which is to simply do a sperm analysis. Refrain from ejaculation for 48 to 72 hours. Give a sperm sample. Have that sperm sample analyzed.
if we're doing a seen analysis now we're trying to evaluate the sperm and any test has certain normal parameters and these are all based on a 48 to 72h hour abstinence period
we asked them to produce a specimen — with no prior ejaculation for 72 hours because you can actually deplete sperm counts — if couples are having intercourse every day
