Book excerpt: There is extensive evidence that vertebrates of all classes have the ability to control the sexes of the offspring they produce. Despite dramatic differences in the mechanisms by which different taxa determine the initial sex of offspring, each group has found its own way of adjusting offspring sex ratios in response to social and environmental cues. For example, stress is a well-known modulator of offspring sex in members of all groups studied to date. Food availability, and limitation in particular, is another common cue that stimulates biases in offspring sex ratios in a wide variety of species. Offspring sex can be adjusted at the primary level, which occurs prior to conception, or at the secondary level, during embryonic development. While the mechanistic pathways that ultimately result in sex ratio biases and the developmental time-points sensitive to those mechanisms likely differ among taxa, the key involvement of steroid hormones in the process of sex ratio adjustment appears to be pervasive throughout. This book reviews the systems of sex determination at play in different vertebrate groups, summarizes the evidence that members of all vertebrate taxa can facultatively adjust offspring sex, and discusses when and how these adjustments can take place.

Available in PDF, EPUB and Kindle. Book excerpt: Choosing Unsafe Sex focuses on the ways in which condom refusal and beliefs regarding HIV testing reflect women's hopes for their relationships and their desires to preserve status and self-esteem. Many of the inner-city women who participated in Dr. Sobo's research were seriously involved with one man, and they had heavy emotional and social investments in believing or maintaining that their partners were faithful to them. Uninvolved women had similarly heavy investments in their abilities to identify or choose potential partners who were HIV-negative. Women did not see themselves as being at risk for HIV infection, and so they saw no need for condoms. But they did recommend that other women, whom they saw as quite likely to be involved with sexually unfaithful men, use them.

Available in PDF, EPUB and Kindle. Book excerpt: For the past fifteen years I have run into many couples, friends of the author - some of whom specifically wanted a girl, and a few others who specifically wanted a boy most of whom are now close friends of mine. Each and every one of them under the guidance of Dr. Paul Gouda, has succeeded in securing the desired gender of their baby. Last year, in a casual conversation, I mentioned that I wanted to breed my expensive German Sheppard, an elite line of breeding from which the local police has a duty dog. I commented that several friends wanted a pup, and they all wanted a male. I asked my friend Paul, the author, for his advice. He put the male and the female on a special supplementary diet he provided, and he performed the artificial insemination after performing a specific semen treatment. Two months later, a litter of 11 pups, 11 males. In fact, for the past 8 years it never ceased to amaze me how Dr. Gouda, who is a Great Dane lover, has bred his Danes with a bold online announcement months prior to the whelping of the puppies that they all will be males or they all will be females! And yes, he was never wrong. And, two years ago, coaching a Chinese couple, mutual friends, Dr. Gouda published a congratulatory ad in the local metropolitan newspaper congratulating them in advance on their yet-to-be conceived son. 11 months later, they named him Paul. This book is an invaluable tool for every couple. Dr. Timothy Bucha, Ph.D. Dr. Paul H. Ramses Gouda is a renowned research scientist and an analytical chemist. After first attending the medical school, he decided to specialized in chemical pharmaceutical research. He is the scientist behind the invention of three new, patent-pending, pharmaceutical drugs designed around the concept of chemical manipulation of hormonal compounds. His personal experience in mammal sex selection, both human conception and animal breeding, has an unquestionable record of 100% success rate. This book is one of a kind. A must for every library. Dr. R. R. Redmond, MD.

Available in PDF, EPUB and Kindle. Book excerpt: Finalist for the Pulitzer Prize A Slate Best Book of 2011 A Discover Magazine Best Book of 2011 Lianyungang, a booming port city, has China's most extreme gender ratio for children under four: 163 boys for every 100 girls. These numbers don't seem terribly grim, but in ten years, the skewed sex ratio will pose a colossal challenge. By the time those children reach adulthood, their generation will have twenty-four million more men than women. The prognosis for China's neighbors is no less bleak: Asia now has 163 million females "missing" from its population. Gender imbalance reaches far beyond Asia, affecting Georgia, Eastern Europe, and cities in the U.S. where there are significant immigrant populations. The world, therefore, is becoming increasingly male, and this mismatch is likely to create profound social upheaval. Historically, eras in which there have been an excess of men have produced periods of violent conflict and instability. Mara Hvistendahl has written a stunning, impeccably-researched book that does not flinch from examining not only the consequences of the misbegotten policies of sex selection but Western complicity with them.

Available in PDF, EPUB and Kindle. Book excerpt: Autonomy is fundamental to liberalism. But autonomous individuals often choose to do things that harm themselves or undermine their equality. In particular, women often choose to participate in practices of sexual inequality&—cosmetic surgery, gendered patterns of work and childcare, makeup, restrictive clothing, or the sexual subordination required by membership in certain religious groups. In this book, Clare Chambers argues that this predicament poses a fundamental challenge to many existing liberal and multicultural theories that dominate contemporary political philosophy. Chambers argues that a theory of justice cannot ignore the influence of culture and the role it plays in shaping choices. If cultures shape choices, it is problematic to use those choices as the measure of the justice of the culture. Drawing upon feminist critiques of gender inequality and poststructuralist theories of social construction, she argues that we should accept some of the multicultural claims about the importance of culture in shaping our actions and identities, but that we should reach the opposite normative conclusion to that of multiculturalists and many liberals. Rather than using the idea of social construction to justify cultural respect or protection, we should use it to ground a critical stance toward cultural norms. The book presents radical proposals for state action to promote sexual and cultural justice.
