From 1936 to 1945, the Women’s Field Army, hereafter the WFA, educated women in the US on the early symptoms, prevention, and treatment of reproductive cancers. The WFA was a women-led volunteer organization and a branch of, what was then called, the American Society for the Control of Cancer, or ASCC. The WFA, headquartered in New York City, New York, recruited hundreds of thousands of women volunteers across the country. They distributed pamphlets, showed movies, and participated in other grassroots efforts to foster an understanding of reproductive cancers, namely breast and cervical cancer, among other women. The Women’s Field Army aided in reducing the number of cancer-related deaths by spreading cancer prevention awareness and teaching women about their reproductive health and the early detection of cancer, which was one of the first widespread educational resources about reproductive cancers for women.

In 2008, Celeste Mergens founded the organization Days for Girls to address obstacles impeding women’s and girls’ access to sustainable hygiene and health education by enlisting volunteers around the world to construct reusable menstrual hygiene products for girls in low-income countries. Mergens founded Days for Girls in the US in 2008 after learning that an orphanage she was working with in Kenya did not have resources for girls to manage their menstrual cycles. She provided those girls with reusable sanitary pads, and later that year, she decided to provide Days for Girls Kits, or DfG Kits, that volunteers from around the world made for women and girls in parts of the world lacking access to menstrual hygiene products. By 2012, Mergens launched chapters across the United States to allow volunteers to hand-sew the DfG Kits, and by 2019, the organization expanded to include chapters in Zimbabwe, Ghana, and Uganda. Days for Girls provides women and girls with education and resources necessary to manage menstruation, which can help reduce the instances of absenteeism for girls in schools and reduce the risk of contracting infectious diseases.

The International Eugenics Congresses consisted of three scientific meetings held in London, England, in 1912 and at the American Museum of Natural History in New York City, New York, in 1921 and 1932. Leonard Darwin, son of Charles Darwin, Henry Fairfield Osborn, the President of the American Museum of Natural History, and Charles Benedict Davenport, founder of the Eugenics Record Office at Cold Spring Harbor Laboratory in New York City presided over the Congresses. Scientists presented research in genetics and shared ideas for putting eugenics into practice, such as preventing people they considered inferior from reproducing through forced sterilization. The three International Eugenics Congresses increased scientific and public support of the eugenics movement in the early twentieth century, and established organizations to pursue eugenics agendas that contributed to the forced sterilization of hundreds of thousands of people in the US and Nazi Germany.

In 2006, the United States branch of Merck & Co. received FDA approval for Gardasil, a human papillomavirus, or HPV, vaccine that protects against HPV and the cervical cancer that can come with it. In 1891, George F. Merck founded the US branch of the company to distribute chemicals with high purity for use in research, in New York City, New York, and other areas nearby. HPV is a common sexually transmitted infection that can cause genital warts, regular skin warts, cervical cancer, and other cancers. Since 2016, Gardasil has been the only HPV vaccine in use in the US and over people received 28 million doses in the country between 2014 and 2017, reducing people’s chances of contracting cancer.

No-scalpel vasectomy, or NSV or keyhole vasectomy, is a surgical method of sterilization that involves puncturing the skin of the scrotum to access the vas deferens, a tube that carries spermatozoa, or sperm, from the testes to the penis. The surgeon performing the procedure blocks the flow of sperm through the vas deferens, sterilizing the patient. NSV is a less invasive procedure, as it does not use a scalpel to make a deep cut on sensitive scrotal tissue. Typically, urologists perform NSV with the purpose of rendering the patient sterile while not altering other functions of the testes, scrotum, and penis. Li Shunqiang developed the technique in China in 1974 as a less invasive method of vasectomy for male patients. Li’s development of NSV provided an alternative method to vasectomies that rely on making incisions into the scrotum with a blade. NSV gained wide use as a sterilization technique, providing a path for males to take greater responsibility for contraception and family planning.

In the United States, most people are assigned both a biological sex and gender at birth based on their chromosomes and reproductive organs. However, there is an important distinction between biological sex and gender. Biological sex, such as male or female, commonly refers to physical characteristics. Gender refers to the socially constructed roles, behaviors, and actions people take on, usually in relation to expectations of masculinity or femininity. As of 2022, there is disagreement over the relation between sex and gender. People’s biological sex and gender greatly influence the way they understand themselves, as well as how others treat them and how they interact with society. Moreover, some people’s gender differs from what they were assigned at birth, and they face discrimination, harassment, and violence. Evolving understandings of gender and sex in the US have created more ways for people to live and express their gender identities.

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.

The National Association for Down Syndrome, or NADS, is an organization that was founded in 1960 by Kathryn McGee in Chicago, Illinois, to support people with Down syndrome and their families in improving their quality of life. Originally named the Mongoloid Developmental Council, NADS is one of the oldest organizations serving people with Down syndrome and their families in the United States. According to NADS, Down syndrome is a genetic condition that occurs in one in every seven hundred ninety-two people and that causes delays in physical and intellectual development. Members of NADS work to provide information, resources, and access to services and programs for families with Down syndrome, educate the public, address social policy issues and challenges, and facilitate advocacy efforts within the Down syndrome community. For over sixty years, NADS has helped support individuals born with Down syndrome, one of the most common genetic disorders, in the US to find acceptance, develop their capabilities, and work toward independence.

In 1990, the United States Congress passed the Americans with Disabilities Act, or the ADA, which prohibits discrimination against people with disabilities by employers, governments, or public accommodations. Following gains made during the civil rights movements of the 1900s, people with disabilities sought similar anti-discrimination legislation. The ADA was the culmination of decades of protest and advocacy from the disability rights movement. After the ADA, federal law protected people with an impairment that limited major life functions like sight or mobility from discrimination. The ADA changed the lives of millions of Americans with disabilities by expanding the opportunities they had to work, travel, and participate in their communities legally protected from discrimination.

The Mother's Health Clinic opened in Phoenix, Arizona, in 1937 and provided women in central Arizona with contraception and family planning resources. A group of wealthy philanthropic Phoenix women founded the clinic under the guidance of birth control activist Margaret Sanger. The clinic was the second birth control clinic to open in Arizona and the first to serve the central and northern Arizona residents. In 1942, the clinic affiliated with the national organization Planned Parenthood Federation of America and eventually formed the Planned Parenthood of Central and Northern Arizona. The Mother's Health Clinic provided Arizona women with contraception and family planning at a time when birth control was not widely accepted or available.
