Shawn Zimmerman, PhD, HCLD (ABB) is the Lab Director for Vios Fertility Institute St. Louis/CRMW and strives to help patients achieve their dreams of having a family. He holds both a Master’s of Science and Doctorate in Reproductive Physiology with a focus on molecular pathways and continues to help advance our understanding of human reproduction. Dr. Zimmerman is certified as a High-complexity Clinical Laboratory Director (HCLD) by the American Board of Bioanalysis (ABB) after meeting the educational, experience, and examination requirements.
His primary interest is determining what sequence of events allows for proper fertilization in the human body. His research has focused on what parts the sperm plays during the process of fertilization and how this understanding can help infertility couples. He has written several scientific papers on how sperm are able to bind and properly fertilize eggs in vivo and continues to research this area of human reproduction.
Dr. Zimmerman works side by side with the physicians to provide the best experience possible for each and every patient that comes for treatment.
