Abstract

Zygote transfer is a significant limiting factor in pregnancy rates after Assisted Reproductive Technology (ART) treatment. Adequate technique appraisal should be a high priority task for any medical facility that offers this treatment. Although many clinicians have extensive personal experience, it is difficult for trainees to understand the anatomical and mechanical process of safe and adequate placing of zygotes in the uterine cavity. Ultimately, even with ultrasound help, it is a "blind procedure". The experimental module described here allows for direct visualisation of the mechanical passage of a catheter through the cervix and final placement of the tip in relation to the intravaginal visible part of the catheter. It has worldwide practical applicability for trainees and experienced clinicians accompanying the theory and allowing adequate training and retraining of all staff performing zygote transfers.
