Explain the difference between sperm (the mass noun or singulare tantum which refers to a substance, not the count noun which refers to a spermatozoon) and semen. I want a clear, definitive explanation with sources and references, if possible, because Wikipedia does not explain the difference accurately. 2004-12-29T22:45Z 19:04, August 27, 2005 (UTC)

Since no one wants to or is able to explain, I'm gonna write a disambiguation page, because the two homonymous words sperm (singulare tantum) and sperm (count noun) don't refer to the same concept, and since many articles which direct here refer to the mass noun instead of the count noun. 2004-12-29T22:45Z 19:14, August 27, 2005 (UTC)
