For women seeking an abortion, finding a doctor willing to offer one is easier said than done. Ninety-seven percent of OB-GYNs have encountered patients wanting an abortion, but only 14% of the doctors perform them, according to a study published in the journal Obstetrics and Gynecology. That finding suggests a smaller percentage of OB-GYNs may be offering abortion services than previous studies have estimated. Access to abortion has become more limited over the past few decades, the researchers write. Another recent study found that in 2008, 87% of U.S. counties (where 35% of reproductive-aged women live) didn't have any abortion providers. Since 1996, however, all OB-GYN residents have been required to learn how to perform the procedure. This year, states have passed at least 80 new abortion restrictions -- double the previous annual record of 34 seen in 2005, and more than triple 2010's 23 changes. Religious affiliation turns out to be a fairly significant indicator of whether a doctor will or won't provide abortions. Forty percent of Jewish doctors say yes, compared with 1% of evangelicals. Nine percent of Roman Catholics or members of Eastern Orthodox churches were likely to perform abortions. Among OB-BYNs, 10% of non-evangelical Protestants, 20% of Hindus and 27% of doctors who said they had no religious affiliation said they offer abortion services.
