So, if what you're saying is true we should eat bull testicles and that will raise are T levels.
It may have an effect, but the effect is not raised T levels in humans that eat meat that contain steroids.
Let me give you an example. If you were to drink a injectable steroid it would not raise your testosterone levels. It would be destroyed during digestion before it ever reaches the blood stream.
Oral steroids have a coating to protect the steroid thru the digestion process so that it is still usable by the time it reaches the blood stream. (Steroid gurus please correct me if necessary)
So, any steroids that are in meat will not have any noticable effect on your T levels. It may have some effects on your health, but that's not the effect I ws referring to in my first post.
As far as doctors telling men with prostate cancer to cut down on red meat, that is due to the high fat content. Many studies have noted an association between high-fat diets and an increased risk of prostate cancer.
As far as the puberty reference, it's possible that a high protein diet, especially one of red meat, increases T levels. But your T levels are not increased due to any steroids in the meat. It may be due to the
extra cholesterol and saturated fat we are consuming in America, which facilitates T production.
