These results suggest that exposure to BPA enhances the RCT process in testicular tissues by up-regulating Apoa1, which in turn inhibits testosterone synthesis and secretion. (A) Detection of mice (A) testicular and (B) serum testosterone levels after BPA treatment. These results indicate that BPA exposure significantly inhibits testosterone synthesis and secretion in mice. This study will provide a new perspective on the mechanism through which BPA inhibits testosterone synthesis in mice by focusing on lipid metabolism. Based on observed evidence from in vitro and in vivo studies, different hypotheses were postulated about the mechanisms through which BPA exerts its toxic effects on reproductive system. This review intends to gather scientific data about the BPA effects on the male reproductive system and the most appropriate analytical strategy. The recognition of effective markers of exposure able to determine and predict the health and reproductive consequences and the identification of therapeutic moieties capable of rescue the BPA-induced toxicity on the male reproductive system represent the major challenges in this field. Overall, available data support an adverse effect of BPA on sperm characteristics, such as reduced motility and concentration, and increased genetic abnormalities; however, these alterations were not accompanied by clear data on fertility outcomes. The protective effect of Selenium (Se) against BPA-induced reproductive toxicity in male mice and rats was also reported 22,143. Recently, Rezaee-Tazangi and colleagues investigated the in vitro effects of taurine (TAU) on BPA-induced OS in testicular mitochondria and on sperm viability and motility . Daily gels, patches, and axillary solutions provide steady levels with easy dose adjustments. Fixing these can improve or even normalize testosterone, and will make any therapy work better. You’re a candidate when you have both consistent low levels and symptoms. If you’re struggling with low energy, a stalled libido, slower recovery in the gym, or brain fog that just won’t lift, you’re not imagining it, low testosterone (low T) is common and treatable. Moreover, exogenous supplement of 22-hydoxycholesterol (22-OH-Chol) were used to uncover the mechanisms by which BPA increases APOA1-mediated RCT led to inhibition of testosterone synthesis in TM3 cells in the presence of BPA. Therefore, investigating the decrease in testosterone synthesis in Leydig cells from the perspective of cholesterol is advantageous. However, few studies have investigated whether BPA regulates testosterone synthesis in mouse testes by enhancing reverse cholesterol transport (RCT). This cholesterol reduction likely led to testosterone synthesis disorders in the model, indicating that BPA inhibits testosterone synthesis in mice by disrupting cholesterol transport. It was observed that serum and testicular testosterone levels were drastically reduced in BPA-treated mice. Regarding maternal BPA exposure and male reproductive function, a weak association of prenatal BPA exposure with sperm quality and testicular functions has been observed in men later in life. BPA affects the human male reproductive system by disrupting the hypothalamic-pituitary-testicular axis and altering the expression and activity of enzymes related to testicular steroidogenesis and spermatogenesis. Interestingly, studies performed in other tissues, such heart, showed that the decrease in GPx, SOD, GST, and CAT activities in BPA exposed groups were not reverted by the administration of TAU or curcumin , which suggest a tissue/cell-dependent response. It was shown that pre-treatment with TAU suppressed BPA-induced mitochondrial OS, enhanced MMP and improved sperm viability and motility in a dose-dependent manner . TAU (2-aminoethanesulfonic acid) is a free amino acid present in several tissues that may act as an antioxidant in sperm.
