At Leeaf, we strive to innovate through science utilizing modern technology transparently and ethically.

Our research contributes to the field of artificial reproduction through dedicated research projects as well as independent, standardized, and anonymized data collection.

To contribute to the improvement of fertility treatment outcomes on a larger scale, the Leeaf research team is currently conducting a study to verify the effectiveness of data and AI-driven treatment personalization in increasing pregnancy and take-home baby rates for infertile couples.

Simultaneously, our continuous data collection seeks to reveal how lifestyle changes initiated and tracked through women‘s lifestyle wearables impact IVF results.

Principles of Ethical AI

Leeaf’s Ethical AI Principles are based on the latest thought leadership of global technology and consulting companies. We acknowledge that algorithms augment the capabilities of doctors to produce better results, together. Final decision making stays with the patient and should always be based on doctors' treatment guidance and approval. The data provided always belongs to the patient, with algorithms and technology remaining transparent, explainable, fair, and auditable at any time.
