Turkish President Recep Tayyip Erdogan has said women cannot be treated as equal to men, and has accused feminists of rejecting motherhood.
"You cannot put women and men on an equal footing," he told a meeting in Istanbul. "It is against nature."
He also said feminists did not grasp the importance of motherhood in Islam.
His comments often seek to appeal to his pious core supporters, says the BBC's Mark Lowen in Istanbul, but they anger more liberal voters.
Turks who have more secular views argue that the government's social policies are taking the country in a dangerous direction, our correspondent says.
Mr Erdogan has previously urged women to have three children, and has lashed out against abortion and birth by Caesarean section.
'Delicate nature'
His latest remarks were delivered at a women's conference in Istanbul.
"In the workplace, you cannot treat a man and a pregnant woman in the same way," Mr Erdogan said, according to the Anatolia news agency.
Women cannot do all the work done by men, he added, because it was against their "delicate nature".
"Our religion regards motherhood very highly," he said. "Feminists don't understand that, they reject motherhood."
He said women needed equal respect rather than equality.
Mr Erdogan also told the Istanbul meeting that justice was the solution to most of the world's issues - including racism, anti-Semitism, and "women's problems".
The Turkish leader often courts controversy with his statements.
Earlier this month, he claimed that Muslims had discovered the Americas more than 300 years before Christopher Colombus.
In his 11 years as prime minister, Mr Erdogan became a crucial player in regional politics.
However, his reputation has suffered recently over the crisis in Syria, and accusations of authoritarianism.
Erdogan's crazy train seems to be running at full steam.
