Soft Microrobot for Embryo Transfer in Assisted Reproductive Technology

Abstract

This letter proposes a novel therapeutic approach in assisted reproductive technology (ART) to control the implantation position of after embryo transfer. The system composed of a soft microrobot, a catheter, and a guiding magnet. The microrobot accommodates and transports an embryo into the patient’s uterus and keeps the embryo within the suitable area for implantation. The proposed treatment was demonstrated with the prototype in an obstetric model. This minimally invasive system will increase the pregnancy rate and prevent ectopic pregnancy.
