Pick a day — any day — and there is sure to be a lot of human semen entering the world from private parts unknown. What it gets up to — when it gets out there — is anyone's guess.
Each day there's buckets of the stuff discharging forth half a teaspoon at a time. If we were to check the manifest, despite the current trend for low numbers, 200-300 million spermatozoa are on board bravely going where no wriggly thing has gone before. Just imagine how many sperm are sent on a mission each Saturday night! What with one thing and another, most of them are going to be dead by breakfast.
Such is life ... for sperm.
Lest we forget them.
If it wasn't for those few who make it, where would the patriarchy be today. For millennia we just thought milking males for semen was a fun thing to do. We didn't know it could help make babies. And now that we do, every sperm is suddenly so very sacred — so sacred that we are encouraged not to spill a single drop.
