What are the particularities of the Merula Cup?

From weak to strong pelvic floor muscles: The Merula Cup stays where it belongs. As it can be worn in a folded up state and does not have to open completely, even strong pelvic floor muscles do not make it lose its shape.

    Merula Cup „one size“

    • It has a very large capacity (up to 38 ml / 1.285 fl oz). With a diameter from 40 mm to 46 mm / 1.575 in. to 1.811 in. Merula adapts perfectly to your body and is an ideal companion for light to heavy bleeding.
    • Due to its spherical shape, Merula Cup has a short height of only 39 mm / 1.535 in. and an impressive capacity, which is roughly equal to 2 large tampons. Because of that, Merula Cup can easily be used by women with a low cervix. The cup can also be used without any difficulty if you have a high cervix, as it has a long, ladder-shaped stem.
    • Measuring the height of your cervix before using the cup for the first time is not necessary. Simply decide, which length of the stem would be perfect for you. If necessary, you can adapt it by cutting one or two levels from the stem.

    Merula Cup XL

    • It has a very large capacity (up to 50 ml / 1.691 fl oz) with a diameter of 46 mm / 1.811 in.. Merula adapts perfectly to your body and is an ideal companion for very heavy bleeding.
    • The Merula Cup XL offers maximum capacity at a cup height of only 50 mm / 1.969 in., which is roughly equal to 2 average, conventional menstrual cups or 2.5 large tampons. As such, the Merula Cup XL fits women with a medium to high cervix. Thanks to its two rung ladder stem, it can be ideally adapted to your personal needs.
    • The Merula Cup XL is suitable for a medium to high cervix. Should your cervix be exceptionally low or if you feel your vagina is exceptionally “tight”, then the Merula Cup XL may be too large for you. In this case, we recommend the Merula Cup “one size” with a capacity of 38 ml / 1.285 fl oz.

    ABOUT USING IT

    When looking for the right position of your menstrual cup, you should take enough breaks and take your time. A practice phase of 1-4 cycles is not uncommon. However, if, despite your best efforts, you cannot position the Merula Cup in a comfortable and leak free position, do not be afraid to contact us!

    • Can I try out wearing the Merula Cup when I’m not on my period?
      Yes, that’s possible. However, it is often more difficult to wear a menstrual cup outside of your period, as the vaginal wall is then often much firmer and the cervix positioned higher. Thus, experiences while not on your period are not completely transferable to wearing a menstrual cup during your period. So don’t be discouraged if it doesn’t work right away.
    • I can feel a strong pulling sensation / I have lower abdominal pain when I am wearing the Merula Cup. Is that normal?
      No. If the Merula Cup is positioned correctly, it should be practically imperceptible. A menstrual cup should not be uncomfortable or cause pain. If it causes pain, it could be that the cervix is not correctly placed within the Merula Cup or, for example, the ladder is too long and causes irritation at the vagina’s opening. In this case, try to correct the position or adjust the ladder according to the instructions.
    • The Merula Cup is leaking – What am I doing wrong?
      If your Merula Cup is leaking, your cervix is most likely not placed correctly inside the menstrual cup. Try to adjust the cup’s position.
    • How can I insert and position the Merula Cup correctly?
      This is how you can position your Merula Cup correctly: Before inserting it, feel for your cervix and guide your Merula Cup in this direction. Open the menstrual cup’s rim in front of the cervix and then place the cup around the cervix. What can help with placing the cervix into the cup is to move the cup upwards with “screwing” motions, while gently pressing the pelvic floor downwards. If the Merula Cup can be easily turned and at the same time not just pulled out again, it is very likely that it is positioned correctly.
    • Can I have sexual intercourse with the Merula Cup?
      We do not recommend this as there is a risk of injury from vaginal penetration when wearing a menstrual cup. Therefore, the menstrual cup should definitely be removed before penetrative sex. It is, however, ideal for use during oral sex.
    • Can I pull out the Merula Cup by its ladder?
      The Merula Cup must not be pulled out by its ladder before the existing seal has been released. If your Merula Cup is placed very high up, you can carefully move it downwards with “zig-zag” movements so that the body of the cup comes within reach of your finger(s). Now hook a finger into one of the ladder rungs and break the seal by pressing the cup’s body in firmly. The Merula Cup can then be removed easily.
    • Why should the Merula Cup not be worn for more than 8 hours?
      This guideline is based on a French paper published in the USA in 2018 (cf. “Nonfoux et al.”). Although we partly doubt its results and findings, but because consumer protection is our top priority and we want to meet international legal requirements (including those in France and Australia), our recommendations regarding the wearing time (maximum of 8 hours, as with tampons) and cleaning of menstrual cups are the following:
      Careful hygiene and regular cleaning of the menstrual cup are absolutely necessary to minimize the risk of Toxic Shock Syndrome (TSS). A risk of TSS is not excluded when using menstrual cups. Although there are currently only a few cases of TSS in connection with menstrual cups (not with the Merula Cup!) known, in which the actual causality to the use or wearing duration of the menstrual cup could not be established.
    • Can I play sports or go swimming with a menstrual cup?
      Yes. In fact, the Merula Cup is particularly suitable for all types of sports and remains securely in place even when the pelvic floor muscles are contracted repeatedly. It is also the optimal solution in and under water, as no blood can leak out and no water can leak in.
    • Can I use a menstrual cup at night?
      Yes, the Merula Cup stays in place securely overnight. If your Merula Cup is positioned correctly, you can go to sleep worry-free and feel safe, as in all other everyday situations. Please pay attention to the wearing time of your menstrual cup.
    • Can I use the Merula Cup even if I’m wearing an IUD (hormone, copper, coil or ballerine)?
      The use of a menstrual cup with a well-fitting IUD is generally not a problem. The slight seal created by menstrual cups only affects the cervix and not the IUD (inside the uterus) or its thread. You should simply be careful of not accidentally pulling on the IUD’s thread. Additionally, as is generally the case when using menstrual cups, you should make sure to always carefully release the seal before removing the cup.
      It is also important to know that IUDs can be rejected by the body, especially in the first months of wearing, completely independently of the method of menstrual hygiene. Naturally, this process usually takes place during the period. We therefore recommend waiting for the first period after insertion of the respective contraceptive or the first check-up by a gynaecologist before using a menstrual cup again.
    • Can I use a menstrual cup if I have vaginal yeast infection? What should I keep in mind?
      We recommend switching to disposable hygiene products in case you have a vaginal yeast infection. If you’ve had your Merula Cup in use during this time, the menstrual cup should ideally be professionally autoclaved. For home use, there are two options:
      1. Boil your menstrual cup in water (with a splash of vinegar) 3 times for 20 minutes each. Between each boiling process, let it air dry for several hours. Please note that this procedure may stress the material of the cup and therefore shorten its life span.
      2. Put your cup in a 3% hydrogen peroxide solution overnight. However, this procedure may stress the material of the cup and therefore shorten its life span.
    • What is the best way to store my Merula Cup?
      Always store your Merula Cup in an airy container, for example the pouch provided.
    • How long can I use my Merula Cup?
      With optimal care, you can use your Merula Cup for several years. If the menstrual cup shows signs of material fatigue, please dispose of it via the bin for residual waste and buy a new one.
    • Can the hymen break when using a menstrual cup?
      This is possible in principle. However, the hymen can also break during sports for example, or be weakly developed in general. On the other hand, for some people, the hymen remains intact until, for example, a spontaneous birth.
    • Can I use the Merula Cup if I’ve never had sex?
      Yes, that is perfectly fine. Menstrual cups are also suitable for virgins.
      Many teens and people who have not had sexual intercourse yet use the Merula Cup. Its material has a soft touch and glides easily. To make the cup glide even easier, you can moisten it with water or water-based lubricant (such as Merula Lube) beforehand. However, this is not absolutely necessary. You are welcome to discuss this matter with your peers in our “Merula Cup Community” on Facebook.

    ABOUT THE SIZES

    • Why is the Merula Cup a one-size-fits-most menstrual cup?
      The special nature of the Merula Cup ensures that it can fit with high to low cervical positions, as well as any condition of pelvic floor muscles. This saves you the search for the right sized menstrual cup.
    • What is the difference between Merula Cup and Merula Cup XL?
      The Merula Cup is available in two different sizes: “one size” and XL (extra large capacity for very heavy bleading, e.g. if you have to change a Super Plus tampon every hour).
      The Merula Cup “one size” was developed in one size so it can fit most menstruators. It has a fairly large capacity of 38 ml / 1.285 fl oz. Its long, comfortable ladder can be shortened (by one or two rungs) to your individual comfort length. The cup’s spherical body adapts to each individual anatomy.
      The Merula Cup XL was developed for particularly heavy bleeding. With a capacity of 50 ml / 1.691 fl oz, it is one of the largest menstrual cups on the market. Its ladder can be adjusted (by one rung) to a medium or high cervix position. If your cervix is particularly low or you find your vagina to be particularly “tight”, the Merula Cup XL might be too big for you.
      All Merula Cups have the same degree of firmness. The Merula Cup menstrual cup is designed to hold securely and remain leak-free with any pelvic floor muscle condition.
    • Is the Merula Cup really that big?
      The Merula Cup is folded before insertion and is then hardly larger than a tampon. Its soft touch surface makes it very easy and comfortable to insert. That is why the Merula Cup menstrual cup is popular with people of all ages.
    • Can I shorten all of the rungs of my Merula Cup’s ladder?
      We do not recommend this, as it may become difficult to remove the Merula Cup if all rungs of the are removed.

    ABOUT CLEANING

    • How do I clean my Merula Cup?
      Before its first use and after each period, your menstrual cup should be boiled in water (with a splash of vinegar if needed) for 5 minutes. You can clean your menstrual cup either in a saucepan on the stove or in a container in the microwave – the Merula Cupscup is particularly practical for this.
    • Why is it recommended to add a splash of vinegar to the water when boiling a menstrual cup?
      The vinegar in the water counteracts the build-up of lime residue on your menstrual cup. It is however not a must to add vinegar to the water.
    • Can I clean my menstrual cup in the dishwasher or washing machine?
      No. Both the dishwasher and the washing machine do not reach the temperatures required to sterilize a menstrual cup. Additionally, dishwasher cleaners would put a lot of stress on the material of the menstrual cup and possible residues of the dishwasher cleaner and perfumes should not get into the vagina. The same applies to washing machine detergent.
    • My Merula Cup has become slightly discolored, how come?
      Hemoglobin, the blood pigment, stains strongly and can therefore cause discoloration on your menstrual cup. You can counteract the discoloration of your Merula Cup by always rinsing off the blood on your menstrual cup with cold water first. Even with thorough and regular cleaning, a menstrual cup can become discolored over time. However, if it is thoroughly cleaned regularly according to the instructions, there is no need to worry about it.
    • How can I avoid staining or discoloration on my Merula Cup?
      Sometimes the blood pigment hemoglobin in your menstrual blood may cause discoloration of your Merula Cup. To counteract this, we recommend that you first rinse your menstrual cup with cold water each time you clean it.
      However, slight discoloration is normal over time.
      To remove discoloration, soak your cup in a 3% hydrogen peroxide solution overnight. Please note that this procedure may stress the cup’s material and therefore shorten its life span.
    • How can I clean my menstrual cup in a public toilet? Do I have to leave the stall to wash out the Merula Cup?
      To clean your menstrual cup in a public toilet, you do not have to leave the stall. You can easily change the Merula Cup inside the stall and do not necessarily need a sink. For initial cleaning, you can wipe the Merula Cup clean with some toilet paper. If you prefer to rinse it with water, you can also carry a small bottle of water in your handbag. Alternatively, you can take a second clean menstrual cup with you to change out with the already worn one.

    ABOUT THE MERULA CUPSCUP

    • Do other menstrual cups fit in the Merula Cupscup?
      Yes, the Merula Cupscup fits most menstrual cups.
    • Does the Merula Cupscup fit the Merula Cup XL?
      Yes. Of course, the Merula Cup XL fits into the Merula Cupscup. It is of the same overall height as the Merula Cup – while its body is longer, its ladder is shorter.
    • How do I clean my menstrual cup in the Merula Cupscup?
      To clean your menstrual cup with the Merula Cupscup in the microwave, simply fill the Merula Cupscup with clean water up to the marking line, place your previously washed menstrual cup on the blue insert with the opening facing downwards, screw the lid on tightly and open the valve. Then place the Merula Cupscup in the microwave and turn it on at 750 watts for five minutes.
      If the wattage of your microwave differs, adjust the cooking time accordingly. The water in the Merula Cupscup should never evaporate completely. After the boiling process, the Merula Cupscup and its contents may be very hot and hot water or steam may escape.
      Our tip: If necessary, add some vinegar to the water to prevent limescale residue on the menstrual cup and inside the Merula Cupscup.
    • What material is the Merula Cupscup made of?
      The Merula Cupscup is made of polypropylene, a material that is particularly hard and heat-resistant. It also does not contain any harmful plasticizers and is easy to recycle.
    • How do I dispose of the Merula Cupscup?
      If you wish to dispose of your Merula Cupscup after a long period of use, please do so via the residual waste bin.

    GENERAL INFORMATION

    • Why is the Merula Cup available in different colors?
      Because we like the colorful variety and everybody has a different favorite color. 🙂
    • Are the colors safe?
      All colorants used are certified and firmly bonded to the silicone and are therefore, of course, completely harmless.
    • What material is the Merula Cup made of?
      The Merula Cup menstrual cup is made of 100% certified medical silicone. It is also free of plasticizers and animal ingredients. The material of the Merula Cup originates in Germany and is even used for short-term implants.
    • Where is the Merula Cup manufactured?
      The Merula Cup menstrual cup is produced and packaged exclusively in Germany.
    • Why doesn’t the Merula Cup have any small holes on the upper rim as many other menstrual cups do?
      The absence of these holes ensures that the Merula Cup can hold in any condition of the pelvic floor muscles and does not lose its hold but remains tight even after complete relaxation (for example in the morning after getting up). The small holes around the rim of many menstrual cups facilitate air intake into the cup during insertion, allowing its body to unfold more easily. The Merula Cup’s body does not need to fully unfold and therefore does not need these holes.
      Additionally, water often leaks into the menstrual cup through the small holes when bathing or swimming, whereupon it must be emptied promptly to avoid overflowing. This cannot happen with the Merula Cup.
      We strongly advise against adding “air holes” to the Merula Cup yourself, as this would impair its function.
    • Why is there a dark spot on the upper edge of my Merula Cup?
      On this spot, the silicone color mixture is injected through a very small opening into the casting mold. The color pigments come in different sizes. The biggest particles may accumulate during the injection, and at the end of the process they are pushed into the mold and result in a color spot. The color spot has no influence on the functionality of the cup.
      You can find a picture of the color spot here.
    • What is the difference between the cervix and the ectocervix?
      The term cervix refers to the exit of the uterus (womb) into the vagina. The front part of the cervix that protrudes into the vagina is called the ectocervix (also called portio – Latin for “the section”) and is usually round or cone-shaped. It varies between cherry and walnut sized.
      We are actually talking about the ectocervix when we colloquially refer to feeling the cervix to insert the menstrual cup.
    • There is a white residue on my menstrual cup, what could this be?
      A white, powdery residue on your Merula Cup  is usually a sign that lime has settled on your cup during boiling. You can easily avoid this by adding a splash of vinegar to the water when boiling your menstrual cup.
    • Is the Merula Cup FDA registered?
      Yes, the Merula Cup is registered with the U.S. Food and Drug Administration (FDA). You can view the entry here.
    • Are Merula products tested?
      Yes, Merula products are regularly tested by independent laboratories on our account.
