What should you know about embryo transfer technology?

The laboratory prepares the embryo while the clinical team prepares the uterus and confirms the transfer plan. During the procedure, a soft catheter passes through the cervix into the uterine cavity. Ultrasound can help the clinician view the uterus and guide placement. The embryo is released from the catheter, which is then removed. The equipment supports accurate placement, but it cannot guarantee implantation or pregnancy.

Follow the clinic’s instructions about medicines, bladder preparation, arrival time, and food or drink. Tell the team about allergies, bleeding, pain, or difficulty with previous cervical procedures. Afterward, take prescribed treatment on schedule and follow the activity advice given for your protocol. You may return home the same day, with arrangements for the pregnancy test. See [IVF](/treatments/fertility-and-assisted-reproduction/ivf/) for the wider treatment context and [Micronised Progesterone](/materials/micronised-progesterone/) for one type of hormonal support.

Call the clinic about worsening pain, heavy bleeding, fever, unusual discharge, or feeling unwell after transfer. Urgent assessment is needed for severe pelvic pain, fainting, or breathing difficulty. Mild pressure or short-lived cramping may occur, but your own clinic can interpret symptoms alongside the procedure and your medical history.

Ask whether ultrasound guidance will be used, how the catheter route is chosen, what you should do if the bladder is uncomfortable, and when the pregnancy test is planned. Ask who to contact outside clinic hours.
