Poland's government is facing criticism over a new provision that requires doctors to record each pregnancy in the country.
Opposition MPs have labelled the medical data list as a "pregnancy register" and an infringement of women's rights, aimed to detect possible illegal abortions.
Poland has placed a near-total ban on abortion and activists are concerned that women will face unprecedented surveillance from the ruling conservative party.
Under a strict 2020 legal reform, Polish women can only seek an abortion if there is a serious risk to the mother's health or if the pregnancy results from rape or incest.
The government register was also denounced by Poland's opposition leader and former EU Council President Donald Tusk.
