New research advancements in the treatment of premature ovarian failure

Scientific Director of the Meharry Center for Women's Health Research and a team of researchers from the University of Texas Medical Branch and the University of Saskatchewan have recently discovered that the gene mutation believed to be a possible cause of premature ovarian failure may be corrected when an adenovirus compensating for the mutated gene is introduced. Findings were reported in the recent issue of Molecular Human Reproduction.
