Considered the definitive statement on modern birth-control technologies, this Anniversary Edition includes new, up-to-date chapters on the dangers of Norplant and the risks women on the Pill face today. Because it tells the truth about the Pill, this book provides women with the information they need to make good choices for their own body.

An eye-opening book that reveals crucial information every woman taking hormonal birth control should know This groundbreaking book sheds light on how hormonal birth control affects women--and the world around them--in ways we are just now beginning to understand. By allowing women to control their fertility, the birth control pill has revolutionized women's lives. Women are going to college, graduating, and entering the workforce in greater numbers than ever before, and there's good reason to believe that the birth control pill has a lot to do with this. But there's a lot more to the pill than meets the eye. Although women go on the pill for a small handful of targeted effects (pregnancy prevention and clearer skin, yay!), sex hormones can't work that way. Sex hormones impact the activities of billions of cells in the body at once, many of which are in the brain. There, they play a role in influencing attraction, sexual motivation, stress, hunger, eating patterns, emotion regulation, friendships, aggression, mood, learning, and more. This means that being on the birth control pill makes women a different version of themselves than when they are off of it. And this is a big deal. For instance, women on the pill have a dampened cortisol spike in response to stress. While this might sound great (no stress!), it can have negative implications for learning, memory, and mood. Additionally, because the pill influences who women are attracted to, being on the pill may inadvertently influence who women choose as partners, which can have important implications for their relationships once they go off it. Sometimes these changes are for the better . . . but other times, they're for the worse. By changing what women's brains do, the pill also has the ability to have cascading effects on everything and everyone that a woman encounters. This means that the reach of the pill extends far beyond women's own bodies, having a major impact on society and the world. This paradigm-shattering book provides an even-handed, science-based understanding of who women are, both on and off the pill. It will change the way that women think about their hormones and how they view themselves. It also serves as a rallying cry for women to demand more information from science about how their bodies and brains work and to advocate for better research. This book will help women make more informed decisions about their health, whether they're on the pill or off of it.

A Chicago Tribune "Best Books of 2014" • A Slate "Best Books 2014: Staff Picks" • A St. Louis Post-Dispatch "Best Books of 2014" The fascinating story of one of the most important scientific discoveries of the twentieth century. We know it simply as "the pill," yet its genesis was anything but simple. Jonathan Eig's masterful narrative revolves around four principal characters: the fiery feminist Margaret Sanger, who was a champion of birth control in her campaign for the rights of women but neglected her own children in pursuit of free love; the beautiful Katharine McCormick, who owed her fortune to her wealthy husband, the son of the founder of International Harvester and a schizophrenic; the visionary scientist Gregory Pincus, who was dismissed by Harvard in the 1930s as a result of his experimentation with in vitro fertilization but who, after he was approached by Sanger and McCormick, grew obsessed with the idea of inventing a drug that could stop ovulation; and the telegenic John Rock, a Catholic doctor from Boston who battled his own church to become an enormously effective advocate in the effort to win public approval for the drug that would be marketed by Searle as Enovid. Spanning the years from Sanger’s heady Greenwich Village days in the early twentieth century to trial tests in Puerto Rico in the 1950s to the cusp of the sexual revolution in the 1960s, this is a grand story of radical feminist politics, scientific ingenuity, establishment opposition, and, ultimately, a sea change in social attitudes. Brilliantly researched and briskly written, The Birth of the Pill is gripping social, cultural, and scientific history.

Discusses the pros and cons of taking birth control pills, their effects on the human body, health risks and more.

Unearthing individual stories and statistical records from previously overlooked birth control clinics, Cathy Moran Hajo looks past the rhetoric of the birth control movement to show the relationships, politics, and issues that defined the movement in neighborhoods and cities across the United States. Whereas previous histories have emphasized national trends and glossed over the majority of clinics, Birth Control on Main Street contextualizes individual case studies to add powerful new layers to the existing narratives on abortion, racism, eugenics, and sterilization. Hajo draws on an original database of more than 600 clinics run by birth control leagues, hospitals, settlement houses, and public health groups to isolate the birth control clinic from the larger narrative of the moment. By revealing how clinics tested, treated, and educated women regarding contraceptives, she shows how clinic operation differed according to the needs and concerns of the districts it served. Moving thematically through the politicized issues of the birth control movement, Hajo infuses her analysis of the practical and medical issues of the clinics with unique stories of activists who negotiated with community groups to obey local laws and navigated the swirling debates about how birth control centers should be controlled, who should receive care, and how patients should be treated.

This data booklet highlights estimates of the prevalence of individual contraceptive methods based on the World Contraceptive Use 2019 (which draws from 1,247 surveys for 195 countries or areas of the world) and additional tabulations obtained from microdata sets and survey reports. The estimates are presented for female and male sterilisation, intrauterine device (IUD), implant, injectable, pill, male condom, withdrawal, rhythm and other methods combined.

Evaluates evidence for an increased risk of cancer in women using combined oral contraceptives, progestogen-only hormonal contraceptives, post-menopausal estrogen therapy, and post-menopausal estrogen-progestogen therapy. Although the carcinogenicity of these preparations has been extensively investigated, the book stresses the many complex methodological issues that must be considered when interpreting findings and weighing results. Evidence of an association between use of these preparations and positive effects on health, including a reduced risk of some cancers, is also critically assessed. The first and most extensive monograph evaluates evidence of an association between the use of combined oral contraceptives and cancer at nine sites. Concerning breast cancer, the evaluation concludes that, even if the association is causal, the excess risk for breast cancer associated with patterns of use that are typical today is very small. Studies of predominantly high-dose preparations found an increased risk of hepatocellular carcinoma in the absence of hepatitis viruses. Citing these findings, the evaluation concludes that there is sufficient evidence in humans for the carcinogenicity of combined oral contraceptives. The evaluation also found sufficient evidence for the carcinogenicity of some, but not all, combined preparations in animals. Combined oral contraceptives were classified as carcinogenic to humans. The evaluation also cites conclusive evidence that these agents have a protective effect against cancers of the ovary and endometrium. Progestogen-only contraceptives are evaluated in the second monograph, which considers the association with cancer at six sites. The evaluation found no evidence of an increased risk for breast cancer. Although the evaluation found sufficient evidence in animals for the carcinogenicity of medroxyprogesterone acetate, evidence for the carcinogenicity of progestogen-only contraceptives in humans was judged inadequate. Progestogen-only contraceptives were classified as possibly carcinogenic to humans. The third monograph, on post-menopausal estrogen therapy, considers evidence of an association with cancer at eight sites. Findings from a large number of epidemiological studies indicate a small increase in the risk of breast cancer in women who have used these preparations for five years or more. Studies consistently show an association between use of post-menopausal estrogen therapy and an increased risk for endometrial cancer. Data on the association with other cancers were either inconclusive or suggested no effect on risk. The evaluation concludes that post-menopausal estrogen therapy is carcinogenic to humans. The final monograph evaluates the association between the use of post-menopausal estrogen-progestogen therapy and cancer at four sites. The evaluation of limited data on breast cancer found an increased relative risk observed with long-term use. Data were judged insufficient to assess the effects of past use and of different progestogen compounds, doses, and treatment schedules. For endometrial cancer, the evaluation found an increase in risk relative to non-users when the progestogen was added to the cycle for 10 days or fewer. Post-menopausal estrogen-progestogen therapy was classified as possibly carcinogenic to humans. Concerning post-menopausal therapy in general, the book notes that evidence of carcinogenic risks must be placed in perspective of potential benefits. The prevention of osteoporotic fractures is cited as the best-established benefit. Evidence also suggests that estrogen prevents heart disease and may prevent memory loss and dementia.
