Compounds such as chrysin inhibit the effects of toxic substances such as diazinon on visceral organs and the present study was performed to evaluate the protective effect of chrysin on spermatogenesis by interfering with diazinon toxin. In this experimental study, 42 male Wistar rats weighing approximately 250-180 g were selected and randomly divided into 7 groups including control, sham, diazinon with a concentration of 20 mg/kg BW, chrysin with a concentration of 10, Chrysin with a concentration of 20 mg/kg, chrysin with a concentration of 10 mg/kg and diazinon with a concentration of 20 mg/kg and chrysin with a concentration of 20 mg/kg and diazinon with a concentration of 20 mg/kg were divided. At the end of the treatment period, with the process of tissue preparation, with Motic software, the number of cell lines per unit area was determined and compared with each other in different groups. There was a significant difference between the mean number of sperm count and sperm motility in the Sham and Control groups with Diazinon and DC10 groups (p < 0.001), and DC20 groups (p < 0.01). Also, there was a significant difference in sperm mortality in Shm and Cnt groups with Diazinon, DC10 and DC20 test groups (p < 0.001). The results showed that there was a significant difference in the mean number of sperm count, sperm motility, sperm mortality, sperm morphology, number of Leydig cells, number of germ cells, number of primary and secondary spermatocytes, and number of spermatids in Sham and Control groups compared to some test groups. Thus, CHR as a potent antioxidant can compensate for the toxicity of Diazinon toxin.

Regarding the possible role of Diazinon (DZN) to induce free radicals production, it is assumed that it can lead to increased level of lipid peroxidation and then poor sperm quality. In this research, we aimed to investigate the toxic effects of DZN on sperm parameters quality as well as lipid peroxidation level in sera and seminal plasma of male rats. In this experimental research, 24 male rats (Balb/c) were randomly divided into four groups including: controls (n=6), treatment group A (n=6), treatment group B (n=6) and treatment group C (n=6). Commercial DZN was injected orally in a single dose (A=5mg/kg, B=10mg/kg and C=25mg/kg per day). After 5 weeks, animals were sacrificed for Malondialdehyde (MDA) and parameters quality examinations using Thiobarbituric acid reaction (TBAR) and microscopic techniques, respectively.  There was a significant reduction in sperm parameters quality in treatment groups, especially in group C and group B, when compared with controls (p<0.001). There was a significant difference for serum and seminal plasma MDA mean levels between study groups of A, B, C and control groups (p<0.001).  DZN leads to poor sperm quality via increasing of serum and seminal lipid peroxidation levels in a dose dependent manner.
