In vitro fertilization is a crucial step in the journey of many couples wishing to have children. However, to increase the chances of success with this technique, innovation is essential. It is with this perspective that the use of revolutionary microrobots emerges as a promising solution. Indeed, these cutting-edge technologies improve the precision and efficiency of in vitro fertilizations, thereby offering new prospects for the conception of a long-awaited baby.
A revolutionary technological advance
In 1982, France witnessed the birth of its first child from an in vitro fertilization (IVF). Forty years later, despite considerable progress, the success rate of IVF remains variable, ranging from 13% to 46%. Several factors can influence these results, including the age and health of the parents, but a major cause lies in the very manipulation of the gametes.
The challenge of manual manipulations
Currently, the IVF process remains primarily “manual.” Technicians use pipettes to handle eggs and sperm, requiring great dexterity and precision. Sinan Haliyo, a professor at the Institute of Intelligent Systems and Robotics (ISIR – CNRS/Sorbonne University), emphasizes that this process is not only demanding but also prone to human errors.
The innovation of microrobots
To standardize and improve this practice, a team of researchers from the CNRS has developed microrobots capable of manipulating gametes with unparalleled precision. These tiny robots, controlled remotely via a joystick, faithfully reproduce the perceived resistances, allowing for delicate and safe handling of reproductive cells.
The benefits of technology
The use of these microrobots presents several significant advantages:
- Increased precision: Microrobots allow for millimeter-precision manipulation of gametes, reducing the risk of damage.
- Controlled environment: Fertilization takes place in a closed environment, ensuring total control over surrounding conditions and increasing the chances of success.
- Facilitation of identity vigilance: This technique minimizes the risks of cross-contamination and identification errors.
Promising prospects
After a decade of academic research, the project is ready to take a new step: the creation of a start-up named Movalife. This young company, still in the construction phase, is currently seeking funds to finance preclinical trials.
By integrating microrobots into the in vitro fertilization process, we are witnessing a true technological revolution. This innovation promises not only to significantly improve the success rates of IVF but also represents a major advance in the field of assisted reproductive technology. The coming years will be crucial to see how this technology can transform the hopes of many couples into reality.
