Abstract | The alterations of dopamine D2 receptor (D2R) and ?1 adrenergic receptor (?1AR) expressions and developmentalstages of seminiferous tubule were investigated in twenty-two male rats that underwent one of three Methamphetamine (METH)treatment regimes: acute binge (AB), escalating dose (ED) or escalating binge dose (ED-binge), in comparison with the control.The percentages of stage II seminiferous tubule were significantly decreased in ED and ED-binge groups. Reductions of D2Rimmunoreactivity in spermatocytes were found in all METH treated groups, while D2R reductions in elongated spermatids werefound in ED and ED-binge groups. The expressions of ?1AR in spermatocytes were increased in all METH treated groups aswell as in round and elongated spermatids in ED and ED-binge groups. The results indicate that METH can cause changes inD2R and ?1AR expressions in the testis of METH-addicted rats, which may disrupt DA and NE functions leading to changes ofseminiferous epithelium development and consequently spermatogenesis impairment. |
