Effective and safe contraception protects women against physical, psychological and socioeconomic consequences of unwanted pregnancy and against the major decision of induced abortion. In the Netherlands, more than 95 % of contraceptive advice and contraception is provided by general practitioners. In addition, in sexual health centres (GGD-Sense), young people under the age of 25 years can get contraceptive advice free of charge. Midwives are involved in discussing or providing contraception. Gynaecologists are specialised in contraception for women with specific medical conditions or needs, and instrumental or surgical methods. All health workers should have sufficient knowledge about the advantages and disadvantages of the available contraceptive methods. Health workers should provide information on the different contraceptive methods to the individual woman. Above all else, the health worker should take care that this information is objective, understandable and includes non-contraceptive benefits, such as cycle regulation and prevention of sexually transmitted diseases. Choices will be made in accordance with the person’s wishes, sexual lifestyle, possibilities, life course and medical prerequisites. Effective and safe contraception will be different for everyone.

A long-acting contraceptive method with immediate return of fertility after stopping, such as Implanon, hormone-IUD and copper-IUD. LARCs do not require frequent office or pharmacy visits and do not depend on user compliance for effectiveness.
Monophasic combinations
In monophasic COCs all tablets have the same fixed dose of oestrogen and progestin
Pearl Index
The number of unintended pregnancies divided by the number of women years of exposure to the risk of pregnancy while using the method. A Pearl Index of 2 means that of 100 women who use the method during 1 year, 2 women get pregnant (or 2 % of the users per year).
Perfect use
Refers to use of the method as intended and covering all acts of exposure to pregnancy
Second generation COCs
In second generation COCs all tablets contain an oestrogen and a progestin synthesised later than the original progestins in the pill (first generation).
Sexual arousability
Defined as the receptivity of a person to sexual stimuli.
Total fertility rate (TFR)
Represents the average number of children that would be born per woman if all women were to live to the end of their childbearing years and would bear children in accordance with current age-specific fertility rates. Without immigration, population growth stops at a TFR of 2.1.
Typical use
A measure of how effective methods are when used by a group of people under study actually using them.
