London, England (LifeNews.com) -- A Princeton University says women are not using birth control pills correctly and the misuse is resulting in pregnancies and abortions that wouldn't otherwise occur. Professor James Trussell made the claim before a conference sponsored by the British Pregnancy Advisory Service abortion business.

Trussell says about 8 percent of women who use the birth control pill become pregnant annually and get abortions because they don't take the pills faithfully.

He also said the morning after pill is not effective in reducing pregnancies and abortions because it is not used widely enough.

According to a London Times report, Trussell said women should be encouraged to use implants or intrauterine devices (IUDs) that don't rely on women remembering to take a pill to prevent pregnancy.

“The Pill is an outdated method because it does not work well enough. It is very difficult for ordinary women to take a pill every single day," the Princeton professor said, according to the Times.

"The beauty of the implant or the IUD is that you can forget about them," he added.

Trussell said if seven percent of British women switched to an IUD he thinks there will be 73,000 fewer unintended pregnancies and fewer abortions as well.

However, pro-life advocates have criticized the use of those devices, as they have the morning after pill, because it can cause abortions in some circumstances by preventing the unborn child from implanting into the mother's uterus to continue growing and developing.

Though Trussell suggests greater use of the morning after pill would also reduce pregnancies and abortions, that hasn't happened.

The number of abortions in Scotland has risen for the third straight year despite a heavy push for women to use the morning after pill. Abortion advocates claimed selling the Plan B drug over the counter would reduce abortion rates, but the new figures reveal the number of abortions rising again.

Abortions in Scotland rose four percent according to a report from the British national health Service and now number 13,703.

That increase came after NHS reported 13,081 abortions in 2006, up from 12,603 the previous year -- an increase of nearly 3.8 percent.
