News | Does Environmental BPA Threaten Male Fertility? Evidence Remains Mixed
A review published in the International Journal of Molecular Sciences examined the effects of bisphenol A (BPA) on male fertility. BPA is a common endocrine-disrupting chemical widely used in plastic production. Although concern about its health risks is growing, its specific effects on the male reproductive system require further study.
Effects of BPA on the male reproductive system
BPA can disrupt hormonal balance by mimicking estrogen, particularly through effects on the hypothalamic-pituitary-testicular axis and changes in the expression and activity of enzymes involved in testicular steroidogenesis and spermatogenesis. It may also suppress antioxidant defenses and cause oxidative stress, damaging sperm, reducing sperm quality, and potentially contributing to infertility.
Occupational exposure and fertility
Some studies show that men with long-term, high-level occupational BPA exposure have significantly lower androgen, testosterone, and follicle-stimulating hormone (FSH) levels, along with higher sex hormone-binding globulin, estradiol, and prolactin levels. These hormonal changes may contribute to male infertility.
Environmental exposure
The effects of low-level environmental BPA exposure on male fertility remain unclear. Some studies have reported adverse effects on sperm motility, Leydig cell function, and sperm count, but findings are inconsistent.
Conclusion
Most current research associates high-level BPA exposure with poorer sperm quality and reduced male fertility. However, there is no conclusive evidence about the effects of low-level environmental exposure. More research is needed on the chemical's long-term effects on human fertility.
