Brief summary
Embryo transfer is the final process in the highly technical treatment of IVF. It is performed via the cervix and the embryo is placed into the uterine cavity via a fine catheter. Studies demonstrate that pregnancy rates are better when embryo transfer is performed under ultrasound guidance. Studies have also looked at the position of the bubble(fluid containing the embryo) on ultrasound following embryo transfer, with a sweet spot at 15mm from the fundal endometrium. Currently in most clinics ultrasound guidance is not performed by a person formally trained in pelvic ultrasound. The ultrasound probe is often positioned by the doctor and held by the patient whilst the doctor performs the transfer. The researchers hypothesize that performing the transfer with a trained sonographer will lead to a higher number of embryos being in the best position in the uterine cavity. We hypothesize that as compared to a patient holding the ultrasound probe, the sonographer is skilled at locating the endometrium, dynamically adjusting the probe and guiding the doctor to place the embryo in the ideal position. This study will assess the distance of the bubble from the fundal endometrium immediately following embryo transfer.
Interventions
Sonographer guided embryo transfer - the sonographer holds the abdominal ultrasound probe and guides the doctor to correctly position the embryo transfer catheter. Following embryo transfer the sonographer measures the distance of the bubble(fluid with embryo in it) from the fundal endometrium. This will potentially add on 1-2 minutes to the procedure which takes approximately 5 minutes. A picture with the bubble and measurement will be printed and the data will be entered by an independent research nurse.
