Do delay sprays work? For many men, yes, though the gain is a few minutes, not half an hour. A delay spray numbs the head of the penis with a local anesthetic, usually lidocaine, so stimulation takes longer to trigger ejaculation. In two large trials of a lidocaine-prilocaine spray, men who usually finished about half a minute after penetration lasted 2.6 to 3.8 minutes on average over three months. Men on a placebo spray lasted about a minute.
There are trade-offs. The anesthetic can numb your partner too, and too much numbness can cost you your erection. A spray also helps only when you use it: it buys time during sex but doesn’t teach your body to handle rising arousal. Think of it as a short-term aid, not a fix.

How delay sprays work
A delay spray for men is a local anesthetic in a small pump or aerosol bottle. You spray it on the penis before sex, and as the drug soaks in, the glans (the head of the penis) becomes less sensitive. European urology guidelines describe the effect this way: less sensitivity in the glans delays ejaculation without dulling the sensation of ejaculation itself. One explanation, according to the International Society for Sexual Medicine, is that weaker signals from the glans may dampen the spinal reflex that triggers ejaculation.
Numbing the penis is the oldest drug approach to premature ejaculation, according to both the American Urological Association and the European Association of Urology. The usual ingredients are lidocaine, prilocaine and benzocaine, alone or in combination. Cleveland Clinic says a numbing cream or spray takes about 10 to 30 minutes to absorb, though the spray in the two large trials went on just five minutes before sex.
What you can buy depends on where you live. In the European Union, a metered spray that combines lidocaine and prilocaine is approved for lifelong premature ejaculation, meaning a man has finished fast since his first sexual experience. In the US, delay sprays are sold over the counter as what FDA rules call a “male genital desensitizer,” and the label can say the product “helps in the prevention of premature ejaculation.” That isn’t the same as an FDA approval. Over-the-counter products like these can be sold without an approved drug application as long as they meet the FDA’s standard conditions for their category, which cover the allowed ingredients, uses and label.
Numbing is one way to deal with a sensitive penis. The other is training, and our guide on how to reduce penis sensitivity naturally covers it.
Do delay sprays work? What the trials show
The strongest evidence comes from two large trials of the lidocaine-prilocaine spray approved in Europe. Both enrolled men with lifelong premature ejaculation. To qualify, a man had to finish within a minute of penetration in at least two of his first three encounters during a four-week screening period. For three months, the men applied either the spray or a placebo spray five minutes before sex and timed every encounter with a stopwatch.
In the European trial, 300 men in stable relationships took part. Their average time from penetration to ejaculation rose from about 36 seconds to 3.8 minutes on the spray, and to 1.1 minutes on the placebo. By the end, two-thirds of the men on the spray rated it good or excellent. A second trial, with 256 men in the US, Canada and Poland, found a smaller gain: from about 34 seconds to 2.6 minutes on the spray, against 48 seconds on the placebo. In both trials, men on the spray also scored better than the placebo group on questionnaires about control and satisfaction.
Reviews that pool the research agree that numbing products beat a placebo, but they differ on how solid the evidence is. A 2016 review of nine trials rated the quality of most as unclear and found conflicting results on whether men felt more satisfied or in control. A 2025 overview of 44 meta-analyses, or pooled reviews, was more confident: of all the drug options it examined, only topical anesthetics and one antidepressant, paroxetine, had evidence rated moderate to high in certainty.
Both major guidelines put numbing products near the top of the list. European urologists name the lidocaine-prilocaine spray as a first-choice option for lifelong premature ejaculation, and the American Urological Association includes topical penile anesthetics among its first-choice drug options.
Lidocaine-only sprays, the kind sold over the counter in the US, weren’t part of those two trials, but urologists in Europe consider them effective as well. In one trial in Egypt, 150 men with lifelong premature ejaculation used either a 5% lidocaine spray or an alcohol spray as a placebo for eight weeks, leaving it on for 10 to 20 minutes and cleaning it off before sex. The men on lidocaine lasted longer than the placebo group, a statistically significant difference.
Keep in mind who was in the big trials: men with lifelong premature ejaculation who usually lasted well under a minute. The trials say little about men who already last several minutes and want more.
Delay spray side effects for you and your partner
For the lidocaine-prilocaine spray, side effects were uncommon and stayed local. European guidelines report genital numbness in 4.5% of men and 1% of female partners, erection problems in 4.4% of men and a burning sensation in 3.9% of partners. Effects elsewhere in the body are unlikely. When researchers pooled trials of numbing products in general, side effects were about four times as common as with a placebo, though nearly all were mild and brief.
Your partner can feel the numbness as well, because anesthetic left on the skin can rub off during sex. The International Society for Sexual Medicine warns that some numbing products can cause vaginal numbness and keep a female partner from reaching orgasm unless you wear a condom. The lidocaine-prilocaine spray’s formulation kept such reports to a minimum in its trials, but that result may not apply to other products.
Numbness can also cost you your erection. In a small study from 2002, 30 men applied a numbing cream, covered it with a condom and left it on for different lengths of time before sex. After 20 minutes, they lasted longer without side effects. After 30 minutes, six of 10 lost their erection because of the numbness, and after 45 minutes, all 10 did. In an early spray study, occasionally a man had trouble keeping his erection while he waited for the spray to work. If you lose your erection easily, our guide on how to stay hard covers what helps during sex.
Skip any of these products if you or your partner is allergic to an ingredient. If you’re trying to conceive, European urologists advise avoiding lidocaine-prilocaine products because the drugs may harm sperm.
How to use a delay spray more safely
These steps come from US labeling rules and medical guidance. Your product’s own directions come first.
- Apply it where the label says. US rules say to apply desensitizers to the head and shaft of the penis before sex. In the two large trials, the spray went on the glans five minutes before sex.
- Don’t use more, or leave it on longer, than the label says. More numbness isn’t more control, and as the cream study above showed, longer contact cost men their erections.
- Protect your partner. Cleveland Clinic advises washing your penis before sex so the anesthetic doesn’t numb your partner, and in the Egypt trial, men who cleaned the spray off before sex still lasted longer. Guidelines also suggest a condom as a barrier.
- Wash it off afterward. That’s part of the US label directions.
- Keep it away from your eyes.
- Stop if either of you gets a rash, burning or itching, and see a doctor if it doesn’t clear up.
Sprays, creams, wipes and numbing condoms compared
Sprays aren’t the only way to numb the penis. The other formats work the same way but have different evidence behind them.
| Format | What the research shows | Trade-offs |
|---|---|---|
| Lidocaine-prilocaine spray | Two large trials: average time rose from about half a minute to 2.6–3.8 minutes | Approved in Europe; numbness and erection problems in a few percent of men |
| Lidocaine-only spray | Not in the two big trials; guidelines call these sprays effective | The over-the-counter type in the US; can numb a partner unless washed off |
| Numbing cream or gel | Guidelines cite studies in which time rose from 1–2 minutes to 6–9 minutes; those men started out lasting longer than the men in the spray trials | Left on too long, it can cost you your erection |
| Delay wipes | Little published research | Same partner and skin precautions as other desensitizers |
| Numbing condom | A 5% benzocaine condom added about a minute over a regular condom in a 2026 trial | Tested in men who only sometimes felt sex ended too soon |
The condom trial, run by researchers at a condom maker, has a twist. Among 148 men who sometimes felt sex ended too soon, a plain condom alone added almost two minutes compared with their usual timing. The 5% benzocaine version added about a minute more on top of that, and a 3% version didn’t beat the plain condom by a significant margin.
What a delay spray can’t do
A spray changes what you feel, not how you respond to it. Here’s the short version:
| A delay spray can | A delay spray can’t |
|---|---|
| Dull sensation in the head of the penis within minutes | Teach you to notice and manage rising arousal |
| Add a few minutes, on average, for men with lifelong premature ejaculation | Promise a set number of minutes |
| Help on the occasions you use it | Offer proof of lasting benefit: long-term outcomes are unknown |
| Improve ratings of control and satisfaction in the large trials | Fix the worry or erection problems behind a fast finish |
European guidelines say the long-term outcomes of drug treatments for premature ejaculation, sprays included, are unknown. Real life also looks different from a trial. An Italian clinic followed 198 men with premature ejaculation who were new to treatment: by six months, 184 had tried the lidocaine-prilocaine spray and 128 were using it regularly, but at one year only 53 still were.
A spray also works on only one part of the problem. If worry about sex is what speeds you up, numbing the skin doesn’t reach the cause. When premature ejaculation starts after years of normal timing, the guidelines put treating the underlying cause first, and anxiety is one of the causes they name. Our guide to sexual performance anxiety has practices for managing it.
Training targets how you respond. Those guidelines also say exercises such as the stop-start technique improve symptoms when combined with mindfulness and education about premature ejaculation. They add that pairing this kind of training with medical treatment works better than medical treatment alone. The same guidelines rate the evidence for training on its own as weak and inconsistent, with unknown long-term results, so no option here is a sure thing.
That’s why we see a delay spray as training wheels: something to lean on now and then while you train yourself to last longer, not a replacement for the training. Use it sparingly, because the skill you’re practicing is handling full sensation, and numbness leaves you less of it to work with. Our guide on how to stop premature ejaculation lays out the other options.
Train the skill a spray can’t teach
The Coach app’s Last Longer program teaches breathing, relaxation and arousal control in an eight-week plan you start on your own. The quiz asks about your sex life now and tailors the plan to your answers.
When to see a doctor
Delay sprays are sold without a prescription in the US, yet the required label itself says premature ejaculation may be due to a condition that needs medical supervision. See a doctor if:
- a spray used as directed doesn’t help. US labels tell you to stop using it and talk to a doctor.
- you or your partner gets a rash, burning or itching that doesn’t clear up.
- you also have trouble getting or keeping an erection. American and European guidelines say to treat erection problems first.
- your timing changed after years of lasting longer. Guidelines name causes worth checking, such as prostatitis (prostate inflammation), urinary symptoms, thyroid problems and erection trouble.
- finishing early bothers you or your partner, whatever you’ve tried. A doctor can talk through other options, including prescription medicines.
Our premature ejaculation overview explains what counts as the condition and where short-term approaches aren’t enough.
Training control with The Coach, spray or no spray
We make The Coach, a sexual wellness app, and its Last Longer program takes the same view of delay sprays: training wheels you use sparingly while you build control. Over eight weeks, starting solo and bringing in a partner later, it works on what a spray can’t touch: relaxing your body, reading your arousal on a 1–10 scale, breathing slowly through intense moments and strengthening your pelvic floor.
The method works at two levels of arousal. Before arousal gets close to the edge, breathing, relaxation and awareness are how you keep it in check. Near the edge, a pelvic floor trained with Kegel exercises is meant to act as a backup brake. Guided breathing and relaxation sessions are part of the daily plan, and a six-week Kegel program comes with reminders.
Phone-based training like this has some early support. European guidelines report positive effects from a smartphone program aimed at the skills behind lasting longer and at sexual self-confidence. That was a different program, not The Coach.
In The Coach’s own survey of men after their first four weeks, 58% said they felt more in control during sex. It’s training, not a medical treatment, and it can’t promise you a number of minutes. If anything in the doctor section above applies to you, start there.

Questions about delay sprays
Is a delay spray better than Viagra?
They do different jobs. A delay spray numbs the penis to slow ejaculation, while Viagra (sildenafil) is an erection drug. On timing alone, numbing came out ahead in a head-to-head trial included in a 2016 review: a lidocaine gel delayed ejaculation more than sildenafil. In studies summarized in European guidelines, sildenafil didn’t significantly lengthen the time to ejaculation, though men felt more confident and more in control. Cleveland Clinic says erection medicines may help with premature ejaculation, particularly when erection problems are also present. If you struggle with erections too, see a doctor: guidelines say to treat that first.
Can a delay spray make you last 30 minutes?
Don’t count on it. In the two large trials of a lidocaine-prilocaine spray, average times on the spray were 2.6 to 3.8 minutes. For perspective, a stopwatch study of 500 couples in five countries found a median of 5.4 minutes from penetration to ejaculation, with a range from about half a minute to 44 minutes. Our guide on how long sex should last puts those numbers in context.
