Leeaf conducts prospective observational research study

Starting January 2023, Leeaf is conducting a prospective, multi-centric, international research study with richer than ever four-dimensional patient data (medical, lifestyle, environmental, and genetic) to allow scientists to look deeper into factors that may influence the outcomes of controlled ovarian stimulation.

Building on several previously completed scientific studies on artificial intelligence in IVF, this observational study collects data to develop and fine-tune Leeaf’s algorithms, which will support IVF specialists in treatment selection through the Leeaf Physician Portal. The subsequent randomised control trial (RCT) will prove the efficacy of the proposed algorithms and models. First observations will be available in March, with first conclusions expected by the end of June.

To date, Leeaf has assembled an international scientific board consisting of high-profile IVF experts across the Czech Republic, Hungary, Spain, the United Kingdom, and the United States to oversee the strategic direction of Leeaf's research efforts.

The study is conducted under the supervision of Jan Choma, Co-Founder and Co-CEO of Leeaf, who oversees research activities and coordinates the medical and scientific boards.
