Scientists warn that plastic chemicals such as phthalates and bisphenols are playing a major role in the worldwide decline of sperm counts. Research shows sperm counts have fallen nearly 60% since the 1970s, with the rate of decline doubling since 2000. Dr Shanna Swan of Mount Sinai highlights that these endocrine-disrupting chemicals interfere with hormones, particularly during pregnancy, causing developmental changes in boys that can lead to reduced fertility later in life.
Political Inaction Amid Rising Risks
The fertility crisis coincides with the rapid growth of plastic use since the mid-20th century, yet global negotiations to curb harmful additives have stalled. Talks in Geneva collapsed after oil- and gas-producing nations opposed restrictions, leaving chemical regulation off the table. Experts stress that while individuals can reduce exposure by reusing safer containers, systemic action is essential. Without stronger regulations and safer materials, scientists warn that fertility rates will continue to fall, with profound implications for public health and future generations.
