Men’s average testosterone levels have halved over the past 50 years, according to scientists who say society is facing a male fertility crisis. The decline has been linked to rising levels of obesity and diabetes, but the research team suggests that environmental factors such as endocrine-disrupting chemicals found in household items and global heating could also play a role.
Details of the Study
Speaking to science correspondent Hannah Devlin, Ian Sample explored how the work has been received and what researchers want to see happen in response. The scientists behind the study emphasize that the decline is striking and warrants urgent attention.
Impact and Implications
The findings highlight a potential public health crisis, with implications for male reproductive health and overall well-being. The researchers call for further investigation into the role of environmental toxins and climate change in driving this trend.
