Protective and restorative potency of diosmin natural flavonoid compound against tramadol-induced testicular damage and infertility in male rats

Flavonoids are polyphenolic natural compounds with various biological actions and limited toxicity including diosmin (DM) which is considered a safe flavonoid natural type with anti-inflammatory and antioxidant activities. Tramadol (TM) is a centrally long-acting analgesic class of opioids extensively being used among the population. It was reported that long-term exposure to TM triggers the releases of oxidative stress, inflammatory factors, and nitric oxides resulting in organs damage. This study aimed to investigate the possible ameliorative and restorative actions of DM against tramadol-induced testicular damage. Rats were divided into: GI: control; GII: Rats received TM, GIII: Rats received DM, GIV: Rats received TM + DM; GV: Rats received DM + TM. Rat's testicular tissue and blood samples were collected. A relevant improvement in all examined parameters was observed among GIV and GV groups. Thereby, it was highlighted that diosmin has beneficial natural actions against tramadol-induced testicular injury via suppressing triggered oxidative stress, and inflammatory factors.
