Most frequently asked questions about menstrual cups

Which sizes are available and which of them should I order?

Yuuki offers two sizes. One for women who have already given birth and one for women under 28 years of age who have not yet given birth. The Yuuki cups come in two sizes: No. 1 - small and No. 2 - big. The difference between the small and big cups is one of the biggest differences among those offered by cup manufacturers.

You can find the sizes on our blog .

It seems very big! Is it painful to insert and remove?

If you do it correctly and carefully, it should not be painful. Women who have not yet had sexual intercourse may have some problems at the beginning, but they will pass with time. The vagina is able to stretch to allow a baby’s head to pass through it, and the cup is many times smaller. When inserting the cup, you can lubricate it with water or with lubricating gel. When inserting the cup, press its bottom to release the vacuum and take it out carefully.

What is the useful life of the cup?

Most manufacturers state ten years. Theoretically, it can last till the end of one’s life because it is made of the same type of silicone as that implanted during surgery. It is up to you whether to purchase a new cup. We provide a two-year warranty on the Yuuki cup.

Can the cup leak?

No, not if it has been inserted correctly and is emptied before it gets completely full. After inserting the cup, you need to turn it slightly and pull it a bit, to create a vacuum to make the cup stick to the vagina wall.

How often do I have to empty the cup?

It depends on your period. The intensity of every woman’s menstrual flow varies. If your menstruation is average to heavy, you should empty the cup every 3 to 10 hours. Some women with very low menstruation may even go 12 hours before emptying the cup.

On heavier menstruation days, you may have to empty your cup more often. If you have tried already the big cup and have seen that you have to empty it every three hours, you have an extremely heavy period. That need not be a problem but you should discuss it with your doctor. There are means of controlling such heavy menstruation.

Can I feel the cup when using it?

Most women do not feel it, particularly if they have cut away the cup stem. Some are aware of having the cup, like having a tampon. The cup is soft, and when you have the right size and type and it is correctly inserted, you should not feel any pain or discomfort.

How can I see that the cup is in the correct position and fits tightly?

Never insert the cup right up. The vagina is angled toward the rectum, so incline the cup in that direction. To check whether it fits tightly, grasp the stem and try to turn the cup or run your finger over the rim to check that it is oval in shape.

If you are able to turn the cup, it does not fit tightly. Try to move it carefully up and down. A little air should enter to seal the cup.

Do I have to sterilize my cup?

It is recommended. You should of course wash the cup daily with warm water or with disinfection water. In any case, the cup must be boiled for 5-10 minutes each time before starting to menstruate or you should use our IB - infuser box.

How to sterilize the cup?

It might happen that you’ll be somewhere where you can’t boil the cup in a normal saucepan. In this case we recommend using our sterilization box, which is used to store the cup during your menstrual cycle and also to sterilize the cup in a microwave. We certainly do not recommend using any chemicals (Savo, peroxide).

We have soap gel at work. Can I use it to wash the cup?

It is important that it has neutral pH (unfortunately we do not recommend classic soap gel, but if it has neutral pH, then you can use it).

It doesn’t matter, however; if you’re not sure, just wash the cup with clean water and then clean it properly when you get home (you can also moisten a paper towel and use it to wipe the cup).

How can I clean the cup in public rest rooms?

You take it out and clean in the same way as at home, but you should take a bottle of water, our disinfection water or a wet paper tissue with you to clean the cup before using it again. You can clean the cup thoroughly when you get back home.

Can a girl who has not yet had sexual intercourse use the cup?

That is completely up to you. The cup will change the hymen. So, if you (or your family or religion) believe that the hymen must stay intact until the wedding, you should wait until after you have first had sexual intercourse. In all other respects, it is completely all right.

What does toxic shock syndrome mean? And can the cups cause it?

There’s no need to worry; unlike tampons, menstrual cups do not cause TSS.

This dangerous disease is caused by bacteria that multiply inside absorbent materials, such as tampons. If you use them, be careful and do not underestimate the symptoms: severe flu, aching muscles, stomach cramps, head and neck pain, a sudden rise in body temperature above 39 °C, diarrhoea and vomiting, sudden drops in pressure and rapid heartbeat, often accompanied by a feeling of weakness, dizziness, a rash (this may occur on various parts of the body or just in specific places such as the armpit or groin area).

Can the cup get lost or stuck inside me?

No; if you remove the vacuum well, you can take it out easily. The cup is flexible. If you remove enough of the vacuum, you can take the cup out very easily. And it cannot get lost inside you. It is firmly encircled by the vagina muscles, forming a sort of casing in which the cup is "embedded".

I have problems taking the cup out. What should I do?

Most women will have no problems taking the cup out. However, if you do, this means you did not remove the vacuum sealing the cup. First, try to relax as much as possible. If this does not help, try to squat down (which will shorten the vaginal passage) or bend forward, such as when having intestinal problems, to reach the cup better. But if you think you cannot take the cup out without spilling it, go to the shower, press the cup wall completely and take it out. Most women are more concerned with spilling the contents than taking the cup out. Nevertheless, taking it out is the main priority. Different cups each work a little differently, but they always require some experience taking them out.

Can women lend each other the cup after sterilizing it properly?

Surprisingly, this is one thing that women attempt to do in countries with a lower standard of living. But our company discourages it. Particularly if it is not guaranteed that the cup is 100% sterilized. Even when it is cleaned thoroughly, there is a risk, particularly if one of the women has an infection.
