Our school nurse (over 25 years experience), told me something very interesting that she learned in a training lately. Fertile eggs are lower in cholesterol that unfertile eggs. I don't know how that would make a difference, but she said it was supported in the literature they were given to read during a training concerning obese students and healthy suggestions to give their parents. I don't know if it's true or not, it's just observation on my part that I found interesting and please no flaming or making rude statements this nurse is a lifetime friend of mine.
 
That is interesting. I'd like to see how they came to the conclusion. It really doesn't stand to reason that it would make that big of a difference, but then again, I'm not a scientist. I guess it could be similar to a woman being impregnated. Once there is fertilization hormones change, maybe chicken hormones change because of the fertilization and it changes the PH and other things in the production process of the egg reducing the cholesterol? No idea what cholesterol would have to do with a chicken baby, but it's a half educated guess anyway.

If you find out any more information please share!! That's kind of cool!!
 
I'm pretty sure that is a myth.

According to this http://ucanr.org/freepubs/docs/8154.pdf an egg with "lower" cholesterol wouldn't be able to produce a viable chick, so having an egg become lower-cholesterol just by being fertilized egg wouldn't make much sense.
I also read a study that said higher cholesterol in the egg yolk was correlated to a higher hatch rate.



Research has also shown that the most effective way to lower egg cholesterol content is to lower the energy consumption of the hen. Tampa Farm Services (Florida) markets an egg with reduced cholesterol content (185 mg). The eggs are produced by feeding a special all-vegetarian diet that is higher in protein and fiber, and enriched in vitamin E.

I'd imagine it is the living environment/feed of the hen that produces a lower cholesterol egg, rather than the fertility. Fertile eggs are likely produced by healthier free ranging or cageless hens.
