Navigating the world of menstrual products can feel overwhelming, with countless options vying for your attention. Among the innovative solutions available today, the menstrual cup has emerged as a game-changer for many, offering an eco-friendly, cost-effective, and comfortable alternative to traditional pads and tampons. If you’re seeking a period product that promises exceptional capacity and a unique design, the Merula Menstrual Cup stands out as a strong contender, engineered to provide unparalleled protection and comfort.

What is the Merula Menstrual Cup?
The Merula Menstrual Cup is a distinctively designed period product, crafted from 100% medical-grade silicone. Unlike many conventional cups, the Merula boasts a spherical, “short and stout” body, which contributes to its impressive capacity without being excessively long. It features a smooth exterior and, notably, has no air holes, contributing to a strong, reliable seal. Another signature element is its flexible, ladder-shaped stem, which can be trimmed to suit individual comfort and cervix height.
When compared to disposable pads and tampons, menstrual cups like the Merula offer a myriad of benefits. They are reusable for many years, drastically reducing waste and saving money in the long run. By collecting rather than absorbing menstrual fluid, cups help maintain the natural vaginal pH balance and avoid the dryness often associated with tampons. The Merula, in particular, distinguishes itself with its high fluid capacity, allowing for longer wear times—up to 12 hours—even on heavier flow days. While traditional cups generally offer these advantages, the Merula’s specific design aims to solve common challenges, such as accommodating a low cervix or ensuring a secure fit despite varying pelvic floor strengths.
However, like any product, the Merula Cup has its unique considerations. Its firmer silicone and strong suction can take a bit of a learning curve for some users, potentially causing initial bladder pressure or mild cramping if not inserted correctly. Yet, for many, these minor adjustments are a small price to pay for the freedom and reliability it offers.
Merula Cup Types and Sizes
The Merula Menstrual Cup simplifies sizing with primarily two options, each designed to cater to different needs while maintaining the brand’s signature spherical shape and high capacity.
Merula Cup “One Size”
This model is the flagship “one size fits most” cup, developed to accommodate a broad range of menstruators. With a generous capacity of up to 38 ml, it significantly surpasses many standard menstrual cups. Its short body (approximately 39 mm without the stem) combined with the adjustable ladder stem makes it particularly suitable for individuals with a low cervix, as it can sit comfortably without protruding. Conversely, users with a higher cervix can utilize the full length of the trimmable ladder stem, making it versatile for nearly all cervix heights and varying pelvic floor muscle conditions.
Merula Cup XL
Designed specifically for those experiencing particularly heavy bleeding, the Merula XL offers an exceptional capacity of 50 ml, making it one of the largest menstrual cups available on the market. This extra capacity can be life-changing for individuals who typically fill smaller cups in just a few hours. The Merula XL is generally recommended for users with a medium to high cervix. Its firmness and larger dimensions mean it might not be the ideal choice for those with a very low cervix or a particularly “tight” vaginal canal.
The spherical shape is a cornerstone of the Merula design philosophy. This unique form factor allows the cup to hold a large volume of fluid while maintaining a shorter overall height compared to many tapered cups. This design is crucial for maximizing capacity, ensuring a comfortable fit, and adapting to the body’s natural anatomy, whether the cup is fully unfolded or remains slightly “scrunched” inside.
Choosing the Right Merula Cup Size: A Detailed Guide
Selecting the perfect menstrual cup involves considering your unique anatomy and menstrual flow. The Merula Cup, with its innovative design, offers solutions for many, but a personalized approach will ensure the best experience.
Key Factors for Merula Cup Selection
- Cervix Height: This is arguably the most crucial factor for any menstrual cup. The Merula “One Size” is exceptionally versatile due to its short body and trimmable ladder stem. If you have a low cervix, the “One Size” is often recommended as it can be worn lower and the stem can be trimmed significantly. For a medium to high cervix, both the “One Size” (with an untrimmed or minimally trimmed stem) and the Merula XL can work, depending on your flow. The Merula XL’s shorter overall height (despite its larger capacity) can also be beneficial for those with a medium cervix who need more volume.
- Flow Intensity: Merula cups are renowned for their high capacity. If you experience a moderate to heavy flow, the “One Size” (38 ml) will likely provide extended wear time. For very heavy periods, where you might typically change a Super Plus tampon hourly, the Merula XL (50 ml) is specifically engineered to offer maximum protection and peace of mind.
- Pelvic Floor Strength: Merula cups are designed to be effective regardless of your pelvic floor muscle tone. Their firm yet adaptable medical-grade silicone ensures a secure fit whether you have strong or relaxed pelvic floor muscles, reducing the risk of leaks often associated with softer cups.
How to Determine Your Cervix Height
While Merula is quite forgiving, knowing your cervix height can help guide your choice. During your period, insert a clean finger into your vagina. Feel for a firm, round, slightly spongy area, similar to the tip of your nose.
- Low Cervix: You can feel your cervix easily, typically at the first knuckle (approx. 1.5-2 inches).
- Medium Cervix: You can feel your cervix at the second knuckle (approx. 2-3 inches).
- High Cervix: You can barely reach your cervix, or not at all (over 3 inches).
For Merula, if you have a low cervix, the “One Size” is generally the safest bet. If your cervix is medium to high, both “One Size” and XL are possibilities, with XL being the choice for significantly heavy flows.
Advice for First-Time Merula Users
If you are new to menstrual cups, starting with the Merula “One Size” is often recommended. Its adaptability makes it a forgiving choice. Pay close attention to insertion techniques and allow yourself a few cycles to get comfortable. The learning curve is normal, and patience is key to mastering its use.
How to Use Your Merula Menstrual Cup
Using a menstrual cup can seem daunting at first, but with practice, it quickly becomes second nature. The Merula Cup, with its unique design, has some specific tips for optimal comfort and leak-free protection.
Preparation
Before your first use and after each menstrual cycle, sterilize your Merula Cup by boiling it in water for at least 5 minutes. You can use a dedicated Merula Cupscup or a microwave-safe container with a pinch of vinegar to prevent mineral buildup. Always ensure the cup is fully submerged and doesn’t touch the bottom of the pot to avoid damage. For daily use, simply wash your hands and the cup with warm water and a mild, pH-balanced cleanser. Using a water-based lubricant can make insertion smoother, especially for beginners.
Folding Techniques
The Merula Cup is quite firm, so a good folding technique is essential for comfortable insertion. The punch-down fold is often recommended for the Merula:
- Push one side of the rim down towards the inside base of the cup.
- Fold the other side of the cup over to create a narrow, pointed insertion tip.
Another popular method is the ‘7’ fold or ‘C’ fold, though the punch-down tends to create a smaller insertion point for Merula. Experiment to find what works best for you.
Insertion Tips
- Relaxation is Key: Find a comfortable position (squatting, sitting on the toilet, or standing with one leg up). Relaxing your pelvic floor muscles is crucial.
- Angle and Placement: Wet the folded cup with water or lubricant. Insert the folded cup at a slight angle, aiming towards your tailbone, not straight up.
- Opening the Cup: Once the cup is mostly inside, release your grip and allow it to open. The Merula Cup does not need to open completely; as long as the rim is unfolded and creates a seal around your cervix, the body of the cup can remain slightly “scrunched” or adapt to your anatomy.
- Checking the Seal: Gently rotate the cup or pull slightly on the stem. If you feel resistance, it’s likely sealed. You can also run a finger around the base of the cup to ensure it has fully expanded and your cervix is comfortably nested inside the cup. Some users find it helpful to press the pelvic floor downwards or gently “screw” the cup upwards to ensure it fully opens and positions correctly around the cervix.
Removal Tips
- Break the Seal: This is the most important step for comfortable removal. Insert a clean finger and gently press inwards on the side or base of the cup to break the suction seal. You might hear a slight “pop.”
- Gentle Wiggling: Once the seal is broken, gently pull the ladder stem downwards with slow, zigzag movements until you can reach the base of the cup.
- Fold and Remove: Pinch the base of the cup to keep it folded and carefully remove it. Empty the contents into the toilet.
- Cleaning: Rinse the cup immediately with cold water to prevent staining, then wash thoroughly with warm water and a mild, unscented soap designed for intimate hygiene. Reinsert or store it as needed.
Cleaning and Storage
After each period, boil your Merula Cup for 5 minutes. Between cycles, store it in the breathable cotton pouch provided (or another air-permeable container) in a clean, dry place. Avoid airtight containers, which can encourage bacterial growth or odor.
Where to Buy the Merula Menstrual Cup
When investing in a personal health product like a menstrual cup, ensuring authenticity and quality is paramount. The Merula Menstrual Cup, a German-made product, is available through various channels.
Authorized Retailers
The most reliable places to purchase a Merula Cup are through its official website or from authorized online and offline retailers. Official websites often provide the most comprehensive product information, sizing guides, and customer support directly from the brand. Authorized retailers, such as reputable period product stores or pharmacies specializing in feminine hygiene, are also trustworthy sources. They ensure you receive a genuine product made from 100% medical-grade silicone, free from harmful additives.
Online vs. Offline Shopping
- Online: Shopping online offers convenience and a wider selection of colors and sizes, including both the “One Size” and Merula XL. Websites often feature user reviews, which can be invaluable for understanding different experiences with the cup. Be sure to check the retailer’s return or exchange policy, as menstrual cups are personal hygiene items and may have restrictions.
- Offline: Purchasing from physical stores allows you to see the product in person (though usually packaged) and speak with store associates who may offer guidance. However, availability might be limited compared to online stores.
Important Considerations When Buying
- Authenticity: Always verify that you are buying from a legitimate seller to avoid counterfeit products, which may use inferior materials that could be unsafe.
- Sizing Information: Double-check the sizing charts and descriptions, especially for the Merula XL, to ensure it aligns with your cervix height and flow needs.
- Reviews: Reading user reviews can offer practical insights into the cup’s performance, comfort, and potential challenges for different body types.
- Price: While price shouldn’t be the sole determining factor, be wary of deals that seem too good to be true, as they might indicate a non-authentic product.

Frequently Asked Questions
Is the Merula Cup comfortable?
Comfort with the Merula Cup can vary. Its firmer silicone and unique spherical shape may take some getting used to. Many users find it incredibly comfortable once properly inserted, often forgetting it’s there due to its secure fit and high capacity. Some individuals, particularly those new to menstrual cups or sensitive to firmer cups, might initially experience mild pressure or discomfort until they master insertion and removal.
Can the Merula Cup be worn overnight?
Yes, the Merula Cup is designed for extended wear, typically up to 12 hours, making it an excellent option for overnight use. Its high capacity, especially the XL version, ensures leak-free protection even during heavy sleep, allowing for uninterrupted rest without worrying about frequent changes.
Is the Merula Cup hard to remove?
Due to its unique design without air holes, the Merula Cup creates a strong seal, which can sometimes make removal seem challenging initially. However, by properly breaking the suction seal—by pressing firmly on the side or base of the cup—and gently wiggling it down using the ladder stem, removal becomes straightforward with practice.
Does the Merula Cup cause bladder pressure?
Some users, particularly with the Merula XL or if the cup isn’t positioned perfectly, may experience slight bladder pressure due to its firmness. This sensation often diminishes as one becomes accustomed to the cup or by adjusting the insertion angle slightly. If persistent, it might indicate the cup size or firmness isn’t ideal for your anatomy.
How often do I need to empty my Merula Cup?
The frequency of emptying your Merula Cup depends on your menstrual flow. With capacities of 38 ml for the “One Size” and 50 ml for the XL, Merula cups generally allow for up to 12 hours of wear, even on heavier days. This means most users can empty it in the morning and evening, significantly reducing bathroom trips compared to other period products.
