Treatment
IVF & ICSI
Controlled fertilisation.
Monitored at every stage.
IVF (In Vitro Fertilisation) is a process where eggs are collected from the ovaries, fertilised with sperm in our laboratory, and cultured into embryos under controlled conditions. ICSI (Intracytoplasmic Sperm Injection) is a refinement — a single sperm is selected and injected directly into the egg, bypassing natural barriers.
Every IVF cycle uses ICSI by default. It gives our embryologists direct control over fertilisation and removes a variable from the process.
Who is IVF & ICSI for?
Candidates for treatment
IVF and ICSI are highly effective assisted reproductive technologies suitable for a wide range of fertility challenges. Whether you are facing specific medical factors or seeking to grow your family through advanced science, these treatments offer the highest success rates in modern reproductive medicine.
Female factors
- Blocked or damaged fallopian tubes
- Endometriosis (moderate to severe)
- Polycystic Ovary Syndrome (PCOS)
- Advanced maternal age
- Reduced ovarian reserve
When IVF may not be recommended
While IVF is a versatile tool, it may not be recommended for individuals with severe medical conditions where pregnancy poses a high risk, or for those with absolute uterine factors where surrogacy is a more appropriate path. Our clinicians will conduct a thorough health assessment to ensure any treatment plan is safe and medically viable for your specific circumstances.
Male factors
- Low sperm count (oligospermia)
- Poor sperm motility or morphology
- Previous vasectomy
- Need for ICSI due to fertilisation issues
- Ejaculatory dysfunction
Combined or other factors
- Genetic screening (PGT-A/PGT-M/PGT-SR)
- Unexplained infertility
- Same-sex couples or single parents
- Repeated treatment failure (IUI)
- Immunological factors
How it works
The IVF & ICSI process
A standard IVF cycle takes 4–6 weeks from first consultation to embryo transfer. International patients typically require two visits to Bangkok. Each step is monitored and adjusted based on your individual response.
Step 1 · Initial consultation & fertility assessment
Your doctor reviews your full medical history, previous treatment records, and current health. Blood tests (AMH, FSH, oestradiol) and transvaginal ultrasound are performed — typically on cycle days 2–4. Your partner provides a semen sample for analysis. Results are reviewed the same day.
Duration: 1 day · Can be done locally and sent to ABC in advance
Step 2 · Ovarian stimulation
Based on your assessment, your doctor prescribes a stimulation protocol tailored to your ovarian reserve and response history. Hormone injections (gonadotropins) are administered daily for 8–12 days. During this period, you attend 3–4 monitoring appointments — ultrasound and blood work — so your doctor can adjust dosage in real time.
Duration: 8–12 days · Monitoring every 2–3 days
Step 3 · Egg retrieval & sperm collection
When follicles reach target size (typically 18–20mm), a trigger injection is administered. Egg retrieval is performed 34–36 hours later under light sedation. The procedure takes approximately 15–30 minutes — a minor outpatient procedure with no incision and no stitches. A board-certified anesthesiologist is present for all retrievals.
Duration: ~30 minutes · Rest 1–2 hours post-procedure
Step 4 · ICSI fertilisation & embryo culture
On the same day as retrieval, your partner provides a fresh sperm sample (2–4 days abstinence recommended). Our embryologists select individual sperm and inject one directly into each mature egg using ICSI. Fertilised eggs are cultured in our controlled-environment laboratory for 3–5 days, monitored daily for development. The target is blastocyst stage (day 5).
Duration: 3–5 days · Lab: cleanroom protocols, VOC-controlled, temperature-stable
Step 5 · Embryo transfer or freeze
If a fresh transfer is planned, one embryo is transferred to the uterus on day 3 or day 5 — a painless procedure taking 10–15 minutes, no anaesthesia required. If PGT-A testing is requested, or if your doctor recommends a freeze-all strategy, all embryos are vitrified (flash-frozen) and transfer is scheduled in a subsequent cycle after results and endometrial preparation.
Fresh transfer: same cycle · Frozen transfer (FET): typically the following menstrual cycle
Step 6 · Pregnancy test & follow-up
A blood pregnancy test (beta-hCG) is performed 10–14 days after transfer. Your doctor reviews the result with you and outlines next steps — whether continuing progesterone support, scheduling an early ultrasound, or discussing options if the result is negative.
Pregnancy confirmation ultrasound: ~2 weeks after positive test

Our results
Lab performance metrics
These are operational KPIs tracked across our laboratory network. They measure what happens inside the lab — fertilisation, embryo development, and cryopreservation survival — not pregnancy outcomes, which depend on multiple patient-specific factors.
Fertilisation rate · 84.4%
The percentage of mature eggs that successfully fertilise after ICSI. International benchmarks range from 70–80%. Our rate reflects consistent embryologist technique and sperm selection protocols.
Blastocyst formation · 72%
The percentage of fertilised eggs that develop to blastocyst stage (day 5). International average is 40–60%. This is a direct measure of lab culture conditions — air quality, temperature stability, and media quality.
Vitrification survival · 96.3%
The percentage of frozen embryos that survive the thaw process intact. This reflects cryopreservation technique and consistency. International average: 85–95%.
Why we report lab metrics, not "success rates"
Pregnancy rates depend on age, diagnosis, embryo quality, uterine factors, and transfer decisions — variables outside the lab. Reporting a single "success rate" without defining the cohort, denominator, and time period is misleading. We report what we control: lab performance.
