Trends in Semen Quality: A Contrasting Perspective From a Single‐Centre Review in Ireland
Contrary to concerning reports of a global decline in semen quality, we observed a significant increase in sperm concentration over a 16-year period, with stable rates of oligospermia and azoospermia. These findings emphasise the importance of regional differences and suggest that local factors such as healthcare access and lifestyle may play a role. Examining local trends provides a more nuanced understanding of overall male fertility trends and may inform targeted clinical and public health strategies.
