Introduction

Birth control refers to deliberate measures taken to prevent fertilisation, thereby avoiding unwanted pregnancies. Contraception is the general term for methods used to achieve this.

India's population crossed 1.2 billion by May 2011, making population control a national priority. The Government of India launched the Reproductive and Child Health (RCH) programme in 1997 to address population growth and reproductive health concerns.

Additional measures adopted by the Government of India include:

  • Statutory minimum marriage age: 18 years for females, 21 years for males
  • The popular slogan: 'Hum Do Hamare Do' (We Two, Our Two)
  • Incentives for small families and awareness drives

Note: India's first family planning programme was launched in 1951, making it one of the earliest nations to do so.

3 Effective High success rate in preventing unwanted pregnancy
4 Reversible Fertility should be restored after stopping the method
5 No/minimal side effects Should not cause long-term harm to the body
