Abortion
Abortion was a medical procedure in which a fetus was terminated within the mother's womb.

A 2003 news article on George W. Bush's State of the Union Address, which among other things adressed his plans to limit abortion, was stored in Crewman ' 31st century database. ()

In 2153, the Triannon female Indava asked Doctor Phlox to terminate her pregnancy, as she did not want her child to become a soldier in D'Jamat's war. Phlox did not perform the procedure because he did not finish "studying their physiology." ()

In 2365, Deanna Troi became pregnant from a non-corporeal lifeform. Lieutenant Worf proposed aborting the fetus as it may have been a threat to the crew. Data suggested that if it was not allowed to develop, it couldn't be studied, to which Worf replied that it could still be analyzed in a laboratory whether it lived or not. William T. Riker then asked Dr. Katherine Pulaski whether an abortion would carry any health risks for Troi. Troi refused to have an abortion and carried the child to term, which lasted just over a day. ()

In 2368, Geordi La Forge commented to Hannah Bates that had he been conceived on Genome colony, he would have been terminated as a fertilized  due to his blindness. ()
