Embryo transfer (ET) is a critical step in IVF procedures, representing the culmination of meticulous preparation and anticipation for prospective parents. The success of ET is influenced by various factors, including the technique employed during the procedure. This blog post aims to provide a comparative analysis of two commonly utilized techniques: ultrasound-guided and clinical touch. Through an exhaustive review of pertinent literature and available data, this analysis seeks to shed light on the advantages, drawbacks, and overall outcomes associated with each technique. 

Ultrasound-Guided Vs. Clinical Touch

Ultrasound-Guided Technique:

Ultrasound-guided ET offers the advantage of real-time visualization of the catheter tip within the uterine cavity, allowing for precise placement and potentially improving the accuracy of embryo deposition. This technique is particularly beneficial in cases of difficult anatomical conditions or previous ET failures. Studies have demonstrated success rates for pregnancy and live births ranging from 40% to 50% with this technique, contingent upon variables such as embryo quality and patient demographics. Nevertheless, ultrasound-guided ET might prolong the procedural duration and increase overall expenses due to the necessary specialized equipment and personnel.

Clinical Touch Technique:

On the other hand, clinical touch ET technique, relies on the tactile expertise of gynecologists to execute catheter insertion and embryo placement manually. While inherently reliant on clinical skill, this approach may offer cost-effective and accessible alternatives, particularly in resource-limited settings. However, its pregnancy and life birth rates typically range slightly lower, averaging between 25% to 35%.

The choice between ultrasound-guided and clinical touch techniques in ET with Kitazato catheters should be carefully considered based on individual patient characteristics, practitioner expertise, and available resources. While ultrasound-guided ET offers advantages in terms of precision and adaptability to challenging anatomical conditions, clinical touch ET remains a viable option in settings where ultrasound guidance is not readily available or feasible.
