In 2003, the Texas state legislature passed the Woman’s Right to Know Act, hereafter the Act, as Chapter 171 of the state’s Health and Safety Code. The Act sets requirements that physicians must follow during the informed consent process for abortion, or a medical procedure to terminate pregnancy, in Texas. Lawmakers amended the Act and added several additional regulations that restrict access to abortion in 2011, 2013, 2015, and 2017. For instance, the Act requires that physicians perform abortions after sixteen weeks of pregnancy in ambulatory surgical centers or hospitals and states that physicians must perform an ultrasound to view images, called sonograms, of a developing fetus inside a woman’s uterus before a woman may receive an abortion. The Act further requires practitioners and clinics to offer state-developed informational materials to women who seek an abortion. The Act placed several restrictions on abortion care in Texas, making it more difficult for women to access safe and legal abortion care, which opponents have challenged in courts.

Harvey Karman was an abortionist, inventor, and activist for safe abortion techniques in the US during the twentieth century. Karman developed the Karman cannula, a flexible soft tube used for vacuum aspiration abortions. Karman traveled extensively throughout the US to educate healthcare providers on how to administer safe abortions. He also traveled to Bangladesh, India, China, and other developing nations to promote safe and simple abortion techniques that anyone could perform without previous medical training. As of 2017, Karman’s abortion technique and cannula continue to be widely used throughout the world for terminating early pregnancies. Karman challenged laws prohibiting abortion in the US prior to 1973 and worked to create methods for abortion that were safer, less expensive, and easier to administer than previous abortion techniques.
