From 1945 to 1973, it is estimated that up to 4 million parents in the United States had children placed for adoption, with 2 million during the 1960s alone. [2] Annual numbers for non-relative adoptions increased from an estimated 33,800 in 1951 to a peak of 89,200 in 1970, then quickly declined to an estimated 47,700 in 1975.

Now, an underground art movement led by artist Sophia Wallace is emerging across the globe to challenge the lies, question the myths and rewrite the rules around sex and the female body.
In one study, researchers gave pregnant women between 100 and 200 microcuries (3.7 and 7.4 MBq) of iodine-131, and later performed abortions to study the women's embryos in an attempt to discover at what stage, and to what extent, radioactive iodine crosses the placental barrier. [67]
