Cortisol is a destructive "stress" hormone with the opposite effects of anti-aging growth hormone.
Cortisol impacts the actions of testosterone by reducing hormone receptor sensitivity. Cortisol lowers testosterone. It can also play a role in gaining body fat around the belly which further effects your estrogen levels.
Most of the testosterone in your blood is bound to proteins like Sex Hormone-Binding Globulin (SHBG). SHBG has binds to testosterone and effectively reduces free or bio-available testosterone.
In fact, nearly 98% of your testosterone is bound to proteins leaving only 1-2% available or "free". Only free testosterone can connect with androgen receptors and produce the positive effects attributed to testosterone.
Estrogen is a feminizing hormone produced by men as well as women. Too much estrogen in a man can also lower free testosterone.
Testosterone levels should be ten times higher than estrogen levels. But this ratio can get out of balance. High estrogen levels in men can cause feminine features, like manboobs, increased body fat especially belly fat, and reduced libido.
More dangerous than how your body looks because of increased estrogen balance is the impact on heart health and prostate disease.
There are supplements to lower estrogen and How To Reduce Estrogen will show you step by step how to reduce the effects of this hormone.
You have the ability to increase testosterone naturally and safely, restore your testosterone / estrogen balance, and increase your free testosterone without drugs and without side effects.
In your 20s, testosterone is what makes you feel invulnerable.
Over 40, decreased testosterone makes you feel weaker, breakable, and less sure of yourself. (See Natural HGH Releasers - to learn about the impact of another powerful male hormone).
Boost testosterone, reduce estrogen dominance, and support growth hormone production! Mike Mahler Hormone Optimization is the most informative site I've seen offering advice and scientific basis from years of testing and research.
Every man wants to know how to optimize testosterone and with good reason. And while testosterone is critical for men's health and well being, it shouldn't be the focus of the ideal male hormone profile. In fact, testosterone's real attraction is its ability to convert into to a much stronger male androgen - dihydrotestosterone (DHT). Check out MikeMahler.com and get ready for an eye opener.
