Vasectomy is one of few widely available methods of contraception for people with male reproductive systems aside from condoms, abstinence, and the withdrawal method, and it is the only one of those options that can be permanent (Amory 2016). The procedure’s prominence has led me to investigate the history of vasectomy and particularly the evolution in vasectomy technique over time. Since its introduction in the late nineteenth century, the procedure has had a variety of impacts on many people across the world. In this research project, I have sought to analyze what the technical evolution of vasectomy reveals about the changing priorities of the medical systems that use it. In particular, I point to ways the eugenics movement’s attempts to control individual reproduction have led to both vasectomy’s efficacy and its restrictiveness.

The NuvaRing is a self-administered hormonal contraceptive device in the form of a flexible plastic ring that is inserted into the vagina. It releases the hormones etonogestrel and ethinylestradiol, which are synthetic forms of the female reproductive hormones progesterone and estrogen, respectively. The pharmaceutical company Organon first made NuvaRing in the Netherlands in 1980s. The Netherlands first approved it for use in February of 2001, and the United States did the same in October of that year. To insert the NuvaRing, a user pinches the ring together to compress it and inserts it into the vaginal canal, where its exact placement does not matter. The NuvaRing stays in the vagina for three weeks, after which the user removes it for one week. During the week following removal, the user experiences bleeding similar to a menstrual period. The NuvaRing was one of the first monthly vaginal rings used for contraception, and it provides a self-administered method of birth control, which can be more accessible for some users than taking a birth control pill every day.

Harry Clay Sharp was a surgeon who performed one of the first recorded vasectomies with the purpose of sterilizing a patient. Sterilization is the practice that makes a person unable to reproduce, and vasectomy accomplishes that by severing the vasa deferentia, the sperm-carrying tubes in the male reproductive system. Historically, sterilization procedures have varied in techniques, goals, and risks, but Sharp’s method of vasectomy allowed restriction of a patient’s reproductive functions without significantly affecting other bodily functions. Historians have associated Sharp’s use of the procedure, primarily on prison inmates, with eugenics, a movement with the goal of bettering humans via selective reproductive practices. With vasectomy, Sharp was able to sterilize people whom he did not deem fit to reproduce. Beyond simply pushing forward a new surgical method of sterilization, Sharp’s political advocacy led to the use of his technique as a method of eugenicist control over human reproduction, especially in Indiana.
