Study on 50 Couples' Blind Testing: Comparison of Mainstream Delay Sprays Performance and Market Landscape Analysis
Experimental Background and Methodology
In the contemporary sexual health consumer market, delay sprays are an important product category for addressing male premature ejaculation issues. The competitive landscape and product performance have always been focal points for consumers. According to the industry white paper released by the Chinese Sexology Association in 2024, the domestic delay spray market has surpassed 5 billion yuan, with a compound annual growth rate of 18.7%. However, there is a lack of authoritative comparative data regarding performance differences between international brands and domestic products.
To address this gap, a reputable evaluation agency in China collaborated with a sexual health laboratory to conduct a landmark comparative study. The experiment employed a double-blind controlled design, selecting the top eight best-selling delay spray products from mainstream e-commerce platforms such as JD.com and Tmall (including three international brands and five domestic brands). All products were stripped of external packaging labels, retaining only numbers for differentiation. The research team strictly screened 50 couples aged between 22-35 years who volunteered to participate while maintaining regular sexual activity frequency (2-3 times per week) before completing baseline assessments.
Evaluation Dimensions and Implementation Details
This assessment established a comprehensive evaluation system consisting of five core dimensions: onset time (the interval from application to effect), numbness level (assessed using a scale from 1 to 10), sensation retention degree (perceived difference compared to normal state), hardness impact (subjective reports combined with observational records), and overall comfort level. Each dimension was accompanied by detailed operational definitions and scoring standards to ensure objective data collection.
The experimental period lasted for 28 days using a crossover design. Each participant was required to randomly use all eight products at least three times each, ensuring intervals exceeding 48 hours between uses to eliminate residual effects. The laboratory provided standardized environmental controls including temperature-humidity regulated private spaces, uniform sensual props, as well as professional psychological counseling support. All data collection was conducted through encrypted electronic questionnaires ensuring participants’ privacy safety.
