Erectile dysfunction occurs when a man struggles to achieve or maintain an erection firm enough for sexual activity. It is a common condition that can affect men of all ages but becomes more prevalent with age. The causes of ED can be both physical and psychological. Physical factors include heart disease, high blood pressure, diabetes, obesity, hormonal imbalances, and side effects of certain medications. These conditions reduce blood flow or interfere with nerve signals to the penis. Lifestyle habits like smoking, excessive alcohol consumption, and lack of exercise also increase the risk. On the psychological side, stress, anxiety, depression, and relationship problems can significantly impact sexual performance. Often, ED results from a combination of both mental and physical factors.

Testosterone, the primary male sex hormone, plays a key role in sexual desire and erectile function. Low testosterone (low T) levels can contribute to ED, particularly if accompanied by fatigue, reduced libido, and mood changes. However, not all cases of ED are due to low testosterone. Blood tests can determine hormone levels, and if low T is diagnosed, testosterone replacement therapy (TRT) may be an option. It’s important to work with a doctor to evaluate if TRT is safe and beneficial in your case.
