Stud 100 Desensitizing Spray for Men - 12g

What Is Stud 100 Desensitising Spray for Men?

Premature ejaculation is one of the most common sexual concerns among men in the UK. It affects an estimated one in three men at some point in their lives, according to the NHS. If you've been looking for a straightforward, over-the-counter option, desensitising spray for men like Stud 100 is one of the most widely recognised choices available without a prescription. At just £6.99 for a 12g can, it's an accessible starting point for many men. You can explore a wider range of products in our condoms and sexual health collection.

Stud 100 has been available in the UK for decades and is manufactured to a consistent standard. It contains lidocaine 9.6% as its active ingredient — a well-established local anaesthetic used across many areas of medicine. The spray is applied directly to the penis before intercourse to temporarily reduce sensitivity, helping men maintain control for longer.

How Does Stud 100 Desensitising Spray Work?

The mechanism is straightforward. Lidocaine works by blocking sodium channels in nerve cell membranes, which temporarily interrupts the transmission of sensory signals. Applied topically to the penis, it reduces the intensity of physical stimulation without eliminating sensation entirely. Here's how the process works:

• Lidocaine is absorbed through the skin of the glans and shaft of the penis.
• It binds to voltage-gated sodium channels in local sensory nerve endings.
• This slows or blocks nerve impulse conduction, reducing the sensation of stimulation.
• The effect is temporary and reversible — normal sensation returns as the lidocaine disperses.

Importantly, Stud 100 does not affect the ability to achieve or maintain an erection. It targets sensory nerves only, not the vascular or autonomic mechanisms involved in erectile function.

Who Should Use Stud 100 Desensitising Spray?

Stud 100 is intended for adult men who experience premature ejaculation and want a non-prescription, topical option to help manage it. It may suit you if:

• You regularly ejaculate sooner than you or your partner would like during intercourse.
• You have no known allergy to lidocaine or other amide-type local anaesthetics.
• You are looking for an on-demand solution rather than a daily oral medication.
• You want a discreet, easy-to-use product that doesn't require a GP visit.

It is not suitable for men with broken, inflamed, or infected skin on the penis, or for those with known hypersensitivity to lidocaine. If you have an underlying condition affecting penile sensation — such as peripheral neuropathy — speak to your GP before use.

How Does Stud 100 Compare to Other Delay Products?

Is Stud 100 Suitable for Long-Term Use and How Should It Be Stored?

Stud 100 is designed for use on an as-needed basis rather than as a daily treatment. There is no established maximum duration of use, but if premature ejaculation is persistent and significantly affecting your quality of life, it's worth speaking to your GP about additional options — including behavioural therapy or prescription treatments. The NHS recommends a combined approach for long-term management of premature ejaculation.

Store the can below 25°C, away from direct sunlight and heat sources. Do not puncture or incinerate the aerosol, even when empty. Keep out of reach of children. If you're also managing other aspects of your sexual health, our men's health collection includes a range of relevant products. The desensitising spray for men format makes Stud 100 easy to apply accurately and hygienically each time.

This product is a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

What Is Stud 100 and What Is It Used For?

Stud 100 Desensitizing Spray for Men is an over-the-counter topical aerosol spray containing lidocaine 9.6% as its active ingredient. It is used to temporarily reduce sensitivity in the penis, helping men who experience premature ejaculation to delay ejaculation during sexual intercourse. Premature ejaculation is defined by the NHS as ejaculating sooner than you or your partner would like, and it is considered the most common male sexual dysfunction. Stud 100 is not a cure, but it can be a helpful on-demand aid as part of a broader approach to managing the condition.

What Do You Need to Know Before Using Stud 100?

Before using this product, read the following carefully. Do not use Stud 100 if any of the following apply to you:

• You are allergic to lidocaine, any other amide-type local anaesthetic, or any other ingredient in the spray.
• You have broken, inflamed, infected, or damaged skin on the penis.
• You have a condition that causes reduced or absent penile sensation — using a desensitising agent could mask important sensory feedback.
• Your partner is pregnant — lidocaine transfer during intercourse should be avoided in pregnancy unless a condom is used.
• You are under 18 years of age.

Speak to your pharmacist or GP before use if you have any neurological condition, are taking other medicines applied to the skin, or have a history of sensitivity to local anaesthetics.

Drug interactions: No significant systemic drug interactions are established at the topical doses used in Stud 100. However, caution is advised if you are using other topical anaesthetic products simultaneously, as combined use could increase the risk of systemic absorption and side effects.

• Avoid concurrent use with other lidocaine-containing topical products.
• If you are taking antiarrhythmic medicines (e.g. mexiletine), speak to your GP before use, as lidocaine shares a similar mechanism.

How Should You Use Stud 100 Correctly?

Using Stud 100 correctly is important both for effectiveness and to minimise the risk of transferring lidocaine to your partner. Follow these steps:

1. Shake the can gently before use.
2. Hold the can upright and apply 3 sprays to the head (glans) and shaft of the penis.
3. Gently massage the spray into the skin.
4. Wait 5–15 minutes to allow the lidocaine to absorb fully before sexual contact.
5. If the effect is insufficient, you may increase to a maximum of 8 sprays — do not exceed this.
6. If your partner may come into contact with the treated area, use a condom to prevent transfer.

What Are the Possible Side Effects of Stud 100?

Like all medicines, Stud 100 can cause side effects, although not everyone experiences them. If you notice any unexpected reaction, stop use and seek advice from a pharmacist or GP.

Common side effects:

• Mild burning or stinging sensation at the application site immediately after spraying.
• Temporary skin irritation or redness on the penis.
• Reduced sensation in a partner if lidocaine transfers during intercourse.

Less common side effects:

• Allergic contact dermatitis — itching, rash, or swelling at the application site.
• Excessive numbness making intercourse difficult or unsatisfying.
• In rare cases, systemic absorption of lidocaine may cause dizziness or light-headedness if used in very large amounts — do not exceed 8 sprays.

If you or your partner experience signs of a serious allergic reaction — such as swelling of the face, lips, or throat, difficulty breathing, or a widespread rash — stop use immediately and seek emergency medical attention. You can find further information about managing skin reactions through our skin care collection if mild irritation persists after use.

How Should You Store Stud 100 Safely?

Correct storage keeps the product safe and effective for its full shelf life. Follow these instructions:

• Store below 25°C in a cool, dry place away from direct sunlight.
• Do not store near heat sources, open flames, or in a car glove compartment in warm weather — the can is pressurised.
• Do not puncture, crush, or incinerate the aerosol can, even when empty.
• Keep out of the reach and sight of children.
• Do not use after the expiry date printed on the can.
• Do not freeze.
