The present work was aimed to evaluate the protective effects of alpha‐tocopherol (α‐toco) and/or Lactobacillus plantarum (LCB) against testicular atrophy induced by mercuric chloride (MCH). Rats were injected with 5mg/kg MCH for 5 days consecutively, then treated with 100mg/kg α‐tocoand6×1010 CFU 1.8701/kg LCB alone or together for 3 weeks. The MCH elevated serum TNF‐α, IL ‐ 6, caspase‐3, and testicular malondialdehyde. However, serum testosterone, dehydroepiandrosterone, testicular messenger RNA of a steroidogenic acute regulatory protein, 17‐β‐hydroxysteroid dehydrogenase, 3β‐hydroxysteroid dehydrogenase, glutathione level, and superoxide dismutase activity were decreased. Protein expression of Nrf2 was downregulated whereas that of Bax and DNA fragmentation was upregulated in the testicular tissues. Treatment with α‐toco and LCB ameliorated the deviated biochemical parameters and improved tissue injury. It was concluded that the combination of LCB and α‐toco achieved promisingresults in the ameliorationofMCH‐induced testicularatrophy. Nrf2, Bax expressions, and DNA fragmentation are involved in the testicular atrophy induced by MCH.
