let's look at cholesterol itself next, and the different kinds, shall we?

so, if you read this text, you would understand that having this chemical absorb in the intestines directly in its correct form dramatically improves its chances of being available for the liver (via P450) to make it into testosterone

raw egg yolk is one of the best forms of precursor material for synthesising testosterone, and no coincidence that this also is found in the fat of most ruminants, where it is protected from damage much better than in an egg yolk 

 there are few other sources than these two, and you see, the readily absorbable forms simply don't exist in plants and the benefits of it are clear if you are concerned about raising your testosterone levels (and it is equally applicable to estrogen, as they both start with cholesterol)
