Erectile Dysfunction Symptoms, Causes and Options: A Guide

If you’re asking how erectile dysfunction is treated, the short answer is that most men start with a prescription pill such as Viagra, Cialis or Levitra, after a check for what is causing it. We walk through the symptoms, causes, dose and timing, side effects, interactions with medications, and what the seller says about Red Horse Gummies below.

Erectile dysfunction (ED) is common. Harvard Health says about half of men ages 40 to 70 have ED to some degree, and the medical options range from prescription pills to injections, vacuum devices, counseling and, less often, a penile implant. Red Horse Gummies is a supplement sold to men for vitality and stamina, and the seller’s claims are covered further down.

What are the symptoms of erectile dysfunction?

The NIDDK symptoms and causes page lists three patterns: getting an erection sometimes but not every time you want sex, getting an erection that does not last long enough for sex, and being unable to get an erection at any time. Harvard Health adds that ED can come on suddenly or gradually, that some men slowly lose firmness, and that some men keep normal orgasm and ejaculation without a full erection.

What is the main cause of erectile dysfunction?

Harvard Health says vascular (blood vessel) disease is the most common medical cause, because an erection depends on blood filling the penis. Nerve damage from diabetes, multiple sclerosis, prostate surgery or spinal cord injury is another major cause. The NIDDK also lists heart and blood vessel disease, high blood pressure, low testosterone, thyroid imbalance, enlarged prostate and certain medicines, including some blood pressure medicines and antidepressants. Anxiety, depression, stress and low self-esteem can also cause ED or make it worse, and inactivity, heavy drinking, smoking and recreational drugs can contribute. The AMA’s guide to what doctors want patients to know about ED describes the condition as multifactorial. You can also read our page on prostate and men’s sexual health for how prostate issues fit in.

Is erectile dysfunction normal at 30, 40 or 65?

Erectile dysfunction is common, and it increases with age. The AMA’s urologist, Amanda Swanton, says onset may start in the 40s and 50s, and she puts the figure at about 40% of men in their 40s, rising by about 10% for each decade. She says the majority of men after 50 have some degree of ED. The AMA says onset may be earlier for some men than the 40s and 50s. Urology Specialists, a urology practice, says around 52 percent of all men experience some form of ED during their lives. At 65, the AMA notes that the risk comes largely from conditions that rise with age, such as heart disease, diabetes and obesity. Harvard Health says ED can be addressed in all age groups.

Why am I only getting semi-hard?

An erection that is firm sometimes but not firm enough for sex is one of the patterns the NIDDK lists as a symptom of ED. The causes can be vascular, nerve-related, hormonal, a side effect of a medicine, or emotional, and an exam and history are how a doctor sorts them out. Harvard Health says ED is often an early warning sign of underlying cardiovascular disease, so it is worth raising. Harvard’s overview also says to speak to your doctor if you have trouble getting or keeping an erection for three months or more.

Can ED go away on its own?

Sometimes. Harvard Health says ED caused mainly by psychological factors may get better on its own and can improve at any time. When a physical factor is the cause, treatment is needed. Harvard also says the outlook for most men with ED is positive. Because you cannot tell which kind you have from the symptoms alone, ask a doctor if the problem lasts.

What are the treatment options for erectile dysfunction?

Harvard Health says the usual first step is an oral medicine, and its A-to-Z guide on erectile dysfunction describes several other options if those do not suit you.

How quickly do ED pills work, and how long do they last?

Harvard Health says the onset of ED pills ranges from 15 to 60 minutes. Neither Viagra nor Levitra works well if taken after a meal, while Cialis and Stendra are not affected in the same way. Here is how the three drugs compare on Harvard Health’s figures:

Harvard Health notes that Cialis taken daily works differently from a single dose. Its guidance also says the drugs do not work well without sexual stimulation, so they are not an on-off switch.

How quickly can ED pills work?

The quickest medical option described here is a prescription PDE5 pill, which Harvard Health says can start working within 15 to 60 minutes. Harvard warns that these drugs work best with sexual stimulation and a partner, not as a stand-alone fix. For a fast answer, talk to a doctor about which drug suits your heart and blood pressure medicines, and see our guide to hims for erectile dysfunction if you are comparing prescription routes.

Viagra: what it does and what to know

Harvard Health says sildenafil (Viagra) is often the first drug a doctor offers, because it has been on the market longest and its side effects and interactions are well known. Harvard also says ED drugs work for about 70% of men, but results vary, and men with nerve or artery damage from prostate surgery, diabetes or cardiovascular disease may respond less strongly. Harvard says the most common side effects are headache, flushing, upset stomach, nasal congestion, vision problems, diarrhea, dizziness and rash.

Harvard Health says PDE5 drugs must not be taken with nitroglycerin or other nitrates because of dangerous low blood pressure. It also says an erection lasting four hours or more needs hospital care, and that sudden vision or hearing loss needs immediate medical attention. Harvard advises taking alpha blockers, a common urinary medicine, at least four hours apart from ED drugs.

Harvard Health also says the main obstacle for many men is cost, because insurers often limit the number of pills per month. It names GoodRx as one price-comparison tool and suggests asking your doctor about manufacturer discount programs. The AMA’s urologist says Viagra and Cialis tend to be cheaper than the other oral options.

My husband takes Viagra and doesn’t tell me. What should I do?

Start with a conversation rather than a confrontation. The AMA’s urology guide says ED can leave a partner feeling hurt or feeling there is a lack of attraction, when the real issue is an underlying disease. It also says understanding that a disease is present, and being able to talk about it, matters. Partners can come to appointments so they hear the same information, or go to a sex therapist together or separately. If you are worried about his other medicines, ask him to check with his prescriber or pharmacist, because Harvard Health says none of the ED drugs is safe to take with nitrates.

What lifestyle changes can help with erectile dysfunction?

The clearest guidance is about protecting blood vessels. The NIDDK lists not getting enough physical activity, drinking too much alcohol, smoking and recreational drugs as lifestyle behaviors that can contribute to ED. Harvard Health advises a healthy diet, daily exercise, not smoking, and keeping blood pressure and cholesterol in a normal range. Urology Specialists says men with obesity have a 40 percent higher risk of ED, and it recommends reducing stress, cutting back on alcohol and quitting smoking. Harvard Health says there is not yet strong proof that a healthier lifestyle fixes erection problems, but that it can’t hurt.

What type of exercise helps with erectile dysfunction?

Two kinds come up. Pelvic floor (Kegel) exercises are the one Urology Specialists describes. Its article says research showed 40 percent of men regained normal erectile function, and a further 35.5 percent saw an improvement, so treat those as the practice’s figures. The AMA’s urologist says exercise promotes cardiovascular health, which decreases the risk of ED. Our guide to male sexual health and performance covers exercise and erectile function in more detail.

How can I get a harder erection naturally?

The natural routes in the guidance are the lifestyle changes above, plus managing conditions that affect blood flow, such as high blood pressure, diabetes and high cholesterol. Some men also look to herbal supplements. Our guide to the science of treating ED naturally explains what the studies say, and the Red Horse section below covers one gummy the seller markets for vitality.

Can Vicks VapoRub help ED?

The Harvard Health overview of erectile dysfunction does not list Vicks VapoRub among its treatments. It lists oral drugs, alprostadil injections and suppositories, vacuum devices, psychological therapy, testosterone for low levels and penile implants. Ask a doctor before trying a home product for ED, so the real cause is identified.

How do I increase testosterone for erectile dysfunction?

Start with a blood test rather than a supplement. Harvard Health’s 2012 article calls a testosterone test a good next step, and says that if the level is low, trying testosterone replacement makes sense, and if erections do not improve, it is time to try an ED drug. Harvard Health’s A-to-Z guide says taking extra testosterone will not improve ED in general, though it may enhance sexual desire in men with abnormally low levels. A doctor can tell you whether your level is low and what to do about it.

Can high testosterone cause erectile dysfunction?

The hormone advice in the NIDDK and Harvard Health overviews is about low testosterone. Harvard Health names low testosterone as an uncommon cause of ED. If your lab shows a high result, take it to your doctor and ask what it means for your erections.

How much does erectile dysfunction surgery cost?

Costs depend on the procedure, the surgeon, your location and your insurance. Harvard Health says the cost of ED drug therapy varies with the pharmacy price, co-pays and coverage. For a penile implant or other procedure, ask the urology office for an itemized estimate and ask whether your plan covers the device.

Why am I always tired, even when I sleep a lot?

Men who feel always tired and short of energy should check the same causes that overlap with ED, including heart disease, diabetes, thyroid problems and depression. Healthline says nutrient deficiencies can leave you exhausted even when you get more than 7 hours of sleep. It lists iron, several B vitamins, vitamin D, vitamin C and magnesium. Sleep apnea is another common cause of daytime fatigue, according to MedlinePlus’s fatigue page. Cleveland Clinic’s guidance on fatigue causes and treatment lists many of the same causes.

What are three warning signs of fatigue?

Cleveland Clinic says to talk to a provider if you are tired all the time, if fatigue lasts longer than a few days, if there is no clear reason such as a recent illness, if it comes on suddenly, if you are over 65, or if you have been losing weight. Get immediate care if fatigue comes with chest, arm or upper back pain, shortness of breath, a fast or irregular heartbeat, or headache or vision problems.

What am I lacking if I’m always tired?

Cleveland Clinic names anemia and vitamin D or B12 deficiency as common causes of fatigue. Healthline lists iron, B vitamins, vitamin D, vitamin C and magnesium as nutrients linked to fatigue. A blood test is the way to find out which, if any, is low.

At what age are you most tired?

Cleveland Clinic lists being over 65 as a reason to call a provider about fatigue, so any tiredness that persists at that age is worth raising. It does not tie fatigue to one age range.

What drink gets rid of fatigue?

No drink fixes fatigue on its own. The NHS says a glass of water helps if you are mildly dehydrated, and that caffeine can disrupt sleep, with effects that last up to 7 hours, so it is best avoided late in the day. Healthline says energy drinks are extremely high in stimulants and added sugar. The NHS also says alcohol makes you sleep less deeply.

What is Red Horse Gummies, and what does the seller say?

Red Horse Gummies is a gummy dietary supplement sold to adult men. Its seller says it is made to support healthy circulation, sustained energy, vitality, physical drive and stamina. A paid press release dated October 30, 2026 calls it newly launched. The seller’s pages say it is not a treatment for ED or any other condition. One Red Horse page says, in its own words, “Does it treat ED or low T? No. It is not a treatment for erectile dysfunction, low testosterone or any other condition.” Another Red Horse page uses the headline “PERFORM IN THE BEDROOM LIKE NEVER BEFORE!” and talks about intimate moments, so the pages do not describe the product the same way.

The Red Horse name appears on several sites, and they do not describe the same product. The order buttons on these sites lead to a checkout that calls the product Horse Boost and describes a strawberry-flavored gummy. Confirm the name and flavour on the page where you pay.

Red Horse ingredients and what the research says

The reddhorse.com page lists L-arginine, tongkat ali, maca root, ashwagandha, horny goat weed, beet root and grape seed extract. The redhorsegummies.com page lists tongkat ali, horny goat weed, tribulus, maca root and L-arginine. The seller’s press release says research on individual ingredients does not establish that a finished combination product produces the same outcomes.

• L-arginine: the redhorsegummies.com page cites the VINTAGE MI trial in JAMA (2006), which it says found arginine given after a heart attack did not help and that more deaths occurred in the arginine group.
• Tongkat ali: that page summarizes a 2022 meta-analysis as finding small rises in total testosterone across trials, mostly in men with low levels, and calls those studies small and short.
• Tribulus: that page cites a 2014 systematic review that found tribulus does not raise testosterone in humans.
• Horny goat weed: that page says reliable human trials are scarce.
• Maca: that page says a few small trials suggest effects on mood or perceived well-being.
• Grape seed extract: the reddhorse.com page describes it as associated with healthy circulation and antioxidant support.

The redhorsegummies.com page also says no clinical trial has tested Red Horse Gummies as a finished product.

Safety and who should skip it

The redhorsegummies.com page says do not use Red Horse Gummies with nitrates or erectile dysfunction medicines, and it says to talk to your doctor if you take heart or blood pressure medicine. It says L-arginine and horny goat weed may lower blood pressure, and that combining them with nitrates or PDE5 drugs could cause a dangerous drop. The same page lists men with heart disease or a recent heart attack, anyone under 18, pregnant or nursing women, and anyone with surgery planned in the next two weeks as people who should avoid the product. The press release says ashwagandha may be unsuitable for people with thyroid or autoimmune conditions and for pregnant people, and it cites rare reports of liver injury with ashwagandha products.

The Food and Drug Administration’s consumer guidance says that under DSHEA, FDA does not have the authority to approve dietary supplements before they are marketed. Read the claims above as the seller’s own, and see FDA’s questions and answers on dietary supplements for how the rules work.

Before you order

• Confirm the product name, flavour, gummies per bottle and daily dose on the order page, since the Red Horse pages disagree.
• Ask the seller for the amount of each ingredient per serving from the Supplement Facts panel, which its pages say is printed on the label.
• Ask in writing which refund window applies to your order and how to start a return.
• Check shipping for your pack size before you pay.
• Tell your prescriber or pharmacist about any nitrates, ED medicine or blood pressure medicine before your first gummy.
