8 Possible Causes of Erectile Dysfunction

Erectile dysfunction, also called impotence, occurs when the penis is not able to achieve an erection when sexually stimulated. 

An erection occurs when the penis receives electric signals being sent from the brain when you are sexually aroused.  As this happens, blood rushes to the penis and remains there in an environment that is very similar to a sponge.

If you suspect that you are at risk of having this disease, it will be helpful for you to know its possible causes.

1. Psychological factors contribute a lot to the incidence of erectile dysfunction. Depression, anxiety, and things that are going on in your mind all contribute to the incidence of impotence. Thoughts that constantly bother you such as problems about money, work, children and relationships, and other nagging thoughts that clutter your mind can interfere with your ability to achieve erection.

2. Neurogenic diseases are types of illness that can cause erectile dysfunction. These diseases originate from the nerves and nerve tissues of the body. If you get sick of this type of disease, your ability to achieve erection is adversely affected as the penis is one body organ that contains nerve endings making it extremely sensitive to changes that affect the nerves and nerve tissues of the body.

3. The medications you are currently taking can be the cause of your impotence. Antidepressants and antianxiety drugs are intended to help keep your mind and body calm and relaxed. The calming and relaxing effect of these medications can adversely affect your response and diminish the excitement that you are supposed to feel when you are sexually stimulated.

4. Old age may contribute to impotence. Old people experience impotence due to several factors that accompany the natural process of aging such as lack of energy, weakness and less interest for sex. However, unlike other similar disorders, erectile dysfunction can affect younger males, too.

5. Diabetes and multiple sclerosis may also cause erectile dysfunction. Diabetes and multiple sclerosis are two debilitating diseases which affect the functions of the nervous system and the body's normal blood flow and can greatly interfere with your ability to achieve erection. Diabetes can affect the normal flow of blood to the penis while multiple sclerosis, which is a disease of the central nervous system can interfere with the transmission of signals from the brain to the penis during sexual stimulation.

6. Smoking may interfere with the body's normal blood flow and cause impotence. This claim may be true only for certain people because not all smokers experience impotence and not all those who experience impotence are smokers. However, smokers who are currently experiencing impotence may benefit from not smoking to allow nicotine-free blood to circulate and flow freely and subsequently help you achieve erection.

7. A major surgery may also contribute to impotence. A person who has just undergone a major operation may experience temporary impotence due to physical weakness, lack of strength and low interest for sex. Who would be aroused amidst post-operation pain and discomfort? However, this lack of interest for sex after operation should only be temporary otherwise, there could be another underlying cause for the impotence.

8. Problems affecting the kidneys can be another cause of erectile dysfunction. A male patient who constantly undergoes dialysis and other procedures related to his illness cannot expect to achieve erection in the midst of discomfort, of taking various medications, and of worrying about his condition, his family and finances.

Green Tea Is Good For You - It Protects You From Cancer

Green tea extract is a very popular beverage considered to contain a greater amount of antioxidants than vitamin C. Green tea has become an overnight sensation because of 4 important qualities that can protect from various diseases and help you pursue a healthy lifestyle.

1. Green tea is an effective antioxidant and has the ability to delay the signs of aging

Green tea protects you from oxidative stress and delays the process of aging by scouring your body's nook and cranny of free radicals and toxic substances that can potentially weaken your immune system making you prone to both bacterial and viral infections. 

Green tea does this function through one of its hardworking components, epigallocatechin gallate which has the ability to protect you from the harmful effects of free radicals and reactive oxygen species.

2. Green tea protects you from cancer

Green tea has the ability to protect you from developing the dreaded cancer by preventing the release of urokinase, the enzyme that is responsible for contaminating healthy cells, promoting metastasis, and for spreading cancer cells. The absence of urokinase prevents tumors from increasing in size and can in fact remove the tumor completely.

3. Green tea relieves the symptoms of inflammation

Green tea protects your body from inflammation by decreasing fat peroxidization, and nitric acid production. More specifically, the epigallocatechin gallate (EGCG) content of green tea can inhibit the production of mediators and cytokines (substances that cause inflammation). EGCG also has the ability to significantly decrease production of the harmful substance peroxynitrite which is a component of reactive oxidative species, as well as decrease nitric oxide content by minimizing the activities of NF-kB and AP1.

4. Green tea protects you from radiation

Green tea extract protects you from the harmful effects of radiation when exposed to the sun by decreasing the amount of reactive oxidative species (ROS) that is released by the ultra violet A rays. It also inhibits apoptosis or sudden cell death, and has the ability to prevent certain abnormalities and irreversible damage to your body's DNA caused by the harmful UVA rays.
