Men’s average testosterone levels have halved over the past 50
years, according to scientists who say society is facing a male
fertility crisis. Rising levels of obesity and diabetes are
expected to play a part, but the team behind the work suggest that
environmental factors such as endocrine-disrupting chemicals –
which can be found in various household items – and global heating
could also be factors in the apparent striking decline. Ian Sample
speaks to science correspondent Hannah Devlin to find out how the
work has been received and what the researchers want to see happen
in response to their finding. Help support our independent
