Do you have a source for the claim that sperm count for many mammals has been declining? I was only able to find "Sperm counts in semen of farm animals 1932-19

Do you have a source for the claim that sperm count for many mammals has been declining?
I was only able to find "Sperm counts in semen of farm animals 1932-1995" https://pubmed.ncbi.nlm.nih.gov/9401823/ https://pubmed.ncbi.nlm.nih.gov/9401823/
Which states that farm animal sperm count has unchanged or has increased over time.
