The number of abortions in South Dakota fell last year.

An annual state Health Department report shows that doctors did 748 abortions in 2006 -- a reduction of 7 percent from the 805 that were done in 2005.

Both abortion foes and abortion-rights supporters attribute the drop to efforts to reduce unplanned pregnancies.

An official of the Alpha Center in Sioux Falls says its emphasis on abstinence from sex has helped reduce pregnancies and abortions.

An official of Planned Parenthood in Sioux Falls says sex education -- with an emphasis on birth control -- has reduced the number of abortions in South Dakota.
