Andrology, Volume 13, Issue 6, Page 1601-1614, September 2025.Abstract Background Ascorbic acid 2‐glucoside (AA2G) is a stabilized form of ascorbic acid and a potent antioxidant. Ascorbic acid is present in the testes and epididymis and helps maintain the physiological integrity of reproductive organs. Its properties have been utilized to protect spermatozoa of different species from oxidative stress.
