ABSTRACT
Highly effective antimicrobial properties of triclosan (TCS) make its use as a widely used preservative in different types of consumer products. TCS is reported as an emerging endocrine disruptor causing reproductive impairments in the males as well as in the females. The present study describes the adverse effects of various doses of TCS (40, 80, 160 and 320 mg/kg B W/day, for 42 consecutive days) on the weights and histopathology of the epididymis and seminal vesicle, sperm indices (motility, viability, count and morphology), concentrations of epididymal sialic acid and seminal vesicular fructose, along with TCS accumulated in these accessory reproductive organs of the laboratory mouse. TCS induced significant reductions in the weights of the epididymis and seminal vesicle along with noticeable histopathological alterations in these organs. TCS caused significant reductions in the count, percentage of motile and viable spermatozoa while a significant increase in the percentage of abnormal spermatozoa in the epididymis. Concentrations of epididymal sialic acid and seminal vesicular fructose declined significantly in the treated mice. A significant increase was noticed in the concentration of TCS, accumulated in the epididymis and seminal vesicle following TCS exposure at a high dose (320 mg/kg BW/day). The results thus suggest that the accessor y sex organs are also affected deleteriously following TCS exposure, leading to impairment in the male reproductive health.
