Quick Answer

Choose the MeLuna Classic Ball Stem if you're new to cups or have an average cervix. Pick the Sport Shorty if you have a low cervix, need a firmer cup for intense activity, or prefer a shorter cup.

Stem vs Shorty: What's the Real Difference?

The main difference is the stem. A ball stem gives you a grip to help with removal, while a shorty cup has a shorter body and stem, making it a better fit for a low cervix. The trade-off is that a shorter cup can be harder to grip, especially if your fingers are longer or your cervix sits higher.

The Classic Ball Stem is made of soft TPE and is designed for most women, making it a forgiving option if you're still learning insertion. The Sport Shorty is firmer—25% firmer than the Classic—which helps it spring open even under strong muscle pressure, but that firmness can feel intense if you have a sensitive bladder or are new to cups.

Trade-Offs to Consider

  • Cervix Height: If your cervix is low, the Shorty's shorter body and stem will be more comfortable. If your cervix is average or high, the Classic Ball Stem's longer body is easier to reach. Measure your cervix height on the heaviest day of your period.
  • Firmness: The Classic is soft and flexible, which is gentle for beginners. The Sport is 25% firmer, so it springs open more reliably but can be more intense to insert. If you've never used a cup, start with the Classic; if you have leaks during exercise, try the Sport.
  • Removal Grip: The ball stem on the Classic gives you a clear grip for removal. The Shorty has a shorter stem, so you may need to bear down or reach higher to remove it. Practice removal in the shower where you can relax and reach comfortably.
