**About the Special Issue Editor**

**Cristian O'Flaherty** received a DVM and Ph.D. degrees from the University of Buenos Aires, Argentina. He completed his postdoctoral training in sperm physiology and toxicology at McGill University. Dr. O'Flaherty is an associate professor in the Department of Surgery (Division of Urology) and an associate member of the Department of Pharmacology and Therapeutics, at the Faculty of Medicine, McGill University. He is also a medical scientist at the Research Institute of the McGill University Health Centre. Dr. O'Flaherty is the Co-Director of the McGill Centre for Research in Reproduction and Development. He is serving as associate editor of Andrology and a member of the Editorial Board of Biology of Reproduction. His research program focuses on male reproduction, particularly on the molecular mechanisms involved in the production and function of healthy spermatozoa, sperm activation and the role of reactive oxygen species in sperm physiology and toxicology. His current work includes the use of mouse models and clinical studies in infertile men to elucidate the role of peroxiredoxins in the regulation of sperm function using genomic, proteomic and biochemical approaches. Moreover, Dr. O'Flaherty's laboratory is working on the molecular mechanism that drives the formation and function of the acrosome and developing novel diagnostic and therapeutic tools for infertile men. His research program has been and is currently funded by different agencies, including the Canadian Institutes of Health Research, FRQS and the Fonds de Recherche Nature et technologies.
