The stem is the small extension at the base of your menstrual cup. It helps you remove the cup when your period is over. Different cups have different stem types. Each one works a bit differently. Finding the right stem type can make your cup more comfortable and easier to use.

Common Stem Types

Most menstrual cups come with one of these five stem types. Each has its own benefits.

Ball Stem

A ball stem is round and easy to grip. It looks like a small ball at the base of your cup. Many women find this type easy to hold when removing the cup. The ball shape gives you something solid to grasp. It works well if you have a high cervix and need extra length to reach your cup.

Ring Stem

A ring stem is a loop at the bottom of the cup. You can hook your finger through it. This makes removal simple and secure. Some women prefer the ring because it gives them extra control. It's also easy to trim if you need a shorter stem.

Flat Stem

A flat stem is thin and wide. It has a slim profile that some women find more comfortable. The flat shape takes up less space inside you. This type is popular with women who find other stems bulky. You can still grip it firmly when you need to remove your cup.

Hollow Stem

A hollow stem has a tube-like shape with space inside. This makes it flexible and soft. Many women say it's the most comfortable stem type. The hollow design bends with your body. It's less likely to poke or irritate you. This stem works well if you have a sensitive vaginal opening.

No Stem

Some cups have no stem at all. They have a smooth, rounded base instead. This streamlined design is very comfortable once you get used to it. Women with a low cervix often prefer stemless cups. The cup sits lower and doesn't need extra length.

Choosing the Right Stem

Your cervix height is the most important factor. If you have a high cervix, you'll want a longer stem like a ball or ring. This gives you something to reach and grasp. If you have a low cervix, a shorter flat stem or no stem works best. A long stem might poke outside your body and feel uncomfortable.

Think about how you'll remove your cup. If you're nervous about removal, a ring or ball stem gives you more to hold onto. If you're confident with removal technique, you might prefer a flat stem or no stem for comfort.

Stem Customization

You can trim most stems to fit your body better. Many women cut their stems shorter for more comfort. Here's what you need to know:

Use sharp scissors to cut the stem cleanly
Trim a little bit at a time—you can always cut more
Sand rough edges with a nail file if needed
Test the cup after each trim to check comfort
Never cut above the base of the cup itself

Some women remove the stem completely. This is safe if you feel comfortable removing your cup without it. Just make sure you can reach the base of the cup to break the seal.

Comfort and Positioning

The stem should sit comfortably inside you. You shouldn't feel it when you're sitting, walking, or moving. If the stem pokes out or causes irritation, it's too long. Try trimming it shorter.

Remember that your cup sits lower in your vagina than a tampon. The stem will be closer to your vaginal opening. This is normal. As long as it's not poking outside your body, the position is correct.

Finding Your Perfect Match

The best stem type is the one that feels comfortable and helps you remove your cup easily. Many women try different stems before finding their favorite. Our Cup-Figurator quiz considers your cervix height and experience level to recommend cups with the right stem type for you.

Don't be afraid to experiment. You might find that removing the stem completely gives you the comfort you need. Or you might love the security of a ring stem. Every woman is different. What matters is finding the stem that works for your body.
