Birth Control Methods

Internal Condoms

FC2® Internal Condom (only FDA approved in the US)
About

The internal condom, also known as FC2, is a pouch made from nitrile that is inserted into the vagina or anus before sex. It acts as a barrier to prevent sperm from reaching an egg and protects against sexually transmitted infections (STIs). Unlike external condoms, part of the FC2 stays outside the vagina, covering some of the external genitalia, which offers additional protection against STIs transmitted through skin contact.

Mechanism of Action

Internal condoms work to prevent pregnancy through these key actions:

  1. Barrier creation: The internal condom acts as a barrier that prevents sperm from entering the uterus.
  2. Semen collection: It collects semen when a man ejaculates, keeping the sperm contained within the condom.
  3. Prevents egg fertilization: By trapping the sperm, it prevents them from progressing to fertilize an egg.

Using internal condoms has several benefits besides preventing pregnancy, and here’s how they can be helpful:

  • Provides protection against STIs, including HIV.
  • Covers part of the vulva, reducing the risk of STIs spread through skin-to-skin contact.
  • Hormone-free, suitable for those who prefer or need to avoid hormonal contraceptives.

Internal condoms are a barrier method that work immediately. Some individuals choose to combine condoms with other forms of birth control for increased protection such as the pill, implant, IUD, or injection.

Potential Side Effects and Concerns

When using internal condoms, there are some potential side effects and concerns to keep in mind:

  • Although the internal condom is effective and offers dual protection (both contraceptive and against STIs), it requires a prescription and is not as readily available as external condoms.
  • It cannot be used with other intravaginal devices like the vaginal ring, diaphragm, or cervical cap.
  • Vaginal or penile irritation.
  • Reduced sensation during intercourse for some users.
  • Noise during use, which some find distracting.
Who Should Not Use This?

Internal condoms should not be used by:

  • Individuals allergic to nitrile.
  • Those who find it difficult to insert or use correctly, as improper use reduces its effectiveness.
  • Anyone using an external condom simultaneously, as this can increase the risk of tearing.
