The Embryo Transfer
- A small catheter (tube) through which the embryos are injected, is placed through the cervix into the uterus.
- Antibiotics are taken by mouth to prevent infection.
- Ultrasound is often used to help guide the placement of the catheter.
- Bed rest at home is recommended for the following day.
- Most embryo transfers are performed on the 3rd day after egg retrieval.
- Three to five of the fastest growing embryos are selected. If there are additional embryos, cryopreservation may be an option.
- Day 5 transfers are usually suggested when the patient is at great risk of high order multiple birth (triplets or more).
Day 5 Embryo Transfer
- When conception occurs naturally, the embryo arrives in the uterus at the blastocyst stage, 5-6 days after ovulation.
- Embryos in the lab that grow to the blastocyst stage are more likely to implant, allowing us to transfer fewer embryos without lowering the chance of pregnancy.
- Recommendations for day of transfer are made on an individual basis.
