Probing penile hemodynamics by using photoplethysmography as objective indicators for male erection quality and sexual function
Abstract Erectile dysfunction (ED) is mostly due to the lack of blood flow into the penis.In the past 20 years, near-infrared here spectroscopy (NIRS) was used in measuring the concentrations and temporal dynamics of different hemoglobin types.However, the dynamics of the light absorption (photoplethysmography; PPG) have not been applied to survey
