The study investigated the effects of Heracleum persicum L. extract (HPE) on oxidative damage caused by mercuric chloride (HgCl₂) in rat testes. Sixty male Wistar rats were divided into six groups: a sham group, a HgCl₂ group, three groups receiving HgCl₂ with HPE at doses of 250, 500, and 750 mg/kg, and a control group treated with 750 mg/kg HPE alone over 50 days. HgCl₂ was administered intraperitoneally for the first 10 days, followed by HPE gavage for 40 days.
