“Explaining Recent Declines in Adolescent Pregnancy in the United States: The Contribution of Abstinence and Improved Contraceptive Use” (2007), by John S. Santelli, Laura Duberstein Lindberg, Lawrence B. Finer, and Susheela Singh

In “Explaining Recent Declines in Adolescent Pregnancy in the United States: The Contribution of Abstinence and Improved Contraceptive Use,” hereafter “Explaining Recent Declines,” researchers John S. Santelli, Laura Duberstein Lindberg, Lawrence B. Finer, and Susheela Singh discuss what led to the major decline in US adolescent pregnancy rates from 1995 to 2002. Working with the Guttmacher Institute, a reproductive health research organization, they found that the decline in US adolescent pregnancy rates between 1995 and 2002 was primarily due to improved contraceptive use.

Bowen v. Kendrick (1988)

On 29 June 1988, in Bowen v. Kendrick, the US Supreme Court ruled in a five-to-four decision that the 1981 Adolescent Family Life Act, or AFLA, was constitutional. Under AFLA, the US government could distribute federal funding for abstinence-only sexual education programs, oftentimes given to groups with religious affiliations. As a federal taxpayer, Chan Kendrick challenged the constitutionality of AFLA, claiming it violated the separation of church and state.

Thesis: Publicly Funded Family Planning in Arizona, 1940–2017

Nearly seven decades ago, the US government established grants to the states for family planning and acknowledged the importance of enabling all women to plan and space their pregnancies, regardless of personal income. Since then, publicly-funded family planning services have empowered millions of women, men, and adolescents to achieve their childbearing goals. Despite the recognized importance of subsidized family planning, services remain funded in a piecemeal fashion.

Thesis: Growing Human Organs in Animals: Interspecies Blastocyst Complementation as a Potential Solution for Organ Transplant Limitations

To address the progression of immune-related constraints on organ transplantation, the first part of this thesis contains a historical analysis tracing early transplant motivations and the events that led to the discoveries broadly related to tolerance, rejection, and compatibility. Despite the advancement of those concepts over time, this early history shows that immunosuppression was one of the earliest limiting barriers to successful organ transplantation, and remains one of the most significant technical challenges.

“Transfer of a Human Zygote” (1973), by David De Kretzer, Peter Dennis, Bryan Hudson, John Leeton, Alexander Lopata, Ken Outch, James Talbot, and Carl Wood

On 29 September 1973, researchers David De Kretzer, Peter Dennis, Bryan Hudson, John Leeton, Alexander Lopata, Ken Outch, James Talbot, and Carl Wood published “Transfer of a Human Zygote,” in The Lancet. In the article, the authors describe an experiment that resulted in one of the first pregnancies established via in vitro fertilization, or IVF. Prior to the article’s publication in 1973, there was no published evidence demonstrating whether IVF treatment would work in humans, although evidence existed showing that IVF worked in other mammals for breeding purposes.

Human Papillomavirus (HPV) Strains 6 and 11 and Strains 16 and 18

Human Papillomavirus, or HPV, is a viral pathogen that most commonly spreads through sexual contact. HPV strains 6 and 11 normally cause genital warts, while HPV strains 16 and 18 commonly cause cervical cancer, which causes cancerous cells to spread in the cervix. Physicians can detect those HPV strains, using a Pap smear, which is a diagnostic test that collects cells from the female cervix.

Bailey v. Blue Cross Blue Shield of Virginia (1994)

In 1994, the Eastern Virginia District court case Bailey v. Blue Cross Blue Shield of Virginia established that insurance companies could not deny coverage for experimental stem cell therapy treatments. The plaintiff, Mary Bailey, was diagnosed with advanced stage breast cancer and sought treatment involving high-dose chemotherapy and an advanced stem cell treatment, which was a novelty at the time. Stem cells are cells that have the potential to develop into several different types of cells in the body.

“On the Influence of Abnormal Parturition, Difficult Labors, Premature Birth, and Asphyxia Neonatorum, on the Mental and Physical Condition of the Child, Especially in Relation to Deformities” (1861), by William John Little

In 1861, William John Little published, “On The Influence of Abnormal Parturition, Difficult Labors, Premature Birth, and Asphyxia Neonatorum, on the Mental and Physical Condition of the Child, Especially in Relation to Deformities,” hereafter “Abnormal Parturition,” in the Transactions of the Obstetrical Society of London. In the article, Little discussed the causes and types of what he refers to as abnormal births, and theorized how those births affect an infant’s likelihood of exhibiting a deformity.

Dissertation: A Fetus By Any Other Name: How Words Shaped the Fetal Personhood Movement in US Courts and Society (1884-1973)

The 1973 Supreme Court case Roe v. Wade was a significant event in the story of fetal personhood—the story of whether embryos and fetuses are legal persons. Roe legalized abortion care in the United States (US). However, the story of fetal personhood began long before the 1970s. People have been talking about embryos, fetuses, and their status in science, the law, and society for centuries.

Planned Parenthood v. Danforth (1976)

On 1 July 1976, the US Supreme Court decided in the case Planned Parenthood v. Danforth that provisions of a Missouri law regulating abortion care were unconstitutional. That law, House Bill 1211, restricted abortion care by requiring written consent for each abortion procedure from the pregnant woman as written consent of the woman’s husband if she was married, or the written consent of her parents if she was unmarried and younger than eighteen. House Bill 1211 also required that physicians make efforts to preserve the lives of aborted fetuses.

“What Can We Do About Cancer? The Most Vital and Insistent Question in the Medical World” (1913), by Samuel Hopkins Adams

In 1913, journalist Samuel Hopkins Adams published “What Can We Do About Cancer? The Most Vital and Insistent Question in the Medical World,” hereafter “What Can We Do About Cancer,” in Ladies’ Home Journal. Cancer is a disease that is the result of abnormal cell division in different parts of the body, such as the breasts or the cervix. During that time, many women did not discuss or disclose early symptoms of reproductive cancers, such as breast lumps and abnormal vaginal discharge, out of shame or disgust. Thus, people often considered cancer to be a taboo topic.

“The Prophylactic Forceps Operation” (1920), by Joseph Bolivar DeLee

In 1920, Joseph Bolivar DeLee published the article, “The Prophylactic Forceps Operation,” in which he describes how physicians can manually remove a neonate from a laboring woman’s vagina with the use of sedating drugs and forceps. The procedure, according to DeLee, resulted in decreased rates of complications and mortality for both the woman and neonate. DeLee claimed the procedure could reduce damage to the woman such as prolapse, or when internal pelvic organs push down and sometimes protrude from the vagina, and fatal infant brain bleeding.

Virginia Apgar (1909–1974)

During the mid-twentieth century, Virginia Apgar worked as an obstetrical anesthesiologist and gave drugs to women that reduced their pain during childbirth in the US. In 1953, Apgar created a scoring system, called the Apgar score, that uses five measurements, including heart rate and breathing rate. The Apgar score evaluates newborn infants and determines who needs immediate medical attention. Apgar's work helped decrease infant mortality rates. As of 2020, hospitals around the world use the Apgar score.

Test-Tube Baby

A test-tube baby is the product of a successful human reproduction that results from methods beyond sexual intercourse between a man and a woman and instead utilizes medical intervention that manipulates both the egg and sperm cells for successful fertilization. The term was originally used to refer to the babies born from the earliest applications of artificial insemination and has now been expanded to refer to children born through the use of in vitro fertilization, the practice of fertilizing an embryo outside of a woman's body.

Test-Tube Baby

“Test-tube baby” is a term used to refer to a baby produced through artificial insemination or in vitro fertilization, also called IVF. During artificial insemination, a physician injects carefully selected sperm into a women’s uterus to fertilize her eggs. During IVF, a trained professional harvests eggs from a female donor. Those eggs are fertilized with carefully selected sperm in a petri dish.

Rh Incompatibility in Pregnancy

Rh incompatibility occurs when a pregnant woman whose blood type is Rh-negative is exposed to Rh-positive blood from her fetus, leading to the mother s development of Rh antibodies. These antibodies have the potential to cross the placenta and attach to fetal red blood cells, resulting in hemolysis, or destruction of the fetus 's red blood cells. This causes the fetus to become anemic, which can lead to hemolytic disease of the newborn. In severe cases, an intrauterine blood transfusion for the fetus may be required to correct the anemia.

Rh Incompatibility in Pregnancy

Rh factor is a protein found on the outside of Rh-positive red blood cells. Rh incompatibility during pregnancy occurs when an Rh-negative mother is pregnant with an Rh-positive fetus. During delivery, the fetus' Rh-positive blood is introduced into the mother’s body. The Rh-negative mother’s body begins to produce antibodies that attack and kill Rh-positive blood cells. Since the crossover of blood normally occurs during delivery, an Rh-negative woman’s first pregnancy is normally not affected.

Thesis: Overcoming a Cycle of Shame Through Menstrual Education: How Sources of Information Prepare Girls to Detect and Treat Abnormal Menstrual Bleeding

Developing a codebook of definitions and exemplars of significant text segments and applying it to the collected data revealed several themes. For example, mothers, friends, teachers, the Internet, and social media are among the most common sources of information about menstrual hygiene and health. Yet, women reported that those sources of information
often echoed stigmatized ideas about menstruation, eliciting feelings of shame and fear.
That poor quality of information was instrumental to women’s abilities to detect and
report abnormal menstrual bleeding.
