Scientists are raising alarms over a global decline in sperm counts, warning that plastic additives such as phthalates and bisphenols are key contributors. Research shows sperm counts have fallen by about 1% per year for 50 years, with recent studies indicating the decline is accelerating to more than 2% annually. This trend, observed worldwide, aligns with the rapid rise of plastic production since the mid-20th century.
Hormone Disruption and Health Risks
Phthalates, which soften plastics, lower testosterone, while bisphenols, which harden plastics, mimic estrogen. These endocrine-disrupting chemicals are particularly harmful to developing fetuses, leading to altered sexual development and reduced fertility in adulthood. Researchers argue that these exposures are a major factor in the ongoing fertility crisis.
Political Deadlock on Plastic Treaty
Despite growing evidence, global negotiations in Geneva to limit plastic production and regulate harmful additives collapsed, with oil- and gas-producing nations blocking stricter controls. Experts stress that while individuals can reduce exposure by using alternatives like glass or stainless steel, systemic solutions and stronger regulations are urgently needed to protect human health and future generations.
