When sperm crosses borders, national safeguards fall short
The researchers found that important measurements such as semen volume, total sperm count, sperm concentration and sperm motility remained relatively constant over the years.
In 2021, 41% of men had at least one sperm count below the World Health Organisation standard. In the earlier study group, the figure was 62%.
However, according to the researchers, this seemingly positive trend could also be explained by a bias in the selection of participants.
