If you've been researching menstrual discs, you've probably seen the term medical-grade silicone mentioned frequently.

But what exactly does it mean, and why is it important when choosing a menstrual disc?

Because menstrual discs are worn internally for extended periods, the material they are made from plays a significant role in safety, comfort and long-term performance. Understanding medical-grade silicone can help you make a more informed decision when selecting a reusable period product.

What is medical-grade silicone?

Medical-grade silicone is a high-quality silicone material specifically designed for use in healthcare and medical applications.

It is commonly used in products that come into direct contact with the human body, including:

• Medical tubing
• Catheters
• Wound care products
• Respiratory equipment
• Implantable medical devices
• Menstrual discs and menstrual cups

Medical-grade silicone is valued because it is highly stable, durable and compatible with human tissue.

Why is medical-grade silicone used in menstrual discs?

Menstrual discs are designed to sit inside the vaginal fornix for several hours at a time, often for up to 12 hours depending on flow and individual circumstances.

Because of this, the material needs to be suitable for prolonged internal contact.

Medical-grade silicone offers several advantages that make it well suited for menstrual disc use.

1. Biocompatibility

One of the most important characteristics of medical-grade silicone is biocompatibility.

This means the material is designed to work safely alongside the body's tissues without causing harmful reactions when used as intended.

Biocompatibility testing helps assess factors such as irritation potential, tissue compatibility and overall safety.

2. Soft and flexible comfort

Menstrual discs need to be flexible enough to fold during insertion while maintaining enough structure to remain securely positioned.

Medical-grade silicone provides this balance by offering:

• Flexibility for insertion
• Comfort during wear
• Shape retention
• Long-term durability

The result is a material that can adapt to the body while maintaining reliable performance.

3. BPA-free and latex-free

High-quality medical-grade silicone is naturally free from BPA and latex.

This can be beneficial for individuals who wish to avoid certain materials or who have latex sensitivities.

Many menstrual disc users specifically seek products manufactured from BPA-free materials as part of their purchasing decision.

4. Long-lasting durability

Unlike disposable period products, reusable menstrual discs are designed for repeated use over several years.

Medical-grade silicone is highly durable and resistant to cracking, breaking or degrading when properly cared for.

This durability allows many reusable menstrual discs to remain effective for up to five years.

Does medical-grade silicone absorb fluids or odours?

Medical-grade silicone is a non-porous material.

This means it does not readily absorb menstrual fluid, odours or moisture in the same way that some porous materials can.

When cleaned according to the manufacturer's instructions, medical-grade silicone helps support hygienic reuse throughout the product's lifespan.

How is medical-grade silicone tested?

Manufacturers of medical-grade silicone products typically undertake testing to verify material quality and safety.

Depending on the product and regulatory requirements, testing may include:

• Biocompatibility assessments
• Material composition verification
• Cytotoxicity testing
• Irritation testing
• Sensitisation testing

These assessments help ensure the material is suitable for its intended use.

Are all silicone menstrual discs the same?

No.

While many menstrual discs are made from silicone, the quality and grade of silicone can vary between manufacturers.

When comparing products, it is worth looking for brands that clearly disclose:

• The use of medical-grade silicone
• Regulatory compliance information
• Material safety information
• Product testing standards

Transparent information helps consumers make informed decisions about the products they use.

Why material quality matters for reusable period care

A reusable menstrual disc may be worn hundreds of times throughout its lifespan.

The quality of the material directly affects:

• Comfort
• Durability
• Safety
• Ease of cleaning
• Long-term reliability

Choosing a menstrual disc made from high-quality medical-grade silicone can provide greater confidence in the product's performance over time.
