Scientists Find Pollution Hurting Men's Ability to Have Children

June 5, 2026 · BBC

New research shows chemicals in our environment may be causing sperm problems that make it harder for couples to have babies.

Scientists are worried about a growing problem with men's health around the world. Research shows that pollution and chemicals are making it harder for men to have children. This affects millions of couples who want to start families. The problem has been getting worse over the past 50 years.

Sperm are very special cells that help create babies. They must be able to swim well and have the right shape to work properly. Scientists have found that sperm counts are dropping in many countries. The number of healthy sperm in men has fallen by more than half since 1973.

Chemicals in our environment are hurting men's fertility. These harmful substances are found in plastic containers, household items, and even the air we breathe. Hot weather from climate change also damages sperm. Poor diet, stress, and alcohol make these problems worse.

Many men feel embarrassed when they learn about fertility problems. They often suffer alone without getting help or talking to others. This can lead to sadness, worry, and other mental health issues. Doctors say it is important for men to get support and treatment.

There are ways men can protect their health and improve their chances of having children. Eating healthy foods and exercising regularly can help sperm quality. Avoiding plastic containers with harmful chemicals is also important. However, solving this problem will require cleaning up pollution in our environment too.

We are facing a public health crisis - and we don't know if it's reversible.
