What Is A Menstrual Cup?

A menstrual cup is a reusable, small, bell-shaped product with a stem at the base made from medical-grade silicone, rubber, latex, or elastomer. It is designed to be inserted into the vagina to collect menstrual fluid during your period, whilst the stem helps with removal and can be trimmed to fit your comfort. 


Unlike disposable options, menstrual cups are an eco-friendly alternative to other feminine hygiene products and can last for years with proper care – saving the environment with significantly less waste and more money in your pocket.


Menstrual cups come in different sizes, typically small and large, to accommodate the differences in anatomy and menstrual flow. The choice between sizes often depends on factors like age, childbirth history, and flow volume. It’s essential to select the right size for your comfort and the overall effectiveness of the product.

How Do Menstrual Cups Work?

Menstrual cups work by creating a seal and suction inside the vagina, creating a wall to prevent leaks and effectively collecting menstrual fluid. Here’s a more detailed look at how they operate:


  • Insertion: To use a menstrual cup, fold it into a U shape and insert it into the vagina. Once inside, the cup opens up, forming a seal against the vaginal walls.
  • Collection: As blood flows into the cup, it is collected and held in the cup until it’s time to empty it. The capacity of a menstrual cup varies between brands and sizes, but it generally ranges from 15 to 30 millilitres.
  • Removal: To remove the cup, gently break the seal by pinching the base, then pull it out. Empty the contents into the toilet, rinse the cup, and reinsert as needed.


One of the primary advantages of menstrual cups is their longer wear time. You can wear them for up to 12 hours, making them convenient for overnight use and long days, unlike other forms of feminine hygiene products. They also last up to 10 years, meaning you’ll save money from buying other menstrual products over the years.

How to Insert a Menstrual Cup

Inserting a menstrual cup may seem daunting at first, but with practice, it becomes second nature. Here’s a step-by-step guide:


  1. Wash your hands: Ensure you wash your hands thoroughly to maintain hygiene.
  2. Fold the cup: Fold the cup into a “C” or “U” shape to make it easier to insert. There are various folding methods – find what works best for you.
  3. Relax: Find a comfortable position, like squatting or sitting on the toilet, and relax your pelvic muscles.
  4. Insert the cup: Gently insert the folded cup into your vagina at a 45-degree angle, aiming towards your tailbone.
  5. Allow it to open: Release the fold and let the cup open fully. You should feel a slight resistance when it forms a seal.
  6. Check the seal: Run your finger around the base to ensure the cup has fully opened and created a seal. A proper seal is crucial for leak prevention.


How to Remove a Menstrual Cup

It’s important to remember to remove your menstrual cup at least once every 12 hours, depending on your flow. Removing a menstrual cup is simple, but it’s important to do it carefully to avoid spills or discomfort:


  1. Wash your hands: Again, cleanliness is essential.
  2. Relax: Find a comfortable position and relax your muscles.
  3. Pinch the base: Gently pinch the base of the cup to break the seal. This is a crucial step to avoid discomfort during removal.
  4. Remove slowly: With the seal broken, carefully pull the cup out. Keep it upright to prevent spillage.
  5. Empty and rinse: Empty the contents into the toilet, rinse the cup with water, and reinsert as needed. If you’re in a public space, you can use a bottle of water to rinse in the cubicle or use a menstrual cup wipe.
