Effects of BDE47 on testicular morphological, daily sperm production and serum testesterone levels.

<p><b>(a)</b> The testis tissue was stained with hematoxylin and eosin (H&E), and testicular morphological changes and disrupted seminiferous tubule architecture were assessed by optical microscopy. Horizontal arrow, giant cell; vertical arrow, vacuolar spaces in the epithelium. <b>(b)</b> Daily sperm production (DSP) in rats exposed to BDE47. <b>(c)</b> Serum testosterone (T) level in rats exposed to BDE47. Bars show the mean ± SD of 10 animals per group. *<i>P</i><0.05, compared with corresponding BDE47 treatment in saline group; #<i>P</i> <0.05; ##<i>P</i><0.01; compared with corresponding vehicle control.
