ConservativeMind (From the article):" They found a statistically significant difference in semen volume (down 20% from 2.5 to 2 milliliters),
sperm concentration (down 26.5% from 68 to 50 million per ml of ejaculate),
sperm count (down 37.5% from 160 to 100 million per milliliter of semen),
total motility i.e. being able to move and swim forwards (down 9.1% from 49% to 45%)
and numbers of live sperm (down 5% from 80% to 76%).
"Prof. Núñez-Calonge said motility and the total sperm count were the most severely affected.
Half of the men had total sperm counts that were 57% lower after COVID compared to their pre-COVID samples."
" When the researchers looked at the group of men who provided a sample later than 100 days after COVID, they found that sperm concentration and motility had still not improved over time."

Match this with the documented problems women are having with their reproductive systems, well population control.
I wonder if it gets back to normal eventually. I know vaxes can do reproductive damage for both sexes.
