Tiny plastic particles, no wider than a human hair, have made their way into an alarming new corner of human biology: the fluids surrounding eggs in women and sperm in men. The latest research, unveiled at the 2025 European Society of Human Reproduction and Embryology conference and published in the journal Human Reproduction, provides the clearest evidence yet of microplastics’ persistent ability to infiltrate the most sensitive aspects of our bodies—raising serious questions about fertility, long-term health, and the true cost of our reliance on plastics (Earth.com; CNN).

A European study presented at the European Society of Human Reproduction and Embryology conference and published in Human Reproduction reports microplastics in fluids around eggs and sperm. The findings raise urgent questions about fertility, long-term health, and the hidden costs of plastic dependence. For Thai audiences, the implications are especially relevant given rapid urban growth, Western-style diets, and widespread use of plastic containers.

Researchers analyzed follicular fluid from 29 women and semen from 22 men. Microplastics appeared in 69% of the women’s samples and 55% of the men’s samples. Detected materials included PTFE, polypropylene, polystyrene, and PET—items once common in nonstick cookware, packaging, and synthetic textiles. The study highlights how pervasive microplastics can be inside the human body.

A landmark international study has revealed that phthalates—a class of chemicals widely used in common household plastics—may be responsible for more than 350,000 deaths from heart disease around the world in a single year. The research specifically identifies di(2-ethylhexyl)phthalate (DEHP), a primary plasticizer in consumer products ranging from food packaging to personal care items, as a significant contributor to cardiovascular mortality, marking an urgent public health concern for both global and Thai communities (CNN, Washington Post, NYU Langone).

A large international study links a common plastic additive, DEHP, to hundreds of thousands of heart disease deaths worldwide in a single year. The research identifies DEHP, a primary plasticizer used to make plastics flexible, as a significant contributor to cardiovascular death. This finding is particularly relevant for Thailand, where plastic use is high in everyday life.

In Thailand, people regularly encounter phthalates through food packaging, cosmetics, cleaning products, and children’s toys. With heart disease already a leading health concern in the country, understanding environmental risk factors is crucial for families and health officials alike. Thailand’s health data show heart disease remains a major cause of mortality, underscoring the need to scrutinize exposure sources and protective measures.

A new line of research draws a surprising link between the reproductive health of seals and human fertility. Scientists are studying seals, distant from clinics, to understand why fertility may be declining across species. Research highlights the role of environmental pollutants and the hormones they disrupt, which can affect reproduction in wildlife and humans alike.

For Thailand, where birth rates are falling and families face growing demographic pressures, these findings offer a global context for local policy and health strategies. Understanding how chemicals in the environment influence fertility can guide practical actions at home, in communities, and in government programs.

Recent research is drawing unexpected parallels between the reproductive lives of seals and the challenges facing human fertility, sparking fresh conversations about the hidden environmental factors impacting reproductive health worldwide. As reported in a feature by Oceanographic Magazine, scientists are turning their attention to seals — charismatic marine mammals that live far from hospitals and clinics — in hopes of unraveling why fertility rates are declining across species, including humans (Oceanographic Magazine).
