Section 1. of the bill, entitled "Unsexing of Criminals" addressed the "managing officer of each public institution in the state," entrusted with the custody or care of people who had been deemed socially problematic, defined as people with sexually transmitted infections, like syphilis, as well as people who have been confined due to alcohol and drug charges, and people who were being categorized as intellectually deficient.
These managing officers, along with the parole board, were tasked with considering if it would be "improper or inadvisable" for detained people to reproduce and if so, tasked them with sterilization (§§ 2600-o5-2600-p. PREVENTION OF PROCREATION OF CRIMINALS. Tit. XII, Ch. 19-B.). It also mandated sterilization for "twice convicted felons and any woman convicted even once of prostitution" (Drake 356).
This legislation was repealed soon after it was passed because of its unconstitutional use of sterilization as punishment. Subsequent versions did not mandate sterilization based on criminal record, instead opting to focus on reviewer opinions about the "best interests of the patient and society." (Drake 362) The third version of the legislation passed in 1913 and remained in effect until it was repealed in 1979 (67GA, ch 77, §1).
The revised bill established an official Board of Eugenics that also included the managing officer and surgical superintendent of each institution and these boards were the mechanism for evaluating and approving sterilizations (§2437-cl, Ch 114-C1). The formation of the Board of Eugenics established a process with a paper trail that now attests that the Iowa Board of Eugenics approved and oversaw the sterilization of 1,910 people deemed “unfit” to reproduce between 1934-1976. The state legislature abolished the BoE in 1977 and the law under which it operated was repealed two years later.
