Rationale - STUD 100® and Premjact® Desensitizing Sprays for Men

STUD100® and Premjact® are Male Genital Desensitizers containing Lidocaine in a metered dose pump spray for topical use. They provide surface anesthesia to the penis for the reduction of tactile sensitivity in the male in advance of intercourse. The Medical rationale for the use of these products involves the need to delay ejaculation where it poses a problem of anxiety regarding sexual performance and consequently a reduction in self-confidence. As the female sexual response is usually slower than that of the male, a delay in ejaculation benefits both partners. Continued precipitant ejaculation could lead to more serious psycho-physiological problems of premature ejaculation which are much more difficult to treat.

There are a number of Clinical Trials described in our Product Overview which, taken together, are convincing evidence of the product's efficacy. These include a controlled clinical pharmacological test of reduction in sensitivity of the penis after application, delay in masturbation time and continued use of the products over several years by users. The safety of the products has been demonstrated by Clinical Trials covering absorption, irritation and sensitization potential as well as the in-use evidence from over 20 years of marketing.

The products are identical in every way and are both licensed by the MHRA (Medicines and Healthcare Products Regulatory Agency) in the UK, and meet all of the requirements of the monograph on Male Genital Desensitizers set out by the FDA in the USA. The products are fast-acting, safe and effective and produced in the UK under current EU, US and WHO Good Manufacturing Practices.
