Embryo transfer procedure for In Vitro Fertilization (IVF)
22 May 2025Embryo transfer procedure for In Vitro Fertilization (IVF)
Embryo transfer is one of the most critical and delicate steps in the In Vitro Fertilization (IVF) process. It marks the moment when the embryo, created in the laboratory, is carefully placed into the uterus with the hope of achieving a successful pregnancy. Every step of this process is handled with precision and care to ensure the best possible outcome for those undergoing fertility treatment.
In this blog, we’ll guide you through everything you need to know about the embryo transfer procedure, from preparation to post-transfer care.
What is embryo transfer?
Embryo transfer is the final stage of the IVF cycle, where one or more embryos are placed into a woman’s uterus with the goal of achieving pregnancy. This procedure is typically painless, quick, and performed under ultrasound guidance.
When is embryo transfer done?
Embryo transfer is usually done either:
- On day 3 (cleavage stage) after egg fertilization, or
- On day 5 (blastocyst stage) when the embryo has developed further.
The timing depends on the embryo quality, patient’s age, previous IVF history, and medical judgment of the fertility specialist.
Types of embryo transfers
- Fresh embryo transfer
The embryo is transferred in the same cycle as the egg retrieval.
- Frozen Embryo Transfer (FET)
Embryos are frozen and transferred in a later cycle. FET allows better hormonal preparation and improved success in some cases.
- Single vs. Multiple embryo transfer
Based on age and embryo quality, doctors may transfer one (Single Embryo Transfer – SET) or more embryos to improve success rates.
Step-by-Step embryo transfer procedure
1. Endometrial preparation
For a successful implantation, the uterine lining (endometrium) must be receptive. This is achieved by:
- Hormonal support using estrogen and progesterone.
- Regular ultrasound monitoring to check endometrial thickness (ideally 7–12 mm).
2. Embryo selection
Embryologists carefully select the best quality embryo(s) using:
- Morphological grading.
- Advanced techniques like time-lapse imaging or PGT (Preimplantation Genetic Testing), if indicated.
3. Embryo thawing (in FET cycles)
If using frozen embryos, they are thawed a few hours before transfer using a precise warming protocol to maintain viability.
4. The transfer procedure
- The patient lies on a gynecological table.
- A speculum is placed to visualize the cervix.
- A soft, thin catheter loaded with the embryo(s) is gently passed through the cervix into the uterus.
- The embryo is placed about 1–2 cm from the top of the uterine cavity under ultrasound guidance.
- The procedure takes about 10–15 minutes and is usually painless (no anesthesia required).
5. Post-transfer rest
While strict bed rest is not necessary, we recommend patients rest for 15–30 minutes post-procedure and avoid strenuous activity for a few days.
Post-embryo transfer care
Medication support:
- Progesterone supplements (oral, vaginal, or injectable) to support implantation.
- Other supportive medications as prescribed.
Activity guidelines:
- Avoid heavy lifting, intense exercise, and intercourse for at least 7–10 days.
- Maintain a healthy, relaxed lifestyle.
Diet & Hydration:
- Eat a balanced diet rich in fiber, protein, and fluids.
- Avoid caffeine, alcohol, and smoking.
Emotional support:
- It’s normal to feel anxious during the two-week wait.
- Engage in light activities and stay positive.
When to take a pregnancy test?
A blood test for beta-hCG is usually scheduled 10–14 days after the embryo transfer to confirm pregnancy. Avoid taking home urine pregnancy tests too early, as they may give false results.
Success rates of embryo transfer
Success depends on multiple factors including:
- Age of the woman.
- Quality of the embryo.
- Endometrial receptivity.
- Cause of infertility.
Advanced laboratory technology and personalized care plans are used to maximize the chances of success during the IVF process. Each patient’s treatment is tailored to their unique needs to help achieve the best possible outcome.

FAQs
While some women may notice symptoms like mild cramping or breast tenderness, there are no definitive signs of success until a beta-hCG blood test confirms pregnancy.
Short-distance, non-strenuous travel is generally safe, but it’s best to avoid long journeys, flights, or bumpy rides in the first few days after transfer unless approved by your doctor.
Wear comfortable, loose-fitting clothes. You may be asked to come with a full bladder for better ultrasound guidance during the transfer.
If implantation does not occur, your fertility specialist will review the cycle and may adjust the protocol or investigate further causes before planning the next steps.
While lifestyle factors help, implantation mainly depends on embryo quality and endometrial receptivity. Avoid stress, stay hydrated, and follow medical advice.
Yes, most patients can return to work the next day unless their job involves heavy physical exertion or extreme stress.
Some women may experience light spotting, mild cramps, or bloating, which can be normal. However, many successful implantations happen without any noticeable symptoms.
