                                Human seminal fluid is a high-fructose environment, with average concentrations around 15 mM—more than 300 times higher than fructose levels typically found in blood. Understanding the specific sugars, and exactly how much sugar is in seminal fluid, is key to comprehending male reproductive health and sperm function.
