Menstrual cup
Reusable bell-shaped device that collects menstrual fluid internally.
A menstrual cup is a reusable menstrual hygiene device inserted into the vagina to collect menstrual fluid. Made from elastomers such as silicone, latex, or thermoplastic rubber, it is bell-shaped with walls over 2 mm thick and seals against the vaginal walls to prevent leakage. Menstrual cups are a safe alternative to tampons and pads, with similar or lower risk of toxic shock syndrome, and generate less solid waste due to reusability.

Lore & Background
Menstrual cups are inserted into the vagina after folding, then expand to form a seal. They sit in the vaginal canal, with the rim generally in the vaginal fornix. Users may initially find insertion difficult, uncomfortable, or painful, but this typically improves within 3–4 months. The cup does not obstruct the vaginal canal like discs, and it remains in place through suction, which must be broken for removal. Cups are available in various sizes and firmness levels to accommodate different anatomies.
Reader's Guide
Menstrual cups offer a long-term, low-waste alternative to disposable tampons and pads. Their initial cost is higher, but one cup can be reused for up to 10 years, reducing solid waste from both the product and its packaging. They allow users to sleep, swim, exercise, and engage in physical activities without leakage when properly fitted. However, incorrect placement or size can cause leakage, and users must wash the cup and hands thoroughly to avoid introducing bacteria. The learning curve for insertion and removal can be steep, but many users adapt within a few cycles. Menstrual discs, a related product, sit higher in the vaginal fornix and do not create suction, allowing for hands-free emptying and use during penetrative sex.

Frequently Asked Questions
What is a Menstrual cup?
A menstrual cup is a reusable, bell-shaped hygiene device crafted from flexible elastomers such as silicone, latex, or thermoplastic rubber. It sits inside the vagina and gathers menstrual fluid rather than soaking it up like a tampon or pad.
What are Menstrual cup's powers/role?
The cup creates a seal against the vaginal walls and holds fluid internally, typically needing to be emptied only every four to twelve hours. This gives users a lower-waste, cost-effective option while carrying a similar or even reduced risk of toxic shock syndrome compared to disposables.
How does Menstrual cup's story end?
A single cup can remain in service for roughly ten years before its material begins to degrade and it must be retired. At that point the user simply discards the old unit and replaces it with a fresh one.
Why is Menstrual cup important?
Because one cup can last a decade, it eliminates the recurring solid waste that disposable pads and tampons generate over a person's lifetime. It also offers a comfortable, economical option that many find more convenient than swapping disposables several times a day.
What are Menstrual cup's known limitations?
The device requires a learning curve to insert, remove, and clean properly, and users with silicone or latex allergies must select a compatible material. It is also less forgiving during very heavy flows unless the user empties it more often than the standard four-to-twelve-hour window.
