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.

I love this! After failing to use a more traditionally shaped cup a few years ago, I decided to try again after researching cups to fit a low cervix. In the mean time I had also had a baby, which actually made things a lot easier. I found the best way to make sure it was suctioned correctly was to check my cervix position before every time I re-inserted it, and my cervix is a lot easier to find now. The first few days I had a few misses where it leaked due to incorrect placement, but I got the hang of it very quickly. I feel confident using it after just one period. It was my first post-partum period so it was quite heavy and even still I was only emptying it once every 6 hours at most.

I love my Merula cup. I have a very low cervix and a strong first two days and the Merula cup just works great for me.

Finally found my cup! Easy to insert, no sliding, and the ladder pull makes removal so easy and mess free. All the issues I had with my other cups that I had used prior to children were solved with this cup.

This is the second Merula I have bought, may first one lasted about 4 years so saved me lots on money on disposables in that time!

I wanted to love this cup, I really did, but this cup just didn’t want to love me back.
The cup looks good, the ladder-style stem is ingenious, and the range of bright colours is definitely fun. I was also eager to try out a softer silicone than my original cup. Unfortunately, after months of struggle, and a steep learning curve, I found myself simply too frustrated to continue.
The biggest struggle I faced was getting the cup oriented correctly. The round shape means that you have to be aware of which side is “up” when inserting the cup, otherwise it will not catch much by way of blood. My tip for anyone trying this cup is to insert it a little deeper than needed and then give the stem a tug to help “centre” it within your vagina.
I also had trouble getting the softer silicone to unfold, and it was difficult to be sure that the rim had opened fully.
Lastly, I was never able to get this cup to form a seal. It leaked the entire time I used it; and it “leaked” even more, and sooner, when it wasn’t seated or unfolded correctly. It made it difficult to know when it was time to empty as the cup would be slippery and move around all the time.
Please understand that I don’t fault the cup! Everyone’s anatomy is different and this one just didn’t work for me. The good news is that I now have the Merula XL and it works a dream.

A very steep learning curve. I have given 3 stars after just one cycle so I am sincerely hoping for an improved experience next cycle. I would strongly recommend looking at YouTube reviews to get an idea of how this cup should be used compared to the more “traditional” designs. Not all bad though. I do enjoy the black colour option, and the ladder style stem.

I originally got this because I was looking for a larger and more comfortable shape than the juju cup I’d been using. It took a few tries to figure out how to insert it but the punch down method works really well and I’m super happy.
Incredibly comfortable, easy to clean and very high quality silicone. I switched to a menstrual cup a few years and I’ll never go back to disposables. The cup is just too convenient.

Gives me the worst cramps I’ve ever had.

Great for a high cervix with the ladder. I’ve used three different cups previously and this one is definitely best fit for me.

I’ve been using cups on and off for 10 years and tried this one as I have heavy flow for a couple of days at the start of my cycle.
I’m pleased with the cup, but it is not as user friendly as other cups I have used.
Pros – capacity + less noticable once placed (I have to place cups high which can cause irritation).
Cons – more difficult to place (doesn’t open up consistently as silicone is more pliable and due to shape) + more difficult to remove.
Would not recommend for first timer.

I am not a first time cup user and I found this very awkward to insert and didn’t seal very well, led to a lot of leakages. Really uncomfortable and caused painful cramping. Also awkward to remove because you have to stick your fingers inside to slightly crush the cup to break the seal, as there are no vent holes around the edge. Would not recommend.

This is my ‘goldilocks’ cup… and definitely will be yours too! Totally recommend to everyone!
((The first cup I tried was way too long; had to be emptied often; and leaked a lot… I wasn’t a happy chappy.)
The Merula is very easy to use; easy to insert & remove; no leaks or nasty surprises during the day or at night; easy to clean; gorgeous little storage bag! Xx
