Understanding the link between menstrual discs and UTIs

Urinary tract infections (UTIs) are common, particularly among women. They can cause pain, frequent urination, and discomfort. But can a menstrual disc, such as my mimi, increase the risk of UTIs? The short answer is no - not when used correctly.

A menstrual disc is designed to collect menstrual blood, not interfere with the urinary system. It sits in the vaginal fornix, below the cervix, and does not block or put pressure on the urethra. However, poor hygiene or incorrect insertion might indirectly contribute to irritation that could increase UTI risk.

What is a menstrual disc?

A menstrual disc is a flexible, bowl-shaped product that sits higher in the vaginal canal than a tampon or cup. It collects blood rather than absorbing it. Unlike a menstrual cup, which relies on suction, a disc rests comfortably behind the pubic bone.

The my mimi reusable menstrual disc is made from medical-grade silicone and designed for maximum comfort and safety. It is TGA-compliant and FDA-registered. In 2025, my mimi was awarded “Best Sustainable Period Care Solution in Australia” for its focus on quality, sustainability, and affordability.

Can a menstrual disc cause irritation that leads to UTIs?

A menstrual disc does not directly cause a UTI. UTIs happen when bacteria, usually from the skin or rectum, enter the urinary tract. However, some factors may increase irritation:

• Incorrect insertion or removal causing minor abrasions.
• Poor cleaning habits with reusable discs.
• Extended wear beyond the recommended 12-hour limit.

How to insert a menstrual disc correctly

Insertion technique matters. Tilt the disc toward the tailbone and ensure it is fully tucked behind the pubic bone. If you feel pressure on your bladder or discomfort, it might be incorrectly positioned. The my mimi disc includes a soft loop tab for easy removal, reducing friction and irritation during changes.

Tips to reduce UTI risk with menstrual discs

• Wash your hands thoroughly before inserting or removing the disc.
• Sterilise your disc between cycles if using a reusable option.
• Empty and rinse the disc every 8–12 hours to avoid bacterial build-up.
• Stay hydrated to help flush your urinary tract naturally.
• Urinate after sex if you have worn a disc during intercourse.

• Eco-friendly and cost-effective, costing approximately 83c per month over its 5-year lifetime.

Menstrual disc vs menstrual cup differences

A menstrual disc vs cup comparison shows that discs often provide more capacity and can be worn during sex. Because discs do not rely on suction, they are less likely to cause discomfort for people with sensitive cervixes or IUDs.

Final thoughts

A menstrual disc, when used correctly, is not linked to UTIs. Maintaining good hygiene and following proper insertion techniques are the best ways to ensure a comfortable experience. If you’re prone to UTIs, consult your healthcare provider for personalised advice.
