Can you use a menstrual disc as birth control?

Published in Menstrual Health & Contraception 3 mins read

No, a menstrual disc cannot be used as birth control.

Menstrual discs are designed solely for the collection of menstrual fluid during your period and do not offer any protection against pregnancy or sexually transmitted infections (STIs).

Why Menstrual Discs Are Not Contraception

A common misconception might arise because menstrual discs are inserted into the body, similar to some birth control methods. However, their function is fundamentally different.

  • Purpose: Menstrual discs (and cups) are menstruation management products. Their design allows them to sit in the vaginal fornix, collecting menstrual blood. They do not contain spermicide, block sperm from reaching the egg, or alter hormonal levels to prevent ovulation.
  • No Contraceptive Properties: It is crucial to understand that menstrual discs are not contraceptive devices. This means they offer no barrier or chemical protection against conception.
  • STI Risk: Furthermore, using a menstrual disc does not protect against sexually transmitted infections. Sexual activity, including period sex, carries the same risks for pregnancy and STIs regardless of whether a menstrual disc is worn.

For clarity, consider the distinct functions of menstrual discs versus actual contraceptive methods:

Feature Menstrual Disc Contraceptive Methods
Primary Function Collect menstrual fluid during menstruation Prevent pregnancy; some also prevent STIs
Pregnancy Prevention None Highly effective (when used correctly)
STI Protection None Only barrier methods (like condoms) offer some STI protection
Mechanism Physical barrier to collect fluid Hormonal regulation, sperm blockage, or sperm inactivation
Examples Lumma Disc, Diva Disc, Flex Disc Oral contraceptives, condoms, IUDs, implants, diaphragms

Reliable Birth Control Methods

To prevent pregnancy, it's essential to use medically approved and effective birth control methods. These methods work through various mechanisms, such as:

  • Hormonal Methods:
    • Birth Control Pills: Taken daily to prevent ovulation.
    • Patches: Worn on the skin, releasing hormones.
    • Vaginal Rings: Inserted into the vagina, releasing hormones.
    • Injections (Depo-Provera): Administered every few months.
    • Implants (Nexplanon): Small rods inserted under the skin, releasing hormones.
  • Barrier Methods:
    • Condoms (Male and Female): Create a physical barrier to prevent sperm from reaching the egg; male condoms also offer significant STI protection.
    • Diaphragms/Cervical Caps: Inserted into the vagina before sex, used with spermicide.
    • Spermicide: Chemicals that immobilize or kill sperm, often used with barrier methods.
  • Intrauterine Devices (IUDs):
    • Hormonal IUDs: Release progestin to prevent pregnancy.
    • Copper IUDs: Non-hormonal, create an inflammatory reaction that is toxic to sperm and eggs.
  • Permanent Methods:
    • Tubal Ligation (for women): "Tying the tubes."
    • Vasectomy (for men): Cutting and sealing the vas deferens.
  • Natural Family Planning: Tracking fertility signs to avoid intercourse during fertile windows. This method requires significant commitment and training and is less effective than other methods.

For accurate information on choosing the right birth control method for you, consult reputable sources like Planned Parenthood or the Centers for Disease Control and Prevention (CDC).

In summary, while menstrual discs are a convenient tool for managing periods, they should never be relied upon for contraception or STI prevention. Always use dedicated birth control methods for those purposes.
