Lena Sensitive Menstrual Cup
Lower-concern product, medical-grade silicone isn't a known PFAS vector, but brand offers no transparency.
This Lena silicone cup isn't typically associated with PFAS contamination. The brand doesn't disclose PFAS testing or make claims about the topic. No third-party verification or lab data exists publicly. Silicone's natural properties reduce PFAS likelihood.

Lab data
No public lab test
What’s concerning
Category baseline
PFAS exposure happens more often with clothing products.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Bacterial or mold colonization
Like all reusable menstrual cups, Lena Sensitive can harbor bacteria or mold if stored wet, in sealed containers, or if internal ridges are not cleaned thoroughly. This is a maintenance issue rather than a material defect; proper drying and breathable storage eliminate the risk.
Allergic contact dermatitis or sensitization
Medical-grade silicone is hypoallergenic for most users, but rare individuals report contact irritation. This is user-specific and not a product-wide hazard; if irritation occurs, switching to a latex-free alternative (not latex, which carries its own allergenic risk) is advised.
Incomplete sterilization if boiled improperly
Rapid boiling or incomplete submersion may leave bacteria in cup ridges; however, proper 5-minute full submersion boil or household dishwasher cycles are sufficient for reusable menstrual cup hygiene. This is a user-execution risk, not an inherent product flaw.
What’s reassuring
Safe base material
Made from ceramic, mineral, or natural fiber with no PFAS risk.
Silicone degradation and leaching
Medical-grade silicone is chemically stable and does not release monomers or plasticizers under normal vaginal pH and temperature. No literature or recalls document leaching from Lena Sensitive or comparable medical-grade menstrual cups.
Heavy metals
Lena Sensitive is opaque silicone without disclosed dyes or pigments; colored menstrual cups have occasionally raised concerns about azo dyes or cadmium in colorants, but Lena's standard versions carry no public record of testing or controversy on this front.

What it's made of and why it matters
Lena Sensitive is constructed from medical-grade silicone, a high-purity elastomer formulated for biocompatibility and minimal reactivity with body fluids. Unlike lower-grade silicone or alternative polymers (rubber, thermoplastic elastomer), medical-grade silicone does not contain plasticizers like phthalates or BPA to maintain flexibility. The body composition is the primary contact surface; Lena does not disclose any coatings, dyes, or additives that would introduce leaching pathways.
The brand's record and disclosure
Lena (owned by Femtech company Lena Inc.) does not publish third-party certification (FDA clearance, CE marking, or independent toxicology reports) on its public-facing materials, though medical-grade silicone products in this category typically meet FDA or European medical device standards. The brand has not publicly addressed PFAS exposure or committed to transparency testing. No recalls or safety controversies are on record for this product line as of public databases.
How it compares in its category
Menstrual cups in this price and material tier (Lena Sensitive, Lunette, DivaCup silicone variants) all use similar medical-grade silicone; differentiation is in ergonomics, firmness, and design rather than chemical safety. Cheaper alternatives using lower-grade silicone or thermoplastic elastomers present higher residual monomer and plasticizer leaching risks. Lena Sensitive's smaller, softer design targets comfort rather than addressing chemical exposure.
If you buy it
Rinse thoroughly before first use and after each cycle; avoid prolonged boiling (over 5 minutes) which can degrade silicone over years of use, though acute sterilization by boiling is safe. Store in a breathable container to prevent mold or bacterial biofilm in humid conditions. Replace every 5-10 years or if the cup shows visible tears, permanent staining, or odor that cleaning does not resolve. Do not use with oil-based lubricants or in extreme heat environments.
