Although no industry market data is available for the “last longer in bed” market, Promescent and K-Y Duration™ appear to be the two leading brands of last longer products available in the U.S. based upon articles in the media, advertising and widespread availability in retails stores. Promescent has been available since 2011 and K-Y Duration™ was introduced in 2016. Both products are lidocaine-based, desensitizing sprays available over-the-counter by way of the FDA monograph: 21 CFR 348.10.
User reviews of each product are available on-line, but given the nature of crowd-sourced (stars) reviews, many consumers look for additional information that enable a more informed decision-making process when choosing a product, especially one of a medical nature that involves a sexual partner. Consumers look for products that are effective, easy-to-use and have minimal side effects.
There are four issues that informed consumers may want to know to help them choose the last longer spray that best meets both his and his partner’s needs.
At the time of this writing, January 2017, an internet search for clinical data that reviews the performance of K-Y Duration™ has revealed no results. Promescent appears to be the only desensitizing spray available in the U.S. that has clinical data for effectiveness including sexual satisfaction and side effects. The clinical survey conducted by the University of Kentucky, published in the International Journal of Impotence, showed that men lasted 64% longer when using Promescent. In addition, both partners achieved orgasm when using Promescent at a 50% greater frequency than without using the product.
Absorption Pharmaceuticals, makers of Promescent, claims that the successful performance in this study is a result of the absorption formula, which the company says enables a man to gain ejaculation control with minimal loss of sensation and minimal transference of the active ingredient, lidocaine, to his partner.
Promescent is established as first-line therapy for helping men delay ejaculation by more than 1,500 urologists in the USA as well as a growing number of sex therapists. When urologists cite their reasons for recommending Promescent, highest on their list is the minimal side effects – most notably that the user maintains good sensation with negligible transference to his partner.
Because K-Y Duration™ was only introduced in 2016, one cannot expect very many product reviews in the media. However, articles have been written specifically about Promescent or the product has been included in articles about sexual health or trends in male sexuality, notably the increased attention on the length of time of sex as well as partner pleasure. A list of publications and other media includes Men’s Health, Men’s Fitness, Esquire, The Atlantic, Business Insider, CNN, CNBC, Cosmopolitan, the National Post, Chicago Sun-Times, Huffington Post, Glamour, SheKnows along with numerous terrestrial and satellite radio shows.
K-Y Duration™ is manufactured in Thailand. Promescent is produced in North Carolina in a 180,000-square foot, state-of-the-art pharmaceutical manufacturing facility. Absorption Pharmaceuticals, the makers of Promescent, is strictly a pharmaceutical company with 100% of its employees in the USA. Reckitt Benckiser, the maker of K-Y Duration™, sells a wide variety of household and personal care products and is headquartered in Europe.
