I would be interested in reading that if you find it. My experience was that DH had normal counts but we were in fertility treatment for me...every day the counts were markedly lower...every 2-3 days was ideal. More than that, motility was down. We were using a gender selection technique so sperm maximization weas very important - they gave us very certain cutoffs, and would sometimes alter the suggestion based on the counts, but I never heard of them suggesting every day.
When I conceived naturally I did every other day around O time, and the day of O. So on day it might be two days in a row, but not generally.
