IUI
Since 1986, Ombelet has promoted intrauterine insemination (IUI) as a cost-effective and safe method of assisted reproduction in selected cases of moderate male and unexplained infertility. He wrote many scientific papers on this subject; the most important one was published in 2018. Furthermore, with Ben Cohlen (Zwolle, the Netherlands), head of the Fertility Center Isala, he edited a book on IUI and worked on the WHO guidelines for IUI.
IVF
In 2009, a new innovative simplified IVF system was developed by Professor Jonathan Van Blerkom from the Department of Molecular, Cellular, and Developmental Biology at the University of Colorado, Boulder, USA. The simplified IVF system was tested and validated for human application in Genk resulting in 5 scientific publications showing the effectiveness and safety of the system.
In 2015, a collaborative project was started in Ghana with the support of the Pentecost Church and in close partnership with Nana Yaw Osei, Fertility Counselor & CEO of the Association of Childless Couples Of Ghana (ACCOG Ghana]).
