Scientists warn that global sperm counts have fallen by more than 60% in the past 50 years, with the rate of decline doubling since 2000. While lifestyle factors play a role, researchers highlight environmental toxins – especially chemicals in plastics – as a central cause. Phthalates, which soften plastics, lower testosterone, while bisphenols, which harden them, mimic estrogen. These endocrine disruptors are especially harmful in pregnancy, where exposure can alter male fetal development and lead to reduced sperm counts in adulthood.
Politics Stalls While Risks Grow
The fertility crisis mirrors the rise of global plastic use since the mid-20th century, yet political progress on regulating harmful additives remains slow. Recent UN talks in Geneva aimed at curbing plastic pollution collapsed after oil- and gas-producing nations opposed limits on chemicals. Experts stress that while individuals can reduce exposure by reusing safe materials and avoiding soft plastics, systemic action is urgently needed. Without stronger regulation and safer alternatives, scientists warn, the decline in fertility will only accelerate, threatening future generations.
