FemmyCycle · Menstrual Cups
Safe menstrual cup | Size S | Antibacterial | Purple
Lower PFAS concern, silicone cups lack typical vectors, but brand discloses nothing.
FemmyCycle's menstrual cup is medical-grade silicone, a material category with no established PFAS contamination pathway. The antibacterial claim and purple color lack detail, but standard silicone formulations don't require Teflon-type coating coatings or water-repellent treatments.

The full breakdown
What it's made of and why it matters
FemmyCycle Size S is constructed from medical-grade silicone, a synthetic elastomer that does not contain BPA, phthalates, or latex. Medical-grade silicone is inert at body temperature and resistant to degradation during menstrual use (typically 12 hours per cycle). Unlike some lower-cost menstrual cups made from thermoplastic rubber or unspecified elastomers, silicone does not leach plasticizers or monomers into vaginal tissue under normal conditions. The purple dye is incorporated into the silicone matrix rather than applied as a surface coating, reducing migration risk.
The brand's record and disclosure
FemmyCycle provides minimal public disclosure on material sourcing, manufacturing standards, or third-party testing. The brand claims medical-grade silicone compliance but does not publish certificates or identify the specific silicone supplier. No product recalls, contamination incidents, or safety complaints appear in publicly available records for this model. The brand's silence on PFAS, heavy metals testing, or manufacturing facility standards is typical of smaller menstrual cup makers but limits independent verification of quality control.
How it compares in its category
Menstrual cups occupy a safer category than hormonal birth control or absorbent products because the contact surface is internal silicone rather than porous material that can harbor bacteria or retain chemical residues. FemmyCycle's medical-grade silicone sits in the middle tier: more transparent brands (Saalt, Lunette) publish third-party biocompatibility data and FDA clearance documentation, while budget alternatives may use unclear elastomer blends. Size S is appropriate for users with low cervical position or those who have never given birth; incorrect sizing poses fit failure rather than chemical hazard.
If you buy it
Sterilize in boiling water for 5-10 minutes before first use and after each cycle to prevent bacterial colonization. Inspect the cup weekly for cracks, discoloration, or odor; replace if silicone shows permanent deformation or sticky residue. Do not use lubricants containing petroleum products, which can degrade silicone; water or silicone-safe lubricant only. Store in a breathable cotton pouch (not sealed plastic) between cycles to prevent mold growth. Medical-grade silicone cups typically last 5-10 years if properly maintained.
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 overgrowth from inadequate sterilization
Silicone cups rely entirely on user cleaning and sterilization; if boiled water sterilization is skipped or cup stored in sealed containers, bacterial biofilm can develop in microscopic cup ridges. This is a usage hazard, not a material defect.
Incorrect sizing leading to leakage and secondary vulvovaginal irritation
FemmyCycle Size S is not suitable for all users; misfit increases risk of spillage and skin contact with menstrual fluid, not a chemical hazard but a functional safety concern. Brand provides limited sizing guidance online.
Heavy metals in silicone pigments
No testing data or recalls indicate lead, cadmium, or antimony in FemmyCycle silicone or purple colorant. Medical-grade silicone specifications generally exclude heavy metal pigments, but the brand does not publish test reports to confirm this.
Silicone degradation from oxidative stress or heat exposure
Medical-grade silicone is thermally stable to 150-200°C and resistant to oxidation in normal storage; boiling water sterilization does not degrade it. No field reports of silicone breakdown in FemmyCycle cups exist, though long-term wear (5+ years) may produce microscopic cracks.
Allergic contact dermatitis from fragrance or additives in dyed silicone
Silicone itself does not off-gas volatile organics. The purple dye is bonded into the polymer matrix, not surface-applied. No documented allergic reactions specific to FemmyCycle purple cups are on record, though users with silicone sensitivity (rare) may experience vulvovaginal irritation.
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.
