Topical anaesthetic spray delays ejaculation by five times as long says new study

25.01.2007
Patients with premature ejaculation who used a topical anaesthetic spray were able to delay ejaculation for five times as long, according to a study in the February issue of the urology journal BJU International.

Researchers from the UK and Netherlands studied 54 men with premature ejaculation, randomly assigning them to a treatment and control group. Both groups reported that without any therapy they normally ejaculated an average of one minute after vaginal penetration.

“The men who were prescribed the TEMPE spray, which delivers a combination of lidocaine and prilocaine, managed to delay ejaculation by just under an extra four minutes after using the product” reports Professor Wallace Dinsmore from the Royal Victoria Hospital, Belfast.

“Meanwhile the control group, who were prescribed a placebo (dummy) spray, increased their penetration to ejaculation time by just over 40 seconds.

“Overall, the TEMPE spray was 2.4 times more effective than the placebo.”

The study focussed on heterosexual couples who had been in a stable monogamous relationship for at least three months and were willing to attempt sexual intercourse on at least seven occasions during the ten-week study period.

Recruited from six hospitals and medical centres across the UK – Sheffield, Manchester, Durham, Plymouth, Belfast and, London – and one in The Hague, the men were aged from 18 to 75, with an average age of 39.

Time since diagnosis ranged from seven months to just under 35 years, with an average of nine and a half years.

The men in the TEMPE group (Topical Eutectic Mixture for Premature Ejaculation) administered three metered sprays of the local anaesthetic preparation to the glans of their penis 15 minutes before intercourse. This delivered a total of 22.5mg of lidocaine and 7.5mg of prilocaine.

The placebo group were issued with an identical container that delivered a spray without any active ingredients. Both groups were advised not to use the spray more than once in any 24-hour period to avoid possible bias resulting from too frequent ejaculation.

Participants were also issued with a stopwatch so that they, or their partner, could measure the time lapse between penetration and ejaculation.

20 TEMPE users and 23 placebo users completed the study and 83 per cent of all users found the spray easy to use.

The majority of the TEMPE users and their partners tolerated the spray well. Three men reported numbness in their penis, one said he was unable to get an erection and one partner reported a mild burning sensation each time the spray was used, but continued with the treatment.

No adverse effects were found during patient safety checks, which included vital signs, physical findings, electrocardiograms, haematology, biochemistry and urine analysis.

“At the moment, only a small number of men with premature ejaculation seek or receive treatment from a healthcare professional and the lack of effective pharmacological treatment is a contributory factor” concludes co-author Dr Michael Wyllie from Plethora Solutions Ltd, which manufactures the TEMPE spray.

“The encouraging data from this phase two study suggests that TEMPE has the potential to offer a convenient, novel treatment for men with premature ejaculation and might be useful as a first-line treatment for the condition.”

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
