Establishment of a trans‐vaginal ultrasound‐guided pinpoint transfer method

PURPOSE: Through the use of the trans‐vaginal ultrasound‐guided pinpoint transfer method, the aim was to ensure the safety of the embryo being transferred in cases of difficult cervixes. It also was aimed to be able to stop embryo transfers in difficult cases and to be able to restart the process under anesthesia or cryopreservation. METHODS: A new type of transfer catheter was developed. With this method, after reaching the internal os, the embryologist begins the loading of the embryo into the inner catheter. Then, the embryo transfer begins. Under the guidance of the trans‐vaginal ultrasonography, the optimal position for implantation is selected. RESULTS: Out of 666 cases, 14 were difficult cervixes. This transfer method enabled 221 of the 666 patients to become pregnant successfully, which was a success rate of 33.2%. CONCLUSION: From start to finish, this method takes only 2 min. It is simple, fast, and reliable, with a high satisfaction rate amongst patients.
