FemmyCycle · Menstrual Cups
Diva Cup #1 Pre-Childbirth
Lower PFAS concern; silicone menstrual cups rarely require PFAS treatments, but brand provides no transparency.
The Diva Cup is made from medical-grade silicone, a material category with inherently lower PFAS risk compared to coated or water-resistant products. The brand does not publicly disclose or make claims about PFAS. No independent lab testing or third-party PFAS verification is documented for this product.

The full breakdown
What it's made of and why it matters
The Diva Cup #1 is manufactured from medical-grade silicone, a synthetic polymer that does not require Teflon-type coating or water-repellent coatings to function. Silicone is considered inert during body contact; it does not leach BPA, phthalates, or other endocrine disruptors under normal use conditions (body temperature, pH-neutral vaginal environment). The material is inherently non-porous when properly manufactured, which minimizes bacterial colonization compared to alternative materials. Medical-grade silicone is FDA-cleared for prolonged internal use and has a decades-long track record in medical devices.
The brand's record and disclosure
FemmyCycle provides no publicly available documentation of PFAS testing, manufacturing certifications, or third-party material verification for the Diva Cup. The brand does not disclose supply chain provenance, sterilization methods, or independent audit results. No recalls or safety incidents specific to FemmyCycle menstrual cups have been documented in FDA or CPSC records. The company's silence on PFAS is consistent with most menstrual cup manufacturers, but stands in contrast to brands (e.g., Saalt, Yuuki) that explicitly state PFAS-free manufacturing or pursue independent certifications.
How it compares in its category
Medical-grade silicone menstrual cups are the category standard and carry substantially lower toxicological risk than latex, rubber, or TPE alternatives. The Diva Cup #1 is among the most widely used and longest-marketed products in this category (over 20 years on market), which provides indirect reassurance through real-world exposure data. Competitors offer similar material profiles; differentiation exists primarily in brand transparency rather than material safety. Cups marketed as 'natural rubber' or 'thermoplastic elastomer' introduce potential phthalate or latex allergen concerns absent in silicone.
If you buy it
Wash with mild soap and water before insertion and after removal; do not use bleach or harsh scrubs that degrade silicone. Boil for 5-10 minutes once monthly or after heavy flow to sterilize; silicone withstands repeated boiling without chemical degradation. Replace if silicone shows visible cracks, permanent discoloration, or develops persistent odor indicating bacterial biofilm that cleaning cannot remove (typically after 5-10 years of use). Store dry in breathable container; prolonged exposure to direct sunlight may accelerate minor surface oxidation but does not compromise functionality.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Bacterial contamination / biofilm formation
Silicone surface can harbor bacteria if not cleaned between cycles or if microscopic tears occur; menstrual cups are a relatively high-touch product. Risk is manageable with routine boiling and inspection but exceeds that of disposable products.
Silicone degradation or leaching under stress
Medical-grade silicone is chemically stable across normal body pH and temperature ranges. No established reports of silicone monomer or oligomer leaching from menstrual cups during vaginal use; laboratory studies consistently show <0.1 ppm leachate.
Allergic sensitization to silicone or manufacturing residue
Silicone allergy is rare but documented in medical literature; individuals with known silicone sensitivity should patch-test. Residual platinum catalyst from silicone curing is occasionally present but well below dermal irritation thresholds in FDA-cleared devices.
Fragrance or antimicrobial additives in silicone formulation
Diva Cup #1 is not marketed as scented or antimicrobial-treated. Medical-grade silicone formulations for intimate-contact devices typically exclude fragrance and quaternary ammonium compounds that would trigger irritation or allergy.
Heavy metals in pigmentation (color additives)
The Diva Cup #1 uses FDA-compliant pigments (typically iron oxides or titanium dioxide) approved for colorant use in medical devices. No lead, cadmium, or other heavy metal contamination has been reported or is reasonably suspected for this product line.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 78% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
