Erectile Dysfunction & Male Sexual Health
A plain-English resource on erectile dysfunction and male sexual health: the medications and treatments that work, how Viagra/sildenafil behaves and interacts, what causes ED, the questions women ask, and practical matters like buying and prescriptions.
Erectile dysfunction (ED) is the recurring difficulty getting or keeping an erection firm enough for sex. It is one of the most common male sexual health concerns, becomes more frequent with age, and in the large majority of cases it can be treated. Knowing which treatments actually work — and which do not — is the first step to dealing with it sensibly.
This section is a plain-English resource on ED and male sexual health, written for anyone who wants reliable information before talking to a clinician. It covers the medications and treatments that work; how Viagra (sildenafil) behaves, its side effects and interactions; what causes ED, from neurological conditions to hormones; the questions women ask about these drugs; and practical matters such as buying online and NHS prescriptions. ED medications are prescription-only and can interact dangerously with other drugs, so a clinician should always be involved.
Use the comparison table and topic sections below to find what you need, and start with the medications guide if you are weighing your treatment options.
ED treatment options at a glance
Several approaches are promoted for ED, but they vary enormously in how well they are proven. The table below is a general overview; most options that genuinely work require a prescription.
| Approach | How it works | Prescription needed | Notes |
|---|---|---|---|
| Oral PDE5 inhibitors (sildenafil, tadalafil) | Improve blood flow during arousal | Yes | The proven first-line treatment |
| Supplements (L-arginine) | May support nitric oxide and blood flow | No | Evidence is modest |
| Natural remedies (watermelon/citrulline) | Possible mild effect on blood flow | No | Largely unproven |
| Delay sprays | Numb the skin to delay ejaculation | No | For premature ejaculation, not ED itself |

Best delay sprays for long-lasting performance in bed.

Read moreBuy Viagra online in Australia.
You can buy Viagra online in Australia, but only with a prescription from an Australian-registered doctor, usually via an online assessment and a licensed pharmacy.
Read moreCan aspirin help with erectile dysfunction?
Aspirin may help erectile dysfunction in some men, particularly when the cause is arterial, but the evidence is mixed and it is not an approved ED treatment.
Read moreCan viagra pills be white?
Viagra pills can be white: sildenafil comes in different colours, and after the patent ended a cheaper white version appeared, as did generic sildenafil.
Read moreCan high testosterone levels cause erectile dysfunction?
High testosterone levels are not a recognised cause of erectile dysfunction; it is low testosterone and hormonal imbalance that are associated with ED.
Read moreCan multiple sclerosis cause erectile dysfunction and what is the best treatment?
Multiple sclerosis can cause erectile dysfunction because it damages the nerves that erections depend on, but it is treatable — PDE5 inhibitors work for many men.
Read moreCan viagra affect mood and cause personality changes?
Viagra is unlikely to cause genuine mood or personality changes: it is not psychoactive, and there is no solid evidence that sildenafil alters mood directly.
Read moreCan Viagra or Sildenafil affect heart rate?
Viagra can cause small, short-term effects on heart rate and blood pressure, but for most people these are minor and not clinically significant.
Read moreCan women experience erectile dysfunction?
Women do not get erectile dysfunction in the literal sense, but they can experience female sexual dysfunction — difficulties with desire, arousal, lubrication or orgasm.
Read moreCan women take tadalafil (Cialis) and what are the effects?
Women should not take tadalafil (Cialis) for sexual dysfunction: it is not approved, the evidence is lacking, and off-label use carries risks like a blood-pressure drop.
Read moreCan you take viagra or sildenafil with diazepam?
There is no well-established dangerous interaction between Viagra and diazepam, but both can affect blood pressure, so combining them needs medical advice.
Read moreDoes viagra affect ejaculation during sex?
Viagra does not directly control ejaculation, but by improving erections it can boost confidence and shorten the refractory period; it does not treat premature ejaculation.
Read moreHomeopathic remedies for erectile dysfunction.
Homeopathic remedies are widely promoted for erectile dysfunction, but there is no good evidence they work; any benefit is most consistent with a placebo effect.
Read moreHow to cure erectile dysfunction permanently?
Erectile dysfunction can often be cured permanently when it has a reversible cause — frequently lifestyle, psychological or a treatable medical condition.
Read moreHow to stimulate a man with erectile dysfunction?
Stimulating a man with erectile dysfunction is about intimacy, patience and communication as much as touch — and an erection is not necessary for sexual pleasure.
Read moreIs viagra free on prescription in the uk?
Viagra is not automatically free on the NHS, but sildenafil can be prescribed and charges are reduced or waived for many; Viagra Connect is an over-the-counter option.
Read moreIs watermelon a natural viagra?
Watermelon is sometimes called a natural Viagra because it is rich in L-citrulline, which supports nitric oxide and blood flow — but the effect is mild and unproven for ED.
Read moreMedications for erectile dysfunction treatment.
The medications for erectile dysfunction that work are the prescription PDE5 inhibitors — sildenafil, tadalafil, vardenafil and avanafil — which improve blood flow during arousal.
Read moreDoes Viagra cause gastrointestinal side effects?
Viagra can cause gastrointestinal side effects such as indigestion and an upset stomach, usually mild; psychological or mood effects are far less typical.
Read moreUsing l-arginine for erectile dysfunction.
L-arginine is a popular ED supplement with a plausible rationale — it boosts nitric oxide — but the evidence is modest and weaker than for prescription medicines.
Read moreWhat are the side effects of sildenafil?
