Embryo transfer refers to a step in the process of assisted reproduction in which embryos are placed into the uterus of a female with the intent to establish a pregnancy. This technique - which is often used in connection with in vitro fertilization (IVF) - may be used in humans or in other animals, in which situations and goals may vary.
Embryo transfer is the step in assisted reproduction in which one or more embryos are placed into the uterus with the intent of establishing a pregnancy, most often in connection with in-vitro fertilisation (IVF). The transfer can be performed at the cleavage stage, on day two or three of embryo development, or at the blastocyst stage, on days five to six — a technique first performed in 1984. Its success is influenced by endometrial receptivity, embryo quality and the transfer technique itself. During the procedure a speculum is placed to visualise the cervix, which is cleansed with saline solution or culture media. A transfer catheter is loaded with the embryos and, after the patient's identity is confirmed, is passed through the cervical canal and advanced into the uterine cavity, where the embryos are expelled and deposited. Several measures are supported by evidence to improve results: using a soft rather than a hard catheter, guiding the transfer with abdominal ultrasound to confirm placement about 1 to 2 centimetres from the uterine fundus, removing cervical mucus, and using transfer media enriched with hyaluronic acid. Single embryo transfers in particular require accuracy and precision in placement within the uterine cavity. Anaesthesia is generally not required, and immediate walking is possible once the transfer is complete.

Average recovery for Frozen Embryo Transfer is 0 days. Individual recovery varies — always follow your surgeon’s specific guidance.
Immediate
First 24–48 hours post-procedure. Monitoring, anaesthesia recovery, initial pain management. Most clinics expect you to remain on-site or nearby.
Early recovery
Wound care, swelling or bruising peaks, restricted activity. Typical window for follow-up visits and drain removal if applicable. Travel is usually not advised.
Intermediate recovery
Gradual return to non-strenuous daily activity. Many international patients fly home during this window. Surgeon may require medical clearance for long-haul travel.
Full recovery
Return to full activity, exercise, and work. Final results may still be settling. Final follow-up with local doctor recommended.

It is a step in assisted reproduction in which embryos are placed into the uterus of a woman with the intent of establishing a pregnancy. It is often used in connection with in-vitro fertilisation (IVF).
Transfer can be performed at the cleavage stage, on day two or three, or at the blastocyst stage, on days five to six. Blastocyst-stage transfer was first performed in 1984.
A speculum is placed to visualise the cervix, which is cleansed with saline or culture media. A transfer catheter is loaded with the embryos, and after the patient's identity is confirmed it is passed through the cervical canal into the uterine cavity, where the embryos are expelled and deposited.
Anaesthesia is generally not required for embryo transfer, and immediate walking is possible once the procedure is complete.
Success is influenced by endometrial receptivity, embryo quality and the transfer technique. Measures supported by evidence include using a soft transfer catheter, abdominal ultrasound guidance, placement about 1 to 2 centimetres from the uterine fundus, removal of cervical mucus, and transfer media enriched with hyaluronic acid.
Yes. There is good and consistent evidence that using abdominal ultrasound guidance to ensure correct placement significantly increases clinical pregnancy compared with relying on 'clinical touch' alone.
