Birth control

What is birth control?

Birth control is a collective name for all methods and means that are used to prevent pregnancy. The drugs used for birth control are also called contraceptives.

How does contraception work?

The different methods of contraception prevent pregnancy from occurring by ensuring that an egg cannot be fertilized by a sperm. This can be done by:

  • prevent the production of egg cells in women or sperm in men: hormonal contraception;
  • to prevent sperm from reaching the fallopian tubes through the uterus by introducing a copper or hormone coil into the uterus: intrauterine contraception
  • by refraining from intercourse during the fertile days of women: the “natural” methods of prevent pregnancy;
  • by preventing sperm and egg from reaching each other during sexual intercourse: the barrier methods and the sterilization.

How reliable is birth control?

Without birth control, the chance of becoming pregnant within a year is 80%.
The most reliable methods of contraception are those methods, whereby the person applying the method cannot influence the effect. This is the case with sterilization, the copper IUDs, the hormone IUD and the hormone rod. If one of these methods is used, the chance of pregnancy is less than 1 in 200 per year.
This reliability can also be achieved with careful application of all other hormonal methods of contraception. In practice, the chance of becoming pregnant appears to be slightly higher, especially as a pill is regularly forgotten or a patient fails to get a new injection on time.
The least reliable are the natural methods of birth control and the use of barrier means. The accuracy of applying these methods and means is particularly important here.
