Did you know that the menstrual disc and the menstrual cup don’t compete for the same thing, even though they look like close cousins? One sits in the vaginal fornix, the other seals by suction below the cervix, and that single difference in position changes almost everything: comfort, period sex, the learning curve and even the size you need. Let’s compare menstrual disc vs cup<\/strong> honestly, without forcing the answer toward what we sell.<\/p>\n

Menstrual disc or cup: the difference that explains everything<\/h2>\n

The menstrual cup works by suction: when it opens inside the vagina it creates a vacuum seal that stops it moving or leaking, and it sits just below the cervix. The menstrual disc, on the other hand, doesn’t suck anything: it’s held by its own shape, tucked into the vaginal fornix (the deepest space, around the cervix), resting behind the pubic bone. You can go deeper into these mechanics in our complete guide to what the menstrual disc is and how it works<\/a>, where we explain with full transparency that Sileu doesn’t sell discs \u2014 so this comparison isn’t biased toward a product we make.<\/p>\n

That difference in position is the root of almost all the pros and cons of each product: who can have sex with the disc in, why the disc has a shorter learning curve for removal but a longer one for insertion, and why the cup requires finding your exact size while many discs are “one size”.<\/p>\n

If you choose the cup: Sileu Classic \u2014 \u20ac14.99<\/strong><\/p>\n

The most versatile cup in the range, with medium flexibility, suitable for most bodies and flows. Medical-grade silicone certified to ISO 10993. Shipped from Spain in 24-72h.<\/p>\n

Where each product sits (and why it matters)<\/h2>\n

This single anatomical detail explains why so many people ask “menstrual disc or cup?” thinking they’re interchangeable, when in fact they meet different needs. If your priority is having sex during your period without removing the product, the disc has the edge because it sits above the area of penetration. If your priority is a complete seal and maximum protection against leaks for many hours, the cup’s suction usually wins.<\/p>\n

Which to choose for your anatomy: high cervix, low cervix and size<\/h2>\n

Sileu Tulip (slim) and Sileu Classic (all-rounder), two of the cups most often compared with the disc.<\/figcaption><\/figure>\n

If you have a low cervix<\/strong> (less than 6 cm from the entrance), a standard cup may stick out and feel uncomfortable; that’s where the Sileu Bell<\/a> comes in, with a body of just 30-35 mm designed for that anatomy, which usually solves the problem without having to turn to a disc. If you have a high or mid cervix<\/strong> and no particular reason for a disc (such as period sex), the Sileu Classic<\/a> is the default option: medium flexibility, good capacity and the easiest to learn. And if you prefer a slim cup that folds small, the Sileu Tulip<\/a> is the most streamlined in the range.<\/p>\n

To find out whether your cervix is high or low, and to choose a model and size with real data instead of guessing, we have a dedicated guide: how to locate your cervix and choose your model and size<\/a>.

Low cervix? Sileu Bell \u2014 \u20ac14.99<\/strong><\/p>\n

The shortest cup in our range, with a bell-shaped body designed for a low cervix, so you don’t need to turn to a disc. Medical-grade silicone certified to ISO 10993.<\/p>\n

The menstrual disc and the menstrual cup meet different needs; they aren’t 100% interchangeable.<\/figcaption><\/figure>\n

Period sex: the most cited argument for the disc<\/h2>\n

It’s the number-one reason people switch to the disc: because it sits above the area of penetration, many couples can have vaginal sex during a period without removing it (although it isn’t 100% guaranteed; it depends on each person’s anatomy). With the cup, that isn’t possible: you have to take it out first. If this is your top priority, the disc has a real advantage we won’t deny just because we don’t sell it. You can read more in our article on sex on your period and mess-free options<\/a>, where we go over alternatives \u2014including the cup and other options\u2014 for each case.<\/p>\n

If period sex isn’t your main priority, the balance usually tips toward the cup: it seals better, it’s reusable in the vast majority of models (many discs are disposable), and the overall learning curve \u2014counting insertion and removal\u2014 is usually shorter.<\/p>\n

Is the menstrual cup safe? What the evidence says<\/h2>\n

Both reusable cups and reusable discs are made of medical-grade silicone, designed for prolonged intimate use. In the case of the cup, the scientific evidence is solid: the systematic review in The Lancet Public Health (2019)<\/a>, with 43 studies and more than 3,300 participants, concludes that the menstrual cup is a safe option, with leakage equal to or lower than tampons and pads. For questions about symptoms related to menstrual products, always consult reliable sources such as MedlinePlus<\/a> or your gynecologist.<\/p>\n

Maintenance and lifespan: reusable doesn’t always mean the same thing<\/h2>\n

Here’s another nuance that gets lost in many quick comparisons: not all menstrual discs are reusable. There are disposable versions (designed for a single cycle or even a single use) and reusable silicone versions, which are washed just like a cup. If your goal is to reduce waste, make sure you buy the reusable version \u2014 otherwise you’ll be swapping one disposable for another, even if it holds more. Menstrual cups, by contrast, are reusable by design in practically 100% of the market.<\/p>\n

For daily cleaning, both products are rinsed with water between uses and sterilized at the end of the cycle (boiling water, a sterilizer or specific tablets). If you choose a cup, our guide on how to sterilize a menstrual cup<\/a> answers the typical questions. The cleaning routine is practically identical between a reusable silicone disc and a cup, so this point shouldn’t sway your decision.<\/p>\n

So: disc or cup?<\/h2>\n

Choose the disc if<\/strong>: you want to have penetrative sex during your period without interruptions, or a standard cup is uncomfortable because of a very low cervix and you haven’t yet tried a model designed for it, such as the Bell.<\/p>\n

Choose the cup if<\/strong>: you prioritize a complete, leak-free seal, want a product you can reuse for years at no extra cost, or prefer to start with something with a shorter learning curve and plenty of documentation available. If you’re unsure where to start, our guide to choosing your first menstrual cup<\/a> walks you through it step by step, and the comparison of the seven Sileu models<\/a> helps you narrow down which one fits your anatomy.<\/p>\n

What’s the difference between a menstrual disc and a menstrual cup?<\/h3>\n
\n\n

The menstrual cup sits below the cervix and seals by suction; the menstrual disc sits in the vaginal fornix, next to the cervix, and is held only by its shape, with no suction. That difference in position explains almost all their pros and cons.<\/p>\n\n<\/div>\n<\/div>\n

\n

Can you have sex with a menstrual disc in?<\/h3>\n
\n\n

In many cases yes, because it sits above the area of penetration, unlike the menstrual cup, which must be removed before sex. It isn’t 100% guaranteed for every anatomy.<\/p>\n\n<\/div>\n<\/div>\n

\n

Which menstrual cup is best for a low cervix, as an alternative to a disc?<\/h3>\n
\n\n

The Sileu Bell, our shortest cup, with a body of just 30-35 mm designed specifically for a low cervix, usually solves the discomfort a standard cup causes without having to turn to a menstrual disc.<\/p>\n\n<\/div>\n<\/div>\n

\n

Is it harder to learn to use a menstrual disc than a menstrual cup?<\/h3>\n
\n\n

Inserting a disc usually has a somewhat steeper learning curve at first, while removing a cup (once you’ve mastered the pinch-and-release technique) tends to feel more intuitive for most users.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>
