What is a Menstrual Cup and how does it work?

What is a menstrual cup?

A menstrual cup is a bell shaped reusable cup that is used during a woman’s period as an alternative to pads and/or tampons. A menstrual cup is placed inside the vaginal cavity and when fitted securely, will collect (rather than absorb) the menstrual fluid (blood). While the idea of using a menstrual cup is still gaining traction in the wider community, the first menstrual cup was actually designed and patented nearly 80 years ago (in 1935). While the use of menstrual cups is great for the environment and also an excellent financial saving, there are also many other benefits to making the switch to one. A couple of these include less odour, usage time of up to 8 hours, and convenience.

What is a Menstrual Cup made from?

Most reusable menstrual cups are made from medical grade silicone, although a few are also made from TPE (thermoplastic elastomer), or rubber. While many companies now offer coloured cups, others have decided to produce only colourless cups to ensure there is no risk whatsoever of potential chemical leaching into the sensitive vaginal cavity. To add a little bit of colour and feminine prettiness to the menstrual cups, most companies provide coloured carry pouches for cup storage.

Will a Menstrual Cup fit?

Menstrual cups are quite large to look at and can seem daunting to women new to the menstrual cup idea. However, the vagina is a soft and stretchy canal which is designed to stretch larger and then return to its normal size, just as it does during childbirth and sexual intercourse. When folded, the insertion point of the cup can be very similar to the size of a tampon. Menstrual cups usually come in 2 sizes, with the smaller size often being most suited to women under 30 who have not given birth vaginally, and the larger size being for women over the age of 30 who have given birth vaginally. With their growing popularity as an alternative to disposable products, cups are now available in many different sizes and shapes. When choosing the correct size menstrual cup, you may need to also consider your level of flow, cervix height, and pelvic floor strength.

Is a Menstrual Cup suitable for me to use?

Menstrual cups are suitable for women of any age, from teenagers who are only just beginning to menstruate to older women who are going through menopause. 

When you should use caution...

  • Caution should be used by people who have not had penetrative sex, since wearing a menstrual cup does have the potential to stretch and tear the hymen.
  • If you suffer from prolapse or other vaginal conditions, you may need to consult with your physician before using a menstrual cup.
  • Menstrual cups are not designed for use immediately post birth, since the uterus and vaginal canal need time to heal after the birthing process.
  • Menstrual cups cannot be used during sex. If you would like something suitable to use during period sex, then a menstrual disc is the solution! 
  • Since Menstrual cups are used internally, there are some situations in which medical advice should be sought prior to using one. 

Using a Menstrual Cup

If you are new to menstrual cups, it is realistic to allow two to three cycles for getting used to correctly inserting and removing the cup. You may also decide to wear a liner the first few times as added protection should you experience any leaks.

1. Inserting

To insert a menstrual cup, you will wash your hands and then fold the cup in the way that suits you best. You then need to gently insert the folded cup just inside the entrance of the vaginal canal (following the instructions included with your cup). Once inserted, the cup will pop open and is then ready to begin collecting menstrual fluid.

2. Removing

Each Menstrual cup is designed with a stem. When it comes time to remove the cup, wash your hands and use the stem to guide your fingers to the base of the cup (do not pull the cup out by the stem). You will then carefully pinch the base to release the suction and slowly remove the cup from the vaginal canal.

3. Cleaning

Cleaning a menstrual cup is as simple as rinsing it under cold running water between changes and then boiling it in a pot of water for 10-20 minutes to sterilise it at the end of your cycle (or according to your brands directions). It can then be safely stored in the carry pouch that is included with most cup brands. You should not store a menstrual cup in an airtight container.

As with any form of feminine hygiene product, proper hygiene and hand and cup washing procedures should be followed to reduce the risk of possible infection.
