CHICAGO: The governor of Oklahoma is considering tough new abortion bills that would allow doctors to withhold test results showing foetal defects and require women to answer intrusive questions.

The results of the questionnaires would be posted online.

Women would also be required to have a vaginal ultrasound and listen to a detailed description of the embryo or foetus in a third bill passed by the legislature on Monday.

The requirements would be among the most ''extreme'' in the US and were similar to those struck down by a state court as unconstitutional earlier this year, the Centre for Reproductive Rights said on Tuesday.

''Despite the prospect and cost of additional legal challenges, the legislature is determined to severely limit women's ability to get an abortion in the state, approving laws with clear constitutional flaws and with absolute disregard for women's rights and health,'' the centre said in a statement urging a veto of the bills.
