for at least 1-2 days after retrieval to monitor for any signs of ovarian hyperstimulation syndrome (OHSS). Most patients feel well enough to fly within 48 hours.
