Prochloraz induced alterations in the expression of mRNA in the reproductive system of male offspring mice.

Prochloraz is a widely used fungicide worldwide. It is classified as an endocrine disrupting pesticide that affects the reproductive system. This study aimed to examine the impact of exposure to prochloraz of male mice on the reproductive system of their offspring male mice. Male father mice were intragastrically administered different dosages of prochloraz (group MA: 0 mg/kg/day; MB: 53.33 mg/kg/day; MD:160 mg/kg/day). Then, the testicular average weight of male offspring in the dose groups was found to be significantly lower than those in the control group (MB:0.312g, MD:0.294g, and MA:0.355 g; P  < 0.05). Additionally, the testicular coefficient index in the MB and MD groups was also lower than that of the control group. Secondly,we observed that there were significantly different expressed genes clustered in groups B and D, in contrast to the control. Finally, the findings demonstrated a significant alteration in the response of male mice reproductive relative genes to prochloraz invasion. Two genes ( Mt-nd6 and Slc12a4 ) were found to be involved in the regulation of sperm mitochondria function and six genes ( Greb1, Esrrb, Catsperb, Mospd2, Sohlh1 and Specc1 ) were closely linked to sperm functions and estrogen response. The study revealed a significant impact of prochloraz on the reproductive system of male mice, thereby supporting further investigation into the reproductive toxicological effects of the drug.
