  • Have problems with broken condoms
  • Are concerned about sexually transmitted infections
  • Require guidance on contraception

The use of barrier methods together with other types of contraception can work for some people.

Contraception provides an opportunity for planning the timing of pregnancies. Many people favor the use of non-hormonal contraceptives due to their lack of hormones, which may pose side effects.
