Menstrual cups: 2 products tested

How we did the test

Our tests are independently conducted and reflect the test editor's honest and objective opinions. Selection of products and test results are in no way influenced by manufacturers, retailers or other internal or external parties.

We carry out our tests ourselves and test all products as they are intended to be used in reality. In this test, for women between 25 and 40 years of age used the menstrual cups. Each menstrual cup was used for several cycles and in accordance with the manufacturer’s instructions. Some of the women had given birth vaginally, some only by caesarean section, and one woman was under 30 and had not given birth. All of the women used the manufacturer’s recommended size of menstrual cup, but we also asked some of them to test the other sizes to get an idea of how much the sizes vary. In our test of menstrual cups, we focused on the following aspects:

  • Use: What’s it like to insert the cup, is it easy to get in the right position and is the protruding stem comfortable and easy to get hold of?

  • Cleaning: Is the menstrual cup easy to rinse out and keep clean, and has it stayed fresh even after six months’ use?

  • Design and accessories: What does the cup look like, how good were the instructions and how well did the storage bag work?

The testers’ impressions and opinions on the different models of menstrual cup were then compiled and formed the basis for our assessment and score.

We tested a selection of menstrual cups. Compare prices for the most popular menstrual cups on PriceRunner.

1. Lunette

Model: Cynthia Colour: Purple Material: Medical silicon Sizes: Two – Model 1 and Model 2 Accessories: Storage bag (included) and disinfectant wipe (bought separately)

Lunette Menstrual Cup Model 1

Lunette’s Cynthia is a purple menstrual cup in medical silicon that comes in two different sizes. Model 1 has a diameter between 41 and 47 mm and a volume of 25 ml. Model 2 has a slightly larger volume of 30 ml, and a diameter of 46 to 52 mm. Both have a flat, ribbed stem. The stem on the smaller model is 25 mm long, while Model 2 has a shorter stem of 20 mm.

Sturdy and easy to get in the right place

According to Lunette, you should largely base your choice of size on the quantity of blood. Model 1 has also been made of softer silicone to make it easier to insert. Our testers agreed that Model 2 of the Lunette Cynthia was the stiffest menstrual cup in the test, which made it feel sturdier and relatively easy to get into the right position. It also made it a bit easier to feel whether or not the menstrual cup had unfolded completely.

Easy to grip stem

The testers who hadn’t trimmed off the stem of the menstrual cups found Cynthia’s flat, ribbed stem to be their favourite. It’s easy to get hold of, even when wet and slippery. The purple colour was popular but made it slightly more difficult to see through the cup and check whether or not there was still blood in the small air holes in the upper edge of the menstrual cup. There are lines on the outside of the cup, but no information about what quantity of blood these represent.

Nice storage bag

The storage bag that comes with the Lunette Cynthia isn’t merely the most decorative one – the material and colour also mean it resists dirt and looks more like it belongs in your handbag. The instructions were clear and contained a number of useful beginners’ tips for how to get started with menstrual cups. With their Cynthia menstrual cup, Lunette have succeeded admirably in producing an attractive and user-friendly design.

2. Belladott

Model: Evelina Colour: Blue Material: Silicon Sizes: Two – Small & Medium and Large & Plus Accessories: Storage bag (included) and Belladott Cleansing Gel (bought separately)

Belladot Evelina Menstrual Cup Large/Plus

The Belladott Evelina is a menstrual cup manufactured of safe silicon that doesn’t affect the vaginal pH balance. The Evelina is available in two sizes, Small & Medium with a volume of 25 ml and Large & Plus, which can hold 30 ml of liquid. The Evelina has a narrow, rounded stem with a knob at the end. Belladott’s recommendation is that you should choose the smaller size if you haven’t given birth and are under 30 years of age, and the larger one if you are over 30 or have given birth.

Soft and flexible menstrual cup

The Belladott Evelina is made from soft and flexible material, and often gave the best first impression to testers. It was also a favourite with those women who hadn’t given birth. The blue colour is appealing and more translucent than some other menstrual cups, making it easy to see how much blood is in the cup. On the outside, the Evelina is also marked with a clear scale, which is useful if you want to keep track of your flow. The instruction book has good images, but we’d have preferred to see more information about how the cup should be emptied and for there to be a mention of toxic shock syndrome. It also mainly contained facts rather than useful tips. Cleaning and disinfecting the cup were perceived as straightforward, and the light colour made it easy to see if any blood remained in the small holes at the top of the menstrual cup.

Not a great storage bag

The storage bag that comes with the cup is an odd, long shape which means the menstrual cup easily gets lost at the bottom. It’s also white, which means it quickly gets dirty if it’s in your handbag. The stem is less user-friendly, but if you prefer not to trim the stem this neat design means it doesn’t chafe so much. The Evelina benefits from being soft and therefore easy to fold up. Consequently, some of our testers found the Belladott Evelina to be particularly comfortable, and the low price also makes it very good value for money.

All about menstrual cups

A menstrual cup is an alternative form of menstrual protection, which unlike towels or tampons can be used over and over again. This means that menstrual cups are kinder both on the environment and, over the longer term, on your purse. A menstrual cup can be made from plastic or silicon. It’s bell-shaped or, as the name indicates, cup-shaped, and has a protruding stem at the bottom. The stem makes it easier to get hold of the cup to remove it. If you feel the stem is in the way or too long, you can trim it to the right length. You use a menstrual cup by folding it up and inserting it into the vagina. Once in place, the menstrual cup unfolds and captures the menstrual flow. A menstrual cup can remain in the vagina for up to 12 hours and can be used while you're sleeping, swimming or exercising.

Most menstrual cups are available in two different sizes. The size intended for a particular target group varies slightly between the different manufacturers, but in general the smaller size is intended for women under the age of 30 and who haven’t given birth and/or for those who have a lighter flow. The larger size is intended for women over 30 or who have had children, and for those with a heavier flow. The fact that the size you should choose is partially related to age is because the musculature inside your vagina can be affected by your age. You can start using a menstrual cup right from your first period, provided you're comfortable inserting it into the vagina and are able to get it into the right position.

Before you first use a menstrual cup and before each new menstrual cycle, you must disinfect the menstrual cup by placing it in boiling water for a certain length of time. During your period, you can simply rinse it out with water each time you empty it. Some people also choose to wash their menstrual cup out with soap. If you do this, it’s very important to make sure that no soap residues remain as this can irritate the mucous membranes inside the vagina.

Why choose a menstrual cup?

Apart from the major advantages that a menstrual cup means a reduction in waste impacting the environment and that it quickly pays for itself compared to traditional menstrual protection, our testers have also discovered several other advantages of menstrual cups. A menstrual cup can be used for a longer time, which means you don’t have to change your menstrual protection every time you go to the loo. This is particularly practical when you're out on the town or in public spaces, or you're using a toilet where there’s no washbasin or soap. Those of our testers who were on the road or trying out the menstrual cup during their summer holidays found it to be ideal for use on the beach or in less hygienic airports. Several testers also felt that a tampon seemed to “plug” the menstrual flow, while a menstrual cup allowed the body to release the menstrual blood as intended. This felt fresher and more healthy. Our testers also found that menstrual cups stayed in place very well during tough exercise – in fact even better than a tampon, which tend to slide downwards as they fill up with blood and become heavier.

Why not choose a menstrual cup?

Our testers’ primary objection to a menstrual cup was that it can be difficult to get it into the right position in the vagina so it seals completely. Nor did they all agree that practice makes perfect and that the problem reduced over time. On some occasions a few drops of blood found their way past the menstrual cup and our testers felt it necessary to use a panty liner for extra protection. The process of disinfecting the menstrual cup between uses also requires a certain amount of preparation. However, all of our testers felt it was worth spending this time given the many advantages of using a menstrual cup. Half of the testers said they would never go back to normal menstrual protection, while the other half said they will continue using menstrual cups and supplementing them with occasional towels or tampons.

Our testers’ top tips!

  • Our testers found it difficult to get the menstrual cup to unfold completely, particularly the first few times they used one. One tip is to run a finger around the upper edge of the cup to make sure it isn’t folded in. Another is to gently rotate the cup after inserting it. Several testers found this to be the most effective method.

  • A menstrual cup shouldn’t be inserted as far as a tampon. There’s a risk that it will end up beside or behind the cervix, which means it can’t capture the menstrual blood as it flows out. The trick is to insert it low down so it covers the entire vaginal opening, but not so low that you can feel it.

  • Menstrual cups work by making a seal. When you remove the menstrual cup, don’t just pull on the stem, as this can be painful. To release the seal first, you can either insert a finger and press the upper edge of the cup to create an air pocket. Or you can pinch the bottom of the cup with two fingers so the opening of the menstrual cup changes shape and releases its hold on the vaginal walls.

  • And if you think it's difficult to choose the right size, relax. It turns out that our testers didn’t feel there was much of a difference between the sizes. We asked a younger woman who hadn’t given birth to try out both sizes of a single menstrual cup, and she couldn’t tell the difference between them. But nor did she feel that the larger one was more effective at dealing with leakage than the smaller cup.
