Klaus Wiemer Ph.D.


Dr. Klaus Wiemer received his Masters degree in Reproductive Physiology with an emphasis in Male Physiology from New Mexico State in 1985. Subsequently in 1989, he received his PhD in Reproductive Physiology with an emphasis in Embryology from Louisiana State University (LSU).

During his studies at LSU, Klaus developed many new culture methods, one of which mimics the uterine/fallopian tube environment and allows embryos to be placed on a layer of cells originally found in the uterus or fallopian tubes. In 1988, he was awarded the overall Grand Prize by the American Society for Reproductive Medicine when studies using this co-culture system in assisted reproduction with human IVF showed increased pregnancy rates. Dr. Wiemer was also one of the first embryologists in the US to achieve pregnancies with human blastocysts.

Having successfully directed several IVF programs in the United States, he ran a program in North Carolina producing one of the highest pregnancy rates in the country, with delivery rates of 55% and implantation rates of 22%. Blastocyst culture and transfer resulted in a 62% delivery rate.

In addition to his clinical responsibilities, Dr. Wiemer conducts research in a variety of areas, including the developmental potential of human embryos through variations in human embryo culture media, exploration of the relationship between embryo morphology and pregnancy rates, and the study of follicular stimulation and its effects on initial follicular dynamics and oocyte and embryo quality.

Dr. Klaus Wiemer is a frequent speaker at professional meetings, both across the US and internationally. He received the LIFE Award for Laboratory Innovations in Fertility and Embryology.
