Contraceptive app reported after unwanted pregnancies

5:01 min

A Swedish smartphone app officially certified as a contraceptive has been reported to the Medical Products Agency after 37 users received unwanted pregnancies.

Stockholm's southern hospital filed the report after midwives found that 37 out of over 600 women seeking abortion in a four month period said they had used the contraceptive app.

I am concerned. It's a very good device if you would like to predict your capabilities when you want to get pregnant. But if you really want to avoid pregnancy, then I think you should go for another method, such as a coil."

Gynecologist and university lecturer Lena Marions told Radio Sweden that she had no problem with the method used in the app, but that it was difficult for some women to strictly follow the guidelines on a daily basis.

Last year the app won approval to be used as a contraceptive device in the EU after a German certification and inspection team gave it the green light.

The company itself, Natural Cycles, based in Stockholm, issued a statement, Thursday.

- No contraception is 100% and unwanted pregnancies is an unfortunate risk with any contraception. Natural Cycles has a Pearl Index of 7, which means it is 93% effective at typical use, which we also communicate.

- 37 unwanted pregnancies out of the 668 mentioned in this study at SÖS is not surprising from a scientific perspective. 37 out of 668 means that 5,5% women state they have used Natural Cycles when having an unwanted pregnancy, which actually is in line with what we communicate as the risk of unwanted pregnancy with typical use, and which is comparable to other types of contraception.
