Morphofunctional characteristics of testes in white rats treated with bisphenol a and triclosan

We studied the effect of unstable ubiquitous endocrine disrupters bisphenol A (BPA) and triclosan (TCS) on the reproductive function of adult male Wistar rats. BPA and TCS concentrations were measured directly in testicular tissue by gas chromatography with mass spectrometry (GC-MS). Comparison groups were found to be statistically significantly different in the concentrations of bisphenol A and triclosan in testicular tissues. The study showed that bisphenol A and triclosan have a negative effect on the morphofunctional state of the male reproductive glands of sexually mature rats, causing a decrease in testicular mass, a decrease in parenchyma, the number and diameter of the seminiferous tubules, an increase in the number of convoluted seminiferous tubules with desquamated epithelium, and a decrease in sperm cells on the background of an increase in their atypical forms.
