Oxidative stress (OS) has been identified as one of the many mediators of male infertility by causing sperm dysfunction. Excessive production of free radicals or reactive oxygen species (ROS) can damage sperm, and ROS have been extensively studied as one of the mechanisms of infertility. Spermatozoa are sensitive to OS because they lack cytoplasmic defenses (Donnelly et al, 1999; Saleh and Agarwal, 2002). No wonder sperm counts are crashing the world over.
Oxidative stress increases significantly when we are physically or emotionally stressed out. This is something to worry about with stress and anxiety going off the charts in the 21st century. One easy way to access this problem is by looking at the quality of our sleep and heart rate variability (HRV), which offers the best measurement of our stress.
