Bringing sex toys out of the dark: exploring unmitigated risks
AI summary Read the abstract
Researchers found that four types of commercially available sex toys released micro- and nanoplastics during abrasion testing and contained phthalate endocrine disruptors exceeding hazard thresholds, identifying a largely unregulated category of consumer products with potential for direct intimate exposure to plastic particles and chemicals.
UNLABELLED: A majority of American adults report having used sex toys, which, by design, interact with intimate and permeable body parts yet have not been subject to sufficient risk assessment or management. Physical and chemical data are presented examining potential risks associated with four types of currently available sex toys: anal toy, beads, dual vibrator, and external vibrator. A standardized abrasion machine made real-time breakdown of products into microplastics and nanoplastics. The microplastics from the sex toys were then solvent extracted and analyzed using GC-MS. Rates of microplastics and nanoplastics released during abrasion testing from most microplastic release to least was the anal toy, beads, dual vibrator, external vibrator. Both micro- and nanoplastics particles were generated following the abrasion test, with the 50 percentile diameters (D50) ranging from the anal beads at 658.5 μm, dual vibrator at 887.83 μm, anal toy at 950 μm, and external vibrator at 1673.33 μm. The material matrix of each product was analyzed using ATR-FTIR, with results identifying the anal toy as polyethylene terephthalate (PET), the anal beads as polyvinyl chloride (PVC), the external vibrator as a silicone blend (polydimethylsiloxane [PDMS]), and the dual vibrator as a rubber mixture (polyisoprene). After extraction, phthalates known to be endocrine disruptors were present in all tested sex toys at levels exceeding hazard warnings. Analogous findings have been reported for similar materials that, when incorporated into other product categories, are subject to regulatory scrutiny in both the US and EU. This data set is not intended to be representative of sex toys as an entire class of products, nor are the abrasion experiments claiming to simulate exact use conditions. However, these exploratory data frame potential concerns, highlighting research questions and the need for prompt prioritization of protective action. Therefore, future studies and multi-stakeholder action are needed to understand and reduce risk for this class of products.

Sex toys for pleasure, but there are risks: In silico toxicity studies of leached Micro/Nanoplastics and phthalates
AI summary Read the abstract
Researchers used computer modeling to investigate potential health risks from micro- and nanoplastics and phthalates that can leach from sex toys during use. The study found that these leached compounds may interact with key human enzymes involved in drug metabolism and immune function. Evidence indicates that polyethylene, polypropylene, polystyrene, and polyamide particles, along with several phthalates, showed varying levels of potential immunotoxicity in the simulations.
