A groundbreaking advancement in fertility treatment may transform the way fallopian tube blockages, a major cause of infertility in women, are addressed.

Researchers at the Shenzhen Institute of Advanced Technology (SIAT) in Shenzhen, China, have developed a magnetically-powered robotic microscrew to clear these blockages. It offers a less invasive alternative to traditional surgical methods involving catheters and guidewires.

The microrobot, crafted from non-magnetic photosensitive resin and coated with a thin iron layer, gains magnetic properties that enable precise navigation.

Controlled by an external magnetic field, the tiny device rotates, creating a vortex that propels debris away and effectively clears simulated blockages in a glass channel mimicking a fallopian tube. This innovative design features a screw-shaped body for propulsion and a disk-shaped tail for stability.

These Chinese scientists aim to refine their invention further, making it smaller and integrating real-time imaging systems for improved tracking.

Haifeng Xu, the study’s author and SIAT member, highlighted the technology’s potential: “This new approach offers a minimally invasive solution for patients suffering from infertility.”

With infertility affecting 186 million people globally, and fallopian tube obstructions accounting for up to 67% of female cases, this innovation represents a promising step forward in reproductive healthcare. It also offers possible applications in other surgical procedures.
