IUDs are effective, and should be essentially forgettable contraception. And the medicated IUDs generally prevent women from having menstrual periods. However some of the users will still have periods. Menstrual cup use can still be safe and effective for IUD users. In many cases the menstrual cup sits mid vagina and doesn’t actually hug the cervix, therefore may not even touch the strings. There are no studies to say that concomitant use of both an IUD and a Menstrual Cup together reduces contraceptive effectiveness. There were seven cases recently reported to the journal Contraception, wherein IUD expulsion occurred during concomitant menstrual cup use, and we say that just be aware, and check your strings after menstrual cycles with a menstrual cup use.
Benefits of Using a Menstrual Cup
Menstrual cups offer several advantages beyond convenience—and many patients appreciate them once they learn how they work.
✔️ Environmentally Friendly
Unlike disposable pads or tampons, a menstrual cup is reusable for years. This significantly reduces waste and the environmental footprint associated with menstrual products.
✔️ Cost‑Effective
Although the upfront cost is higher, most cups last 2–10 years, making them far more economical over time compared with purchasing monthly supplies.
✔️ Longer Wear Time
Cups can typically be worn for up to 12 hours, depending on flow. This makes them especially helpful for busy schedules, overnight use, or travel.
✔️ Lower Risk of Odor
Because menstrual blood isn’t exposed to air while inside the cup, there’s less odor compared with pads.
✔️ Chemical‑Free
Most cups are made from medical‑grade silicone, rubber, or TPE, and do not contain bleaches, fragrances, or absorbency gels.
Types of Menstrual Cups
Although all cups share the same basic function, there are variations to suit different needs:
1. Silicone Cups
- Most popular option
- Soft, flexible, and hypoallergenic
- Ideal for beginners and most users
2. Rubber (Latex) Cups
- Slightly firmer than silicone
- Not suitable for those with latex allergies
3. TPE (Thermoplastic Elastomer) Cups
- Softer and moldable with body heat
- Good for users who want an easier‑to‑insert or very soft option
4. Shape Variations
- Bell‑shaped: Most common; fits a wide range of anatomies
- V‑shaped: Sometimes preferred by users with a high cervix
- Shorter cups: Better for users with a low cervix or a shorter vaginal canal
5. Firmness Options
A firmer cup “pops open” easily but may be felt more by sensitive users. Softer cups are more comfortable but may require more adjustment to ensure they fully open.
When to Replace a Menstrual Cup
The lifespan of a cup depends on its material, brand, and how well it’s cared for. In general:
Replace your cup if:
- There are tears, cracks, or thinning in the silicone
- The cup becomes sticky, tacky, or develops a texture change
- There is persistent staining or odor that doesn’t resolve with cleaning
- The rim becomes misshapen
- The manufacturer recommends replacement (usually every 2–5 years, some up to 10 years)
Routine Replacement Timeline
- Medical‑grade silicone cups: 2–10 years
- TPE cups: 1–5 years
- Latex cups: Often 1–3 years
Proper care—such as boiling between cycles, using mild soap, and avoiding harsh cleansers—extends the lifespan.
