Menstrual cup: Why switch to this sustainable option?

What is a menstrual cup, and how does it work?

A menstrual cup is a reusable sanitary product that collects menstrual fluid rather than absorbing it. Made of medical-grade silicone, natural latex, or TPE, it takes the form of a small, flexible cup with a stem for easy removal. It is inserted into the vagina, where it unfolds and forms a tight seal against the vaginal walls, preventing any leaks. Because it has a larger capacity than tampons, it can be worn for up to 12 hours, including overnight. When properly cared for, a menstrual cup can be used for up to 10 years, making it both the most economical and the most environmentally friendly option among all menstrual products.

How do you choose the right size menstrual cup?

The size determines the comfort and effectiveness of the cup. Several factors influence the choice:

• Vaginal delivery: A larger size is generally recommended after a vaginal delivery, as the pelvic anatomy has changed.
• Flow intensity: A larger cup offers increased capacity for heavy flow.
• Pelvic floor tone: A toned pelvic floor may require a more flexible cup.
• Age and body type: Smaller, more flexible models are available for teenage girls or women who have not yet been sexually active.

Consult the manufacturers’ size charts, and if in doubt, consulting a healthcare professional is the best approach for your first purchase.

What are the best care practices?

Proper hygiene is essential to preserve the vaginal flora and prevent infection:

• Rinse with cold water each time you empty it to prevent blood proteins from setting.
• Wash with a mild, hypoallergenic, unscented soap, then rinse thoroughly.
• Sterilize by boiling for 5 to 10 minutes before first use and between each cycle.
• Store in a breathable fabric pouch between cycles; never in an airtight container.
• Use alcohol-free, biodegradable wipes for quick cleaning when changing the cup while on the go.

Thorough care minimizes the risk of toxic shock syndrome, which is already very low with the menstrual cup compared to tampons.

Is the menstrual cup suitable for all situations?

The menstrual cup is suitable for the vast majority of users and activities:

• Sports and swimming: its leak-proof design allows you to participate in all water sports without the risk of leaks.
• Overnight: Its high capacity allows it to be worn for 10 to 12 hours without emptying.
• Teenagers: Specifically soft and small-sized models are available.
• Heavy flow: The cup offers significantly greater capacity than super-absorbent tampons.

If you have an IUD (intrauterine device), a prior gynecological consultation is recommended to ensure that the cup will not pull on the strings and dislodge the device. Particular care must then be taken during insertion and removal.

What risks should you be aware of before using a menstrual cup?

The safety profile of the cup is generally very favorable. The rare complications reported include:

• Vaginal irritation in cases of silicone or latex allergy—in which case, opt for a latex-free TPE cup.
• Yeast infections or vaginal flora imbalances if hygiene is inadequate or if a harsh soap disrupts the vaginal pH.
• A significantly lower risk of toxic shock syndrome than with tampons, but not zero if worn for more than 12 hours.

After an infection, supporting the vaginal flora with Lactobacillus-based probiotics can help restore balance more quickly.

Is it normal to have an adjustment period when using a menstrual cup?

Yes: most new users need one to two menstrual cycles to master insertion and removal. Folding techniques (C-fold, punch-down fold) help compact the cup for insertion. Once properly positioned, the cup should not be felt. If discomfort persists, check the folding, size, and position. Women with sensitive skin or mucous membranes may find a higher-quality medical-grade silicone more comfortable. After each successful emptying, the process quickly becomes second nature.
