What is Orchid?

Orchid is the app that helps you take control of your reproductive health. The app guides you through a set of questions about your reproductive preferences and presents you with personalised results; a reproductive preference group, your likelihood of pregnancy in the next year and links to helpful and trustworthy resources.

Why Orchid?

We named the app Orchid as the word has links to both male and female reproductive systems.

Pregnancy prediction

The predicted probability of pregnancy is generated based on a model created using data from the P3 Study.

A person’s ‘desire to avoid pregnancy’ is measured using the DAP Scale (a set of 14 questions) which gives a score from zero – someone who wants to become pregnant – to four – someone who really doesn’t want to become pregnant. This score is then is combined with the woman’s age and number of children to refine the predicted probability of pregnancy.

This model was developed using data from people from the UK, who self-reported as being female and were from a range of backgrounds.  

The model includes everyone, regardless of whether they are having heterosexual sex or are on contraception. It is important to bear in mind that these are predicted probabilities and not guarantees.

If you are a female having vaginal sex with a male partner and do not wish to become pregnant, it is important that you consider you contraceptive options. Conversely, if you do wish to become pregnant you can improve your chances by addressing any health issues before pregnancy and having sex every few days across your cycle.
