- Gather any previous fertility test results or treatment records from your doctors at home
Medication & Lifestyle Preparation
Start these lifestyle and medication adjustments at home before your trip
- Stop smoking — ideally at least 3 months before treatment (benefits both partners)
- Limit alcohol consumption while preparing for treatment
- Stop anti-inflammatory pain relievers (like ibuprofen or naproxen) 7 days before egg retrieval — discuss with your doctor at home
- Stop herbal supplements 2 weeks before treatment begins — ask your clinic which ones to avoid
- Review all current medications with your doctor at home — some may need adjusting before treatment
Connect with Your Thai Clinic
Get your treatment plan confirmed and questions answered before you travel

Frequently Asked Questions
How is ICSI different from conventional IVF?
In conventional IVF, eggs and sperm are mixed together and fertilization occurs naturally. With ICSI, a single sperm is selected and injected directly into each egg using a fine glass needle. ICSI bypasses natural sperm selection, making fertilization possible even with severely compromised sperm quality.
What are the success rates for ICSI?
Fertilization rates are 70-85% per injected egg. Live birth rates depend on age: 50-60% for women under 35, 40-50% for ages 35-37, 30-40% for ages 38-40, and 15-25% for ages 41-42. With PGT-tested embryos, rates can reach 60-70%. Individual outcomes vary based on multiple factors.
Is ICSI safe for the baby?
Over 95% of ICSI children are born without major abnormalities. Physical growth and neurodevelopment appear normal through age 12 in long-term studies. There is a slightly elevated rate of birth defects compared to natural conception, though it's difficult to separate technique effects from underlying parental infertility factors.
How long do I need to stay in Thailand for ICSI treatment?
A typical ICSI cycle requires 4-6 weeks. Initial consultation and testing take 1-2 days, ovarian stimulation requires 10-14 days of daily monitoring, followed by egg retrieval, fertilization, and embryo transfer. Plan to stay at least 2 weeks after transfer for the pregnancy blood test.
Can foreigners receive ICSI treatment in Thailand?
Yes, IVF/ICSI is available to legally married heterosexual couples. You will need a marriage certificate (foreign couples need legalized/apostilled documents) and both partners must consent to treatment. Thai clinics regularly treat international patients from over 190 countries.
Intracytoplasmic Sperm Injection (ICSI) is an advanced fertilization technique performed within an IVF cycle where a single sperm is injected directly into a mature egg using a fine glass micropipette. Developed in 1992, ICSI has become the most successful treatment for male factor infertility and is now utilized in approximately 60% of all IVF procedures worldwide.
Unlike conventional IVF where sperm and eggs are mixed and fertilization occurs naturally, ICSI bypasses natural sperm selection by directly inserting a single carefully selected sperm into the egg’s cytoplasm. This makes fertilization possible even with severely compromised sperm quality, including cases where sperm must be surgically retrieved.
When ICSI Is Recommended
Thai fertility specialists typically recommend ICSI for:
- Severe male factor infertility — Very low sperm count, poor motility, or abnormal morphology
- Surgically retrieved sperm — When sperm is obtained through TESE, PESA, or MESA procedures
- Previous IVF failure — Cases of total or poor fertilization in prior conventional IVF cycles
- Limited egg availability — When few eggs are retrieved and maximum fertilization is crucial
- Preimplantation genetic testing — ICSI is required to prevent DNA contamination during embryo biopsy
Treatment Timeline
A typical ICSI cycle follows this timeline:
- Ovarian stimulation (Days 1-14): Daily hormone injections with regular monitoring
- Trigger shot (Day 12-14): hCG or GnRH agonist to trigger final egg maturation
- Egg retrieval (36 hours post-trigger): Transvaginal ultrasound-guided procedure (15-20 minutes)
- ICSI fertilization (Same day): Each mature egg is injected with a single selected sperm
- Embryo culture (Days 1-6): Embryos develop in the laboratory
- Embryo transfer (Day 5-6): Best blastocyst(s) transferred to the uterus
- Pregnancy test (Day 10-14 post-transfer): Blood hCG test confirms pregnancy
