Lab Director, Poma Fertility

Dr. Klaus Wiemer has an extensive clinical and scientific background and experience in embryo culture, cryopreservation of embryos, embryo morphology and assessment, co-culture, blastocyst development, IVF lab design, and laboratory supervision. He has extensive experience in all aspects of clinical embryology.

He received his doctorate in Reproductive Physiology (Embryology) in 1989 from Louisiana State University, Baton Rouge, LA, USA. He trained extensively with Dr. Jacques Cohen at Cornell Medical University. Dr Wiemer has over 30 years of experience directing IVF Laboratories. He also has been an off-site director of several fertility clinics. He currently collaborates with IVF centers in Argentina and Peru.

Dr Wiemer has published over 80 peer-reviewed articles and book chapters on a wide range of topics in the area of clinical embryology. He has received numerous awards for his research, including the Overall Grand Prize awarded by the American Society for Reproductive Medicine as well as LIFE Award for Laboratory Innovation in Fertility and Embryology.

His main interests are in embryo culture systems, improving laboratory outcomes and studying the effects of follicular stimulations on subsequent oocyte and embryo quality. He is currently conducting research on developing an embryo morphology grading system that can be used to predict rate and quality of blastocyst development. He is also conducting research in the field of embryo metabolomics as well as the use of AI to predict blastocyst quality and ploidy status. Other projects include various aspects of oocyte as well as blastocyst vitrification systems.
