A typical sex doll’s anatomy is carefully designed to replicate human features and provide a realistic experience. The core structure usually consists of a skeleton made from metal or high-strength plastics, which offers stability and support. This internal framework allows for movement and positioning, especially in movable models.
The outer layer is predominantly made of silicone or thermoplastic elastomers, materials chosen for their skin-like feel, flexibility, and durability. These materials are often infused with pigments to replicate realistic skin tones and textures. The head may include intricately crafted features such as detailed eyes, eyelashes, and removable or customizable hair. The torso and limbs are designed with realistic muscle tone and proportions, enhancing the lifelike appearance.
Internally, many sex dolls contain a hollow cavity or a reinforced core that houses the internal wiring for movable joints or heating elements. Some models include silicone or TPE (thermoplastic elastomer) cavities that mimic musculature and internal organs, adding to the realism. While most dolls do not feature complex internal organs, their construction aims to create a convincing and immersive experience through detailed external anatomy and responsive features.
