The aim of this study was to investigate the effect of different levels of peppermint extract on semen quality of Arabi rams. Semen was collected from 12 Arabi rams weekly for 8 weeks and immediately mixed, and then were divided into 5 parts and received zero, 50, 100, 150 and 200 μl/ml of peppermint extract. At different storage times of diluted semen containing treatments (zero, 24, 48 and 72 hours) in liquid condition, semen quality parameters were evaluated. Immediately after sperm collection, the lowest total motility and sperm viability belonged to the level of 200 peppermint extract (P<0.05). At 24 hours, levels 150 and 200 of extract increased the rate of morphological abnormalities of sperms. At this time, the lowest level of sperm plasma membrane integrity was related to the level of 200 peppermint extracts (P<0.05). 48 hours after sperm storage, the highest total motility, viability and plasma membrane integrity of sperms were belonged to the control group (P<0.05). 72 hours after semen storage, no statistically significant differences were found among treatments for all sperm quality parameters. At this time, the highest concentration of malondialdehyde (MDA) in seminal plasma was related to the level of 100 μl/ml peppermint extract (P<0.05). In general, by adding different levels of peppermint extract to the diluent and maintaining the diluted semen of the Arabi ram in a liquid state at 5°C, the concentrations used of peppermint extract not only did not improve the qualitative parameters of the sperm, it also had a devastating effect.

Abstract X-ray is the one of the types of ionizing electromagnetic rays that is widely used in medical and industrial professions, but also has destructive effects. The present study was conducted to determine the effect of X-ray on count and motility of sperm cells of in adult male rat. 40 male rats were divided into two groups, the treatment group with X-ray with variant radiography and control group, respectively. Then, the total number of sperms and their mobility were analyzed by T-test in both groups. The results showed that X-ray was reduced the total number of sperms significantly. The number of dead and immotile sperms increased in X-treated conditions compared to control group significantly. However, the number of active- progressive and slow motion and non- progressive sperms in the X-ray treated group was not significantly different with the control group. It is concluded that X-ray can have destructive effects on male reproductive systems, including reduction sperm count and motility.
