Erectile Dysfunction
What is Erectile Dysfunction?
Erectile dysfunction, often called ED, is the inability to get or maintain an erection firm enough for sexual activity. It affects over 30 million men in the United States. This condition is not just about age. It can happen to men at any stage of life.
ED is often a sign that something else is going on in your body. Hormonal imbalances, blood flow issues, and metabolic problems can all cause erectile dysfunction. Your body uses hormones like testosterone to regulate sexual function. When testosterone levels drop or prolactin levels rise too high, erections become difficult or impossible.
Many men feel embarrassed to talk about ED. But this condition is treatable, and understanding the root cause is the first step. Blood tests can reveal hormone imbalances that contribute to erectile dysfunction. Addressing these imbalances can restore function and improve quality of life.
Symptoms
- Difficulty getting an erection
- Trouble maintaining an erection during sexual activity
- Reduced sexual desire or low libido
- Erections that are not firm enough for penetration
- Inability to achieve orgasm despite stimulation
- Morning erections that disappear or become less frequent
- Anxiety or stress related to sexual performance
Some men experience occasional erectile difficulties, which is normal. Erectile dysfunction is diagnosed when symptoms persist for several weeks or months. Early stages may involve intermittent problems that gradually become more frequent.

Causes and risk factors
Erectile dysfunction has many potential causes. Hormonal imbalances are a major factor. Low testosterone levels reduce sexual desire and make erections difficult. High prolactin levels suppress testosterone production and directly interfere with sexual function. Other hormonal issues like thyroid problems can also contribute. Physical causes include poor blood flow, nerve damage, diabetes, high blood pressure, and obesity. Medications for depression, anxiety, and blood pressure can cause ED as a side effect.
Lifestyle factors play a significant role. Smoking damages blood vessels and restricts blood flow to the penis. Excessive alcohol use impairs nerve function and hormone production. Lack of exercise, poor diet, and chronic stress all increase ED risk. Psychological factors like anxiety, depression, and relationship stress can worsen or trigger erectile dysfunction. Sleep disorders and sleep deprivation also affect hormone levels and sexual function.
How it's diagnosed
Diagnosing erectile dysfunction starts with a conversation about your symptoms and medical history. Your doctor will ask about medications, lifestyle habits, and any other health conditions. A physical exam checks for signs of hormonal or circulatory problems. Blood tests are essential for finding the root cause. Testing for total testosterone, free testosterone, and prolactin reveals hormone imbalances that commonly cause ED.
Rite Aid offers testing for testosterone and prolactin levels through our preventive health service. You can get tested at over 2,000 Quest Diagnostics locations nationwide. These blood tests help identify hormonal causes of erectile dysfunction so you can address the underlying problem. Additional tests may check blood sugar, cholesterol, and thyroid function to rule out other contributing factors.
Treatment options
- Lifestyle changes including regular exercise, especially cardio and strength training
- Weight loss if overweight, as excess body fat lowers testosterone
- Quit smoking to improve blood flow and vascular health
- Limit alcohol to no more than 1 to 2 drinks per day
- Stress reduction through meditation, therapy, or relaxation techniques
- Improve sleep quality by maintaining consistent sleep schedules
- Nutrition changes focusing on whole foods, healthy fats, and adequate protein
- Testosterone replacement therapy if levels are clinically low
- Medications to lower prolactin if levels are elevated
- Oral medications like sildenafil or tadalafil to improve blood flow
- Counseling or sex therapy for psychological factors
- Treatment of underlying conditions like diabetes or high blood pressure

Frequently asked questions
Erectile dysfunction has multiple causes, but hormonal imbalances are very common. Low testosterone levels reduce sexual desire and make achieving erections difficult. High prolactin levels suppress testosterone and directly interfere with sexual function. Other causes include poor blood flow, nerve damage, diabetes, medications, and psychological stress.
Yes, low testosterone is a major cause of erectile dysfunction. Testosterone plays a key role in sexual desire and the physical process of achieving erections. When total or free testosterone levels drop below normal, men often experience reduced libido and difficulty maintaining erections. Blood testing can identify low testosterone so it can be treated.
Blood tests for erectile dysfunction measure hormone levels that affect sexual function. Total testosterone and free testosterone tests reveal if your levels are low. Prolactin testing checks for elevated levels that suppress testosterone and cause ED. These tests help identify the hormonal root causes of erectile dysfunction.
Erectile dysfunction is usually not permanent and can often be reversed. If caused by hormonal imbalances, lifestyle factors, or medications, treatment can restore function. Addressing low testosterone, reducing stress, losing weight, and improving cardiovascular health often lead to significant improvement. Early intervention produces the best outcomes.
Erectile dysfunction can occur at any age but becomes more common after age 40. About 40% of men experience some ED by age 40, and prevalence increases with age. However, many younger men also experience ED due to stress, lifestyle factors, or hormonal issues. Age alone does not cause ED.
High prolactin levels, called hyperprolactinemia, cause erectile dysfunction in two ways. First, elevated prolactin suppresses testosterone production, leading to low testosterone levels. Second, high prolactin directly interferes with sexual function and desire. Prolactin testing is recommended when ED occurs alongside decreased libido.
Many cases of erectile dysfunction improve with natural lifestyle changes. Regular exercise, weight loss, better sleep, stress reduction, and quitting smoking all help restore function. Improving diet with nutrient-dense foods supports hormone production. However, if blood tests reveal hormonal imbalances, medical treatment may be needed alongside lifestyle changes.
The timeline for reversing erectile dysfunction depends on the cause. Lifestyle changes may show results in 6 to 12 weeks. If hormone replacement therapy is needed, improvements often begin within 4 to 6 weeks. Some men notice changes sooner, while complex cases may take several months.
Erectile dysfunction does not always mean low testosterone, but low testosterone is a common cause. Other factors like high prolactin, poor circulation, diabetes, medications, and psychological stress also cause ED. Blood testing for testosterone and prolactin helps determine if hormones are contributing to your symptoms.
Yes, testing is recommended if you experience persistent erectile dysfunction. Blood tests for testosterone and prolactin identify hormonal imbalances that may be causing your symptoms. Finding the root cause allows for targeted treatment rather than just masking symptoms. Early testing leads to better outcomes and can reveal other health issues.
