I don't suppose you can be fussed to supply a source for that claim?

In 1857, the AMA took aim at unregulated abortion providers with a letter-writing campaign pushing state lawmakers to ban the practice. To make their case, they asserted that there was a medical consensus that life begins at conception, rather than at quickening.
The campaign succeeded. At least 40 anti-abortion laws went on the books between 1860 and 1880.
And yet some doctors continued to perform abortions in the late 19th and early 20th centuries. By then, abortion was illegal in almost all states and territories, but during the Depression era, “doctors could see why women wouldn’t want a child,” and many would perform them anyway, Fissell says. In the 1920s and through the 1930s, many cities had physicians who specialized in abortions, and other doctors would refer patients to them “off book.”
That leniency faded with the end of World War II. “All across America, it’s very much about gender roles, and women are supposed to be in the home, having babies,” Fissell says. This shift in the 1940s and ’50s meant that more doctors were prosecuted for performing abortions, which drove the practice underground and into less skilled hands. In the 1950s and 1960s, up to 1.2 million illegal abortions were performed each year in the U.S., according to
the Guttmacher Institute. In 1965, 17% of reported deaths attributed to pregnancy and childbirth were associated with illegal abortion.
