Does not fully answer your question - and I have no idea of the reliability of this information which I found here: http://www.goaskalice.columbia.edu/1585.html

"A typical ejaculation fills up about one teaspoon; the actual amount is determined by a man's age (younger men usually make more semen), when he last ejaculated, and how long he's aroused before ejaculating, among other factors. Contrary to what you've heard, semen is not loaded with calories. Each teaspoon of ejaculate has about 5 - 7 calories and some 200 - 500 million sperm. Since sperm make up only about 1 percent of semen, what accounts for the other 99 percent? Well, its other ingredients include:


Fructose sugar
Water
Ascorbic acid (a.k.a., vitamin C)
Citric acid
Enzymes
Protein
Phosphate and bicarbonate buffers (bases)
Zinc

Can swallowing semen enrich a poor diet? Unless you're gulping gallons of it each day, it's no substitute for real nutritious cuisine."

Think you are going to be a very busy gentleman if you are going to try and feed a basement full of ladies.
