The embryo transfer is one of the most critical and final steps of the IVF (In Vitro Fertilization) process. Here’s a clear and step-by-step explanation of how it’s done:
🔬 What is Embryo Transfer?
It is the procedure where one or more embryos (fertilized eggs) are placed into a woman’s uterus to achieve pregnancy.
🧪 Steps of Embryo Transfer Process:
1. Embryo Selection
- After fertilization, embryos are cultured in the lab for 3 to 5 days.
- The best quality embryo(s) are selected for transfer based on their growth and appearance.
- Sometimes genetic testing (PGT) is done to choose the healthiest embryo.
2. Timing
- The transfer is usually done on Day 3 (cleavage stage) or Day 5 (blastocyst stage).
- Your fertility specialist decides the best day based on your case.
3. Preparing the Uterus
- The uterine lining (endometrium) must be thick and receptive.
- Hormonal support (estrogen and progesterone) may be given to prepare the lining.
4. The Embryo Transfer Procedure
- It’s a painless, non-surgical, and outpatient procedure.
- The woman lies on an examination table, similar to a pelvic exam.
- A speculum is inserted into the vagina to visualize the cervix.
- A soft, thin catheter is loaded with the embryo(s).
- Using ultrasound guidance, the catheter is gently inserted through the cervix into the uterus.
- The embryo is carefully deposited into the uterine cavity.
5. After the Transfer
- The woman may be asked to lie down for 10–30 minutes (depending on the clinic).
- No anesthesia is needed, and normal activities can often be resumed the same day.
- Hormonal support is continued.
🩸 What Happens Next?
- Around 10 to 14 days after the transfer, a pregnancy test (beta hCG) is done to check for implantation.
🧘♀️ Tips for Success:
- Avoid stress.
- Follow all prescribed medications.
- Refrain from smoking, alcohol, and heavy exercise.
