What is the Merula One Size Cup?

Made in Germany from 100% medical-grade silicone, the Merula Cup is an excellent option for women with any cervix height and any degree of pelvic floor strength (or lack of). As one size fits most and one of the highest-capacity cups on the market, the Merula can hold up to 38ml of menstrual fluid. This is around 10-15ml more than most other cup sizes. Not only will this higher capacity mean fewer bathroom trips throughout your day, the vibrant colours and the coordinating cotton pouch will just make your day feel that little bit brighter.

The Merula is designed in such a way that it does not need to be completely open after insertion. As long as the edge has opened, the cup itself can be worn in a folded state, while still providing leak-free protection. The exterior of the Merula is smooth, with no protruding top rim. This makes it more comfortable for women who experience discomfort from other ‘rimmed’ cups. The unique 3 rung ladder stem can be easily trimmed and allows for easier cup removal, and the more spherical shape of the Merula means it is more suited to varying cervix heights. Finally, the lesser vacuum level of the Merula makes this cup suitable for any pelvic floor condition, whether weak or very strong.

If you have a very heavy flow, you may find the 50ml capacity of the Merula XL more suitable.

Size Guide:

The Merula is a ‘one size’ cup that is designed to fit women of all ages, stages of life, and cervix heights.

How to use the Merula Cup:

The Merula menstrual cups work differently from traditional bell-shaped cups, and therefore, may require a few cycles to adapt to (particularly if you have used traditionally shaped cups previously). While most bell and v-shaped cups are designed to sit below the cervix, the Merula is designed to have the cervix sitting within it. We recommend watching the instructional video to learn how to correctly insert and remove the Merula. We have also listed a few other helpful tips to get you started.

  1. Always wash your hands before and after using the Merula Cup.
  2. Before inserting the cup, feel for your cervix. Fold the cup into the punch down fold to insert it. Once inserted, push the cup in the direction of the cervix and open it in front of the cervix/push the cup onto the cervix while opening the cup.
  3. To help the cup open, push into the folded side of the cup and gently press away the vaginal wall to create more space. Once the Merula Cup’s rim has expanded and created a slight suction on the vaginal wall (this is hardly noticeable), its body can be worn squished and does not have to expand fully.
  4. Sometimes using a water-based(!) lube can be helpful. Apply the water-based lube on the cup’s rim, additionally, it can be helpful to also apply the water-based lube on your cervix. This helps the cup to slide onto the cervix easier.
  5. The Merula Cup must not be removed by solely pulling on the ladder stem. It is important that the seal is first released. If the cup is positioned high up within the vaginal canal, you can hold the stem and gently move the cup down using ‘zig-zag’ movements. Once you can reach the cup, break the seal by pressing against the cup body, and proceed to remove as normal.

How to Clean the Merula Cup:

Sterilise the cup before first use, and again after each menstrual cycle. This can be done by adding a pinch of vinegar to a pot of boiling water and sterilising the cup for 5 minutes. It can also be done with the use of a microwave steriliser such as the Ruby Clean.

When you empty the cup, rinse it under cold water in order to prevent staining. Before reinserting, clean it with some warm water and a suitable menstrual cup wash.

If you are out and about and find that you have to empty your Merula without access to a private sink, you can simply wipe it with toilet tissue, or use some menstrual cup wipes. You may also like to take some bottled water with you for rinsing your cup. Properly wash your cup when next able to do so.

Keep the cup in a pouch or container that provides adequate airflow. If maintained properly, your Merula cup should last for several years. If there are any signs that the silicone may be deteriorating, it is time to buy a new one. Slight staining due to regular use is normal.
