At a glance
A clear, step-by-step overview of the embryo transfer procedure in Thai clinics, including preparation, the transfer day, recovery, and what to ask your doctor.
Understanding the Embryo Transfer Procedure
An embryo transfer is the final step in an IVF cycle, where a carefully selected embryo is placed into the uterus. In Thailand, the procedure is typically performed in an outpatient setting and does not require anesthesia. The transfer itself is quick, but the preparation and monitoring beforehand are important for timing and success.
Preparing for Transfer Day
Medication and Hormonal Support
Before the transfer, you will take medications to prepare the uterine lining. These may include estrogen and progesterone, given as pills, injections, or vaginal suppositories. The exact regimen depends on whether you are using a fresh or frozen embryo transfer (FET) and your individual cycle. Your clinic will provide a schedule and instructions.
Lifestyle and Diet
Your clinic may recommend avoiding alcohol, caffeine, and smoking in the weeks leading up to transfer. A balanced diet and adequate hydration are generally advised. Some clinics suggest avoiding vigorous exercise, but confirm specific recommendations with your doctor.
Bladder Preparation
For the transfer, you will be asked to have a moderately full bladder. This helps the doctor visualize the uterus clearly on ultrasound and facilitates catheter placement. You will typically be instructed to drink water about one hour before the procedure.
The Transfer Day: Step by Step
- Check-in and identification: You will confirm your identity and the embryo details with the clinic staff.
- Ultrasound guidance: The doctor uses abdominal ultrasound to view the uterus and guide the transfer catheter.
- Speculum placement: A speculum is inserted into the vagina to visualize the cervix.
- Cervical cleaning: The cervix may be gently cleaned with a sterile solution.
- Catheter insertion: A thin, flexible catheter containing the embryo is passed through the cervix into the uterine cavity.
- Embryo release: The embryo is gently expelled into the uterus, usually in a small drop of fluid.
- Catheter removal: The catheter is withdrawn slowly.
- Rest period: You may be asked to lie still for 10–30 minutes. Some clinics recommend a short rest before discharge.
The entire procedure typically takes 15–30 minutes. Most patients describe mild discomfort similar to a Pap smear.
Recovery and Post-Transfer Care
After the transfer, you can resume normal activities the next day, but your clinic may advise avoiding strenuous exercise, heavy lifting, or sexual intercourse for a few days. Continue taking prescribed medications as directed. Mild cramping or spotting can occur and is usually normal. Contact your clinic if you experience severe pain or heavy bleeding.
What to Ask Your Clinic
- What is the recommended medication schedule before and after transfer?
- Should I have a full bladder for the procedure?
- How long should I rest after transfer?
- What symptoms should I report immediately?
- When will the pregnancy test be scheduled?
Next Steps After Transfer
Your clinic will schedule a blood test (beta-hCG) approximately 10–14 days after transfer to determine if pregnancy has occurred. Until then, try to maintain a calm routine and avoid stress. Follow your clinic’s instructions and attend all follow-up appointments.
