Out DNA fragmentation in spermatozoa respectively (Figure C).Ethical consideration All protocols were performed in line with the national institute of wellness guide for the care and use of laboratory animals (NIH Publications No revised).The applied protocols and animals’ ethics were authorized by the study council of ethical committee of Yazd investigation and clinical center for infertility and Islamic Azad University of Ashkhezar, Yazd, Iran.Statistical analysis For statistical evaluation, we made use of Statistical Package for the Social Sciences, version SPSS Inc, Chicago, Illinois, USA(SPSS).ANOVA and KruskallWallis tests have been utilised for comparison from the data in between distinct groups.The data have expressed as median (minmax) and the differences were statistically important at p.ResultsSperm parameters According to table I, while, the sperm count showed a decreasing trend in medium and high dosage groups when in comparison to low dosage and manage 1, nevertheless it was not statistically significant.Injection of MA decreased the price of progressive motility in medium and higher dosage groups but not in low dosage group (p.and p respectively; Table I).Also, nonprogressive motility and immotile spermatozoa were considerably improved in medium and high dosage groups in comparison with control and low dosage groups (p Table I).Typical morphology was drastically decreased in medium and high dosage groups in comparison to other groups.Sperm chromatin and apoptosis evaluations There was a significant raise in rate of AB and TB spermatozoa in higher dosage group in comparison with other folks.TA-02 Autophagy Furthermore, the rate of CMA sperm cells in medium and high dosage groups showed a significant increase when compared with handle group.In similar case, a substantial difference was observed amongst higher dosage group and others in AO, TUNEL and SCD (p p.and p.respectively) (Table II).Table I.Effect of distinctive doses of MA on sperm parameters and AR in miceGroups Sperm parameters Count (ml) Progressive motility Nonprogressive motility Immotile sperm Standard morphology AR Information are shown as median (min max).MA Methamphetamine Handle Low dosage .
