Some U.S. women will receive abortion pills by mail as part of a study on whether these abortions, which don't involve going to an abortion clinic and are referred to as "telabortions," can be done safely.

The study is being conducted with women in four states, Hawaii, New York, Oregon and Washington. So far, 12 women have participated in the study, and 11 did not have any complications from taking the medicine, while one did not take the pills, according to the New York Times.

Currently, abortion pills cannot be sold in pharmacies in the United States, and are typically available only at abortion clinics and hospitals, the Times said. ['Abortion Pill' Gets New Label: 5 Things to Know About Mifepristone]

In the new study, women first consult with a doctor via an online video service. Then they go to a facility near them where they can undergo a few tests, including a blood test an ultrasound. Next, the researchers send a package will the pills in the mail via overnight delivery, the Times said. After taking the pills, the women will undergo some additional tests and have another video talk with the doctor.

Advocates of increasing access to medical services for women hope the findings could expand access to abortion services, the Times said. There are currently five states that each have only a single abortion clinic.

Some states allow women to consult with a doctor online to get an abortion, but the women must still go to a specific clinic to get the pills.

The "abortion pills" used in these procedures refers to two medications, mifepristone and misoprostol, which are taken to end pregnancy. Women can only take the pills to end a pregnancy during the first 10 weeks of pregnancy. Serious side effects are rare, but can include infection and hemorrhage. These occur in less than 0.5 percent of people who take the mifepristone, according to the Food and Drug Administration.
