Book Description
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.

Book Description
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.

Book Description
Puberty is a critical period of development characterized by rapid physiological changes and significant brain reorganizing and remodeling in women. These rapid changes render the developing brain particularly vulnerable to stress and exogenous factors. According to recent trends, women are increasingly likely to begin using exogenous/synthetic hormones (i.e., oral contraceptives; OCs) as early as during puberty. While millions of women worldwide use OCs, the extent of OC-related structural, functional, and behavioral changes and the role of ovarian steroid hormones remain elusive. Thus, we hypothesized that hormonal modulation through OC use during puberty would result in unique neural and behavioural outcomes compared to OC use later in life. The current thesis examined the effects of OC use, especially during puberty, on cortisol reactivity, brain structure, and brain function during a working memory cognitive task (Article 1). Next, we examined whether the task-related functional differences between OC users and non-OC users could be informed by resting state functional connectivity in the default mode, salience, central executive, and, reward networks (Article 2). Lastly, we examined the roles of progesterone and estradiol on emotion processing during the cognitive task in all women (Article 3). The current dissertation has addressed OC-related differences to the brain and behaviour and the influence of ovarian steroid hormones in these differences. These studies have demonstrated that OC use is related to specific structural and functional differences, with some findings being dependent on the age of OC onset and duration of OC use. The findings offer critical insight into women's brain health and bring awareness to the potential behavioural and neural consequences of OC use and role of ovarian steroid hormones.

Book Description
Please note: This is a companion version & not the original book. Sample Book Insights: #1 We can learn a lot about women by understanding the things that our brains were designed to do. Each one of us is the result of an unbroken chain of successful survival and reproduction that has gone on now for millions of years. #2 The size of a woman’s gametes determines whether she is female. Women have larger, more expensive gametes than men, which means that women are prepared to invest more in any children they may have. #3 The fact that men’s and women’s bodies are the limiting factors in terms of their ability to reproduce means that women can’t increase access to gene-transmission opportunities simply by finding new partners. #4 Women are typically less sexually opportunistic than men. This is because being sexually opportunistic has historically been very costly for women, while it has come with the possibility of transmitting genes into the next generation without too many costs.

Book Description
The "contraceptive revolution" of the 1960s and 1970s introduced totally new contraceptive options and launched an era of research and product development. Yet by the late 1980s, conditions had changed and improvements in contraceptive products, while very important in relation to improved oral contraceptives, IUDs, implants, and injectables, had become primarily incremental. Is it time for a second contraceptive revolution and how might it happen? Contraceptive Research and Development explores the frontiers of science where the contraceptives of the future are likely to be found and lays out criteria for deciding where to make the next R&D investments. The book comprehensively examines today's contraceptive needs, identifies "niches" in those needs that seem most readily translatable into market terms, and scrutinizes issues that shape the market: method side effects and contraceptive failure, the challenge of HIV/AIDS and other sexually transmitted diseases, and the implications of the "women's agenda." Contraceptive Research and Development analyzes the response of the pharmaceutical industry to current dynamics in regulation, liability, public opinion, and the economics of the health sector and offers an integrated set of recommendations for public- and private-sector action to meet a whole new generation of demand.
