Who is Natural Cycles most suitable for?

Many women choose to use the Pill and other short or long-acting methods of contraception and are happy with their choice. However, there are a number of women who decide to stop hormonal methods for a variety of reasons. These women are potential candidates for Natural Cycles.

  • Women using Natural Cycles should be at least 18 years old. Today the typical woman using Natural Cycles is 30 years old on average, has a daily routine and is in a stable relationship.
  • Women using Natural Cycles and their partners should be comfortable using protection (condoms) on red days and she should be willing to measure her temperature in the morning.
  • Women using Natural Cycles tend to be health conscious, are interested in learning about their cycle and becoming more aware of it and have a desire to be more in tune with their body.
  • Natural Cycles is also a suitable option for women who are considering a pregnancy within the next few years.

Evidence shows that a woman who, following consultation with her HCP, has actively chosen a method of contraception and is satisfied with it, is more likely to use it consistently and correctly. On the other hand, women using a method which is not in line with their actual preferences may be less likely to adhere to it or may discontinue the method.¹

Providing information for women and their HCPs and increasing the choice of options lie at the core of our company’s mission so that every woman and her partner can find a method best suited to their needs.

Who is Natural Cycles less suitable for?

Natural Cycles is an effective contraceptive for women with fairly regular and ovulatory menstrual cycles. It may be less suitable for women with irregular menstrual cycles, since predicting her fertile days is more difficult and the number of red days will be higher.

Natural Cycles does not protect against STIs, therefore the app is generally recommended for women in stable relationships.
