The Guardian has a recent article about the science behind falling sperm counts, and the lack of agreement among medical professionals about whether or not this constitutes a crisis.
Claims from some US scientists that average testosterone levels have halved in the past 50 years have caught the attention of policymakers such as Robert F Kennedy Jr, the US secretary of health and human services, who called it an 'existential crisis'. However, other studies have not replicated the findings.
The article features a range of experts, who discuss the possible effects of pollution, microplastics and overall metabolic health on male fertility, as well as future treatments in the field.
BBC News also has an article about young men trying to boost their sperm counts even though they are not currently trying to conceive or planning to start a family soon. The article looks at the influence of social media on anxiety in men who have never been diagnosed with fertility problems.
