What causes an erection?
An erection occurs because of sensory or mental stimulation, or both, that results in blood flowing into the penis making the penis expand. Once the blood flows into the penis, muscles in the penis contract to stop the inflow of blood, which causes an erection. When muscles in the penis stop contracting outflow channels are opened that reverse the erection. Why can't I get it up? What causes erectile dysfunction.
There is a large silence around erectile dysfunction, as an erection is commonly associated with potency, success and masculinity. Yet many men may experience erectile dysfunction in their lifetime. In fact, most men do at some point in their lives. Erectile Dysfunction, or ED, occurs when you can't keep an erection, may keep an erection sometimes and other times not, or are only able to keep an erection for a brief period. It can be caused by a medical problem, such as diabetes, heart and vascular (blood vessel) disease, kidney or liver failure. It can also be caused by hormonal imbalances, alcoholism, drug abuse or the side effects of certain medications. Psychological causes of erectile dysfunction can be depression and performance anxiety (worried about your ability to perform sexually), feeling nervous about sex (perhaps because of a previous bad sexual experience ), feeling stressed (including stress from work or family situations), or being troubled by problems in your relationship. If a Brother is experiencing erectile dysfunction he should visit his doctor as soon as possible, to make sure there is no medical issue such as a heart problem. Thankfully, erectile dysfunction can be treated.
