We monitored the effects of subchronic exposure to furan on the male reproductive system.
Serum testosterone levels were increased serum LH was decreased.
There were no changes in 17-OHase, 3尾-HSD and 17尾-HSD activities or serum FSH.
The mRNA level for StAR was increased by all doses of furan.
The mRNA for Cyp11a1 and intratesticular testosterone were increased by furan.
We conclude that subchronic furan exposure affects testicular steroidogenesis.
