Wayne Beyer, MD is a retired ophthalmic surgeon, graduate of Cornell University and the University of Pennsylvania School of Medicine. Says Beyer, "I was exposed to DES in utero in 1951 and subsequently developed a host of congenital anomalies, urogenital and psychological problems. I consider myself intersexed, both genitally as well as neurologically, and have begun my transition from living as a man to living as a woman. I discovered my exposure to DES in the 1980's after searching for decades to discover the cause of my gender 'confusion.' I came across the DES Sons website in 2000, hooked up with Scott Kerlin and have grown into the position of co-moderator and resident medical expert for the list. I am actively pushing the Sons' interests with various political and research groups, trying to bring the scientific, medical and environmental communities together to head off the burgeoning endocrine disruptor crisis.
