Dot Efficacy Study

The Dot study is a prospective efficacy study being conducted by Georgetown University's Institute for Reproductive Health (IRH). The purpose of the study is to determine how effective the Dot Android app, developed by Cycle Technologies, is at preventing pregnancy over time.

The study will enroll 1200 women and follow them for 13 menstrual cycles (or about one year). Women who enroll in the study will provide information to IRH researchers about their menstrual cycles, their sexual activity, and how they are using the information they get from Dot to make decisions about their fertility. 

+ About Dot™ the App

Dynamic Optimal Timing, or Dot™, is a new method of family planning that can be used to plan or prevent pregnancy entirely through a smartphone.

The scientifically-based Dot app uses an algorithm to accurately predict a woman’s pregnancy risk for each day of her cycle, flagging high and low fertility days of her cycle. Dot applies information from past studies and essentially “learns” a woman's cycles as she enters her period start dates.

This creates a tailored fertility window specific to a particular woman and makes it clear how she should use this information to achieve her reproductive goals.

Women who have cycles between 20-40 days long can use Dot to make informed estimates about their future fertility, just by entering their period start dates.

+ What Makes Dot Unique?

While there are many fertility awareness methods that can be effectively used to plan or prevent pregnancy, they usually require women receive intensive training from an experienced provider on how to interpret and act on their fertility signs (such as their temperature or cervical mucus). Dot is different because it is simple, yet effective. Women only need to enter their period start date to use the method. They don’t need to interpret any fertility signs – the app will tell them when they are fertile or not fertile.

Dot is, importantly, a user-centered method. Women don’t need to visit a healthcare provider or even a pharmacy to access or use the method. In 2020, an estimated 75% of the world’s population will have access to a smartphone. Dot attempts to harness the power of this expanding technology to expand women’s family planning options.

Dot has great potential to provide women with a new family planning option that has a foundation of research and has been rigorously tested so that women can accurately plan or avoid pregnancy.
