> Sterilization was most frequently recommended by physicians because of a pervasive belief that Puerto Ricans and the poor were not intelligent enough to use other forms of contraception. Physicians and hospitals alike also implemented hospital policy to encourage sterilization, with some hospitals refusing to admit healthy pregnant women for delivery unless they consented to be sterilized. This has been best documented at Presbyterian Hospital, where the unofficial policy for a time was to refuse admittance for delivery to women who already had three living children unless she consented to sterilization. There is additional evidence that true informed consent was not obtained from patients before they underwent sterilization, if consent was solicited at all.
