Scientists warn that plastic additives such as phthalates and bisphenols are contributing significantly to a global decline in sperm counts. Research led by Dr Shanna Swan shows sperm counts have dropped nearly 60% since the 1970s, with the rate of decline accelerating to more than 2% per year since 2000. These chemicals, found in everyday items from food packaging to medical tubing, disrupt hormones by lowering testosterone or mimicking estrogen. Exposure during pregnancy is especially harmful, leading to developmental issues in male fetuses and reduced fertility in adulthood.
Political Deadlock Hampers Action
The fertility crisis coincides with the explosion of global plastic production since the mid-20th century, yet efforts to regulate harmful chemicals face resistance. Recent negotiations in Geneva to draft a global plastic treaty collapsed after oil- and gas-producing nations blocked proposals to limit production and chemical use. While individuals can reduce exposure by choosing safer materials, experts stress that systemic regulation and innovation in safer alternatives are urgently needed. Without action, scientists warn, reproductive health will continue to deteriorate worldwide.
