A quiet shift is taking place in how women obtain birth control. A growing assortment of new apps and websites now make it possible to get prescription contraceptives without going to the doctor.

The development has potential to be more than just a convenience for women already on birth control. Public health experts hope it will encourage more to start, or restart, using contraception and help reduce the country’s stubbornly high rate of unintended pregnancies, as well as the rate of abortions.

And as apps and websites, rather than legislative proposals or taxpayer-funded programs, the new services have so far sprung up beneath the political radar and grown through word of mouth, with little of the furor that has come to be expected in issues involving reproductive health.

At least six digital ventures, by private companies and nonprofits, including Planned Parenthood, now provide prescriptions written by clinicians after women answer questions about their health online or by video. All prescribe birth control pills, and some prescribe patches, rings and morning-after pills. Some ship contraceptives directly to women’s doors.
