What makes a man be a real man? The answers may be different: behavior, male-built body, mustaches and beard, etc. But if thinking about the topic deeper, it is testosterone that defines the following male identities:

– Muscle bulk;
– Stress resistance;
– Physical endurance;
– Sexual activity;
– Weight;
– Lack of tearfulness;
– Overall energy production;
– Anatomical signs.

Testosterone is very unstable and is able to mutate into female hormone estrogen. Food can be very harmful for testosterone especially products oxidizing blood and product containing estrogen and phytoestrogen. Of course, there are products that enhance testosterone level like some medications like US Viagra but it’s needed to keep up with products violating testosterone:

1. Salt. Reduces testosterone production.
2. Sugar. Instigates insulin production that suppresses testosterone production.
3. Caffeine. Destroys male hormone. But it works for a short period of time and deteriorates quickly.
4. Meat. It’s a known fact that cattle get female hormones for muscle bulk increase. Also, fat meat contains much cholesterol that is very harmful for testosterone. But if cholesterol takes part in testosterone production but the toxicity of cholesterol destroys testosterone.
5. Soy. Contains phytoestrogen.
6. Fat milk. Contains natural cow estrogen.
7. White salt-rising bread and baking. They contain several harmful factors: sugar, acids and yeast.
8. The abundance of vegetable oil. The most harmful oils for testosterone are soya oil, corn oil and linseed oil. Sunflower oil is less harmful but olive oil and nut oil are even healthy.
9. Eggs. Contain many different hormones and cholesterol.
10. Smoke products. Contain smoking fluid that is toxic for testicles.
11. Alcohol. Testosterone level lowers by 20% for 12-20 hours after drinking much alcohol. The most harmful is beer because it contains phytoestrogen.

Unfortunately all these products are included into a daily male diet that’s why it’s possible to speak about regular harmful influence on male testosterone level and metabolic disease.
Scientific findings show that ongoing taking of US Viagra enhances blood flow. Also US Viagra increases testosterone level. However, scientists say that US Viagra online doesn’t directly affect on testosterone level. It’s a well-known fact that taking US Viagra online increases the frequency of successful sexual intercourses that enhance testosterone level in turn. Thus taking US Viagra and having frequent sex transactions lead to the increase of testosterone level by nearly 50%. Also, some researches show that ongoing taking US Viagra enhances working capacity, muscle growth and metabolism. If you choose to buy Viagra online do it only after specialized medical consultation because it has got some side effects and contraindications.
