Menstrual Cup vs. Menstrual Disc: The Difference Simply Explained

Choosing the right menstrual product can be a real challenge. Perhaps you're asking yourself right now: what exactly is the difference between a menstrual cup and a menstrual disc? Both options offer an eco-friendly way to manage your period, but they differ fundamentally in shape and handling. In this article, you'll learn everything you need to know to make the perfect choice for your body. ✨

A menstrual cup is a reusable product for your menstruation, usually made of high-quality material such as medical-grade silicone. Unlike tampons, which absorb blood, the cup collects the fluid inside your body. But how does it stay in place? The secret lies in physics: when the folded cup is inserted into the vagina, it unfolds and creates a slight vacuum against the vaginal wall.

This vacuum seals the area completely so that no blood can pass. According to expert advice from Swissmom, this suction effect is crucial for the reliability of the menstrual cup. You can imagine it as a small, flexible chalice that sits securely in the lower part of the vaginal canal. When you want to remove it, you simply release the vacuum by gently squeezing the lower part of the cup. This makes removal much easier. Some models are even available in black, which has the advantage that the material does not visibly discolour over the years.

The menstrual disc (often called a menstrual disc or in English menstrual disc) is an innovative alternative to the classic cup. Visually, this disc resembles a flat bowl with a flexible, slightly firmer rim. The biggest difference lies in placement: while the cup sits in the lower vaginal canal, the menstrual disc is pushed much deeper into the body.

More specifically, it is placed in the vaginal fornix and anchored directly behind the pubic bone. The Department of Health in New Jersey (NJ Health) describes this positioning as a crucial advantage, as the disc covers the entire cervix there and collects blood directly at the source. Since it is supported behind the pubic bone, it does not require a vacuum to hold it securely. It essentially clamps itself naturally. This makes it particularly interesting for women who have problems with the vacuum sensation of a cup. In international forums, you often read the advice: "The best option for you and your body is not always the first one you try, so continue testing." And that's exactly what applies here!

Let's directly compare the two products in the most important categories so you can choose the best option for you. 🔍

Menstrual discs are usually made of extremely flexible medical-grade silicone or special plastics such as polyethylene, which makes them particularly adaptable. Menstrual cups, on the other hand, are cup-shaped and often have a small stem or ring at the bottom, which helps with gripping. As mentioned, cups sit significantly lower in the vaginal canal than discs, which fundamentally distinguishes their placement.

The way these products seal could not be more different. Cups seal by vacuum; they suction to the walls of the vagina. Discs, on the other hand, sit purely mechanically. They are held in place by your own anatomy, which many users find very comfortable.

If you have a heavy flow, capacity is an important criterion. A clinical study on PubMed shows that menstrual discs have the largest capacity of all menstrual products, averaging 61 ml. In comparison, menstrual cups have a capacity of approximately 20 to 50 ml according to lab tests, depending on which of the various sizes you choose.

Every beginning is difficult, we all know that! Studies show that between 10 and 45% of users initially report difficulties with insertion or removal. It usually takes 2 to 3 cycles to get the hang of it. Most importantly: remember to always wash your hands thoroughly with soap and water before insertion and removal to avoid infections, as Swissmom also emphasizes.

A huge plus point of the disc: it allows for uncomplicated sex during your period (period sex). Since the menstrual disc, due to its high position in the vaginal fornix, leaves the vaginal canal completely free, neither you nor your partner will feel it when used during sex. If you want to fully enjoy your intimate life even during menstruation, Loveiu offers not only suitable water-based lubricants but also the necessary inspiration for sensual hours. The disc makes it possible, without anything leaking. 💦

After your cycle, menstrual cups and reusable discs must be sterilized by boiling them in bubbling water for one to two minutes, as recommended by the FDA. However, be warned not to clean cups in the dishwasher or treat them with aggressive disinfectants, as this destroys the material. For gentle and hygienic cleaning, there are special cleaning products.

To make the comparison between menstrual cup and menstrual disc even easier for you, here is a clear table:

The decision heavily depends on your individual needs. If you have a very heavy flow and intimacy is important to you, the disc is often the better option. Its large capacity and mechanical fit offer clear advantages here. If, however, you prefer a product with a noticeable vacuum hold, you will be happier with the classic cup.

Many teens and adult women also like to combine these products with period panties as an additional backup on heavy days. It's best to read a few reviews and, if in doubt, simply try both variants to find out what you feel most comfortable with in everyday life. 🌸

Regardless of whether you ultimately choose the cup or the disc, both options are a fantastic step towards a more sustainable period. They not only protect the environment but, in the long run, also your wallet. The difference between a menstrual cup and a menstrual disc primarily lies in placement and the type of seal.

Give yourself and your body some time for the learning curve. It's completely normal for it to take a few cycles for everything to become routine. With the right technique and positive experiences, you'll soon not want to do without these comfortable alternatives to conventional pads.
