Medical‑grade silicone is the gold standard — it's soft, flexible, and hypoallergenic. Latex is natural rubber — it's biodegradable but can cause allergies. The menstrual cup market forecast shows that silicone holds 68% market share, but latex is the fastest‑growing. Why the shift? Because some women want a plastic‑free option, and latex cups are compostable.

What's the difference in feel? Silicone is more pliable and tends to seal better. Latex is stiffer and may be less comfortable for some. The menstrual cup market analysis notes that the fastest‑growing distribution channel is online, where women can read reviews and compare materials before buying.

But latex allergies are common — up to 6% of the population. If you have a latex allergy (or a sensitivity), stick with silicone.

The bottom line: silicone is safe for almost everyone. Latex is a niche option for the allergy‑free and eco‑conscious. Choose wisely.
