In the first installment of our multi-part series on Peyronie's disease, Dr. Mills explains what causes the condition, how it can change the shape, length and function of the penis, and why it may be far more common than most men realize. He also traces its unusual medical history, separates Peyronie's from congenital curvature and dispels the damaging idea that patients somehow caused it themselves. From medications and traction devices to injections and surgery, Dr. Mills previews the range of treatments that will be explored throughout the series. Most importantly, he addresses the condition’s profound psychological impact and offers reassurance that effective options are available—and that no one should suffer in silence.
