Who Invented the Dildo?
The remarkable 28,000-year history of the dildo — from Ice Age stone carvings to the invention of medical-grade silicone and the modern sex toy industry.
Shop DildosNo other manufactured object has been continuously used for pleasure across such an extraordinary span of human history. The dildo appears in the archaeological record of nearly every major civilisation, in mythology, in literature and in law. This guide traces that history from the earliest known examples to the invention of the modern body-safe toy.
The Stone Age: 28,000 BCE
The oldest confirmed phallic object used for sexual pleasure was discovered in 2005 by researchers from Tübingen University, exploring the Hohle Fels Cave in Germany's Swabian Jura region. Made from siltstone and approximately 20 centimetres long, this Ice Age artefact dates to approximately 28,000 years ago. Its shape, surface detail and polish are consistent with sexual use rather than ceremonial function.
It is not the only such discovery. Archaeological sites across Eurasia — including a Mesolithic site in Motala, Sweden, and sites in Pakistan — have yielded phallic objects dating back 4,000 to 6,000 years. Archaeologists once catalogued many of these cautiously as "batons" or "ritual objects," but scholarly opinion has shifted significantly toward accepting their sexual purpose.
More recently, a 2,000-year-old wooden phallus was unearthed at the Roman fort of Vindolanda in Northumberland. It was originally catalogued as a darning tool before researchers concluded its actual function was considerably less mundane.

The modern dildo as we know it owes its existence to Gosnell Duncan, a man who needed one and could not find a safe one. In 1965, Duncan sustained an injury that left him paralysed from the waist down. Seeking a penile substitute, he found that the available options were made from low-grade rubber that could not withstand heat or proper cleaning.
Duncan worked with a chemist to develop a dildo from medical-grade silicone — the same material used in surgical implants. The resulting toy was non-porous, heat-resistant, sterilisable and safe for internal use. It was a genuinely revolutionary product: for the first time in 28,000 years of history, the dildo was made from a material that could be properly cleaned.
Duncan's invention came just as the sexual revolution was transforming attitudes toward masturbation and sexual pleasure. The 1960s and 1970s saw the dildo reframed by feminist sex educators as a tool for women's sexual autonomy rather than a substitute for male anatomy. Innovators like Betty Dodson popularised smooth, colourful, non-phallic silicone designs that shifted the aesthetic of the entire category.
The Dildo Today
The modern sex toy industry is worth tens of billions of pounds globally. In the UK, approximately 30 per cent of adults report owning at least one sex toy. Dildos are sold in mainstream pharmacies, high street shops and online retailers across the country. The materials have expanded from Gosnell Duncan's original silicone to include borosilicate glass, surgical stainless steel and dual-density designs that replicate the feel of biological anatomy more closely than anything in the preceding 28,000 years.
Bluetooth connectivity, app control and temperature regulation represent the most recent innovations. The fundamental purpose — pleasurable penetration — remains entirely unchanged from the object found in Hohle Fels Cave.
