Creating Sperm

Dr. Turek, who has published in the field of stem cell research, is interviewed about research findings published in 2009 that claimed to have made human sperm in a dish. He was skeptical of the results at that time and expressed this feeling, as did others. Notably, the research paper was retracted from the journal soon after this interview. Since then, Dr. Turek has obtained a grant from the National Institutes of Health (NIH) to do similar research.
