World Contraception Day (WCD) is annually observed on September 26. This day was observed for the first time in 2007, when it was initiated by coalition of 16 international family planning organizations. 
All international non-governmental organizations, that support observance of World Contraception Day, have a vision of a world where every pregnancy is wanted. Observation of this day raises public awareness of the means of contraception.
WCD’s mission is to improve awareness of contraception and to enable young people to make informed choices on their sexual and reproductive health.
Benefits of family planning / contraception (World Health Organization)
- Promotion of family planning – and ensuring access to preferred contraceptive methods for women and couples – is essential to securing the well-being and autonomy of women, while supporting the health and development of communities.
- Preventing pregnancy-related health risks in women: A woman’s ability to choose if and when to become pregnant has a direct impact on her health and well-being. Family planning allows spacing of pregnancies and can delay pregnancies in young women at increased risk of health problems and death from early childbearing. It prevents unintended pregnancies, including those of older women who face increased risks related to pregnancy. Family planning enables women who wish to limit the size of their families to do so. Evidence suggests that women who have more than 4 children are at increased risk of maternal mortality.
By reducing rates of unintended pregnancies, family planning also reduces the need for unsafe abortion. - Reducing infant mortalityFamily planning can prevent closely spaced and ill-timed pregnancies and births, which contribute to some of the world’s highest infant mortality rates. Infants of mothers who die as a result of giving birth also have a greater risk of death and poor health.
- Helping to prevent HIV/AIDSFamily planning reduces the risk of unintended pregnancies among women living with HIV, resulting in fewer infected babies and orphans. In addition, male and female condoms provide dual protection against unintended pregnancies and against STIs including HIV.
- Empowering people and enhancing educationFamily planning enables people to make informed choices about their sexual and reproductive health. Family planning represents an opportunity for women to pursue additional education and participate in public life, including paid employment in non-family organizations. Additionally, having smaller families allows parents to invest more in each child. Children with fewer siblings tend to stay in school longer than those with many siblings.
- Reducing adolescent pregnancies
Pregnant adolescents are more likely to have preterm or low birth-weight babies. Babies born to adolescents have higher rates of neonatal mortality. Many adolescent girls who become pregnant have to leave school. This has long-term implications for them as individuals, their families and communities. - Slowing population growth
Family planning is key to slowing unsustainable population growth and the resulting negative impacts on the economy, environment, and national and regional development efforts.

| Combined contraceptive patch and combined contraceptive vaginal ring (CVR) | Continuously releases 2 hormones – a progestin and an estrogen- directly through the skin (patch) or from the ring. | Prevents the release of eggs from the ovaries (ovulation) | The patch and the CVR are new and research on effectiveness is limited. Effectiveness studies report that it may be more effective than the COCs, both as commonly and consistent or correct use. | The Patch and the CVR provide a comparable safety and pharmacokinetic profile to COCs with similar hormone formulations. | |
