Durex is one of the world’s most recognized condom brands, yet few people know what its name actually stands for. The company traces its roots back to 1915, when it began as the London Rubber Company. By 1929, it had secured the Durex trademark, laying the foundation for a global brand that would become synonymous with protection and intimacy.

Over the decades, Durex established itself as an innovator in the industry. By the 1950s, its products were sold worldwide. The company introduced the first anatomically shaped condoms, pioneered electronic testing, and was the first condom brand to advertise internationally in the 1970s. Later innovations included latex-free, flavored, and textured varieties, further expanding its reach and reputation.

For years, many assumed “Durex” was simply shorthand for “during sex.” But the truth is more practical and rooted in quality. According to the BBC, the name actually stands for Durability, Reliability, and Excellence—a reflection of the brand’s commitment to trust and safety. Every condom undergoes electronic and dermatological testing, underscoring the company’s long-standing focus on reliability.

This revelation has surprised many online, sparking both humor and admiration. Some joked about the clever branding, while others noted they only discovered the meaning while studying marketing strategies. Beyond the laughs, though, the name captures Durex’s enduring legacy. For nearly a century, its promise of durability, reliability, and excellence has helped it remain at the top of the industry and one of the most trusted names worldwide.
