Background and aim: Organophosphate insecticide diazinon is used in agriculture and may affect fertility of men due to the production of free radicals. Because of the antioxidant properties of black currant compounds, the effect of hydroalcoholic extract of black currant on spermatogenesis in diazinon-induced toxicity in male rats was investigated.

Methods: In the present experimental study, 30 adult male Wistar rats were divided into six groups: control group without sham, corn oil and saline without intervention; the positive control group received Diazinon poison at a concentration of 16 mg / kg. Experimental 1 and 2 respectively received diazinon poison (16 mg / kg) and black and white extract (100 mg / kg) and 200 mg / kg (3 mg / kg) extract, respectively. They received 3 extracts of black currant with a concentration of 200 mg / kg. All treatments were carried out for 2 months in gavage. After 2 months sperm parameters, number, mobility, life and morphology were investigated. Similarly, testicular tissue was stained with Hematoxylin Eosin for evaluation of spermatogenesis after cutting. Data were analyzed by one-way ANOVA and Tukey's post hoc test.

Results: Diazinon with a concentration of 16 mg / kg caused a significant decrease in the number and motility of the sperm in comparison to the sham group (p <0.01) (p <0.001), but significantly altered sperm motility and morphology compared to the group Did not have you The group that received diazinon and extract of black currant with two concentrations of 100 and 200 mg / kg compared to diazinon group showed a significant increase in the number of sperms (p <0.01) (p <0.001), but blackheads caused a significant change Sperm motility was not present in the presence of diazinone. Histological examination showed that the number of primary spermatocyte cells and spermatid in the diazinone group compared to sham group decreased significantly (p <0.05). However, the number of spermatogonia cells, primary spermatocytes and spermatid in experimental groups 1 and 2 showed a significant increase compared to diazinon group (p <0.05). In the experimental group 3, the extract increased the number of sperm in comparison with the sham group (p <0.05), but did not change the testicular tissue.

Conclusion: The results indicated that black currant extract had a protective effect on testicular tissue and could increase spermatogonia, spermatocyte, spermatid and sperm count in diazinon-induced toxicity but did not affect sperm motility.
