Sex ratio and women's career choice: does a scarcity of men lead women to choose briefcase over baby?
Although the ratio of males to females in a population is known to influence behavior in nonhuman animals, little is known about how sex ratio influences human behavior. We propose that sex ratio affects women's family planning and career choices. Using both historical data and experiments, we examined how sex ratio influences women's career aspirations. Findings showed that a scarcity of men led women to seek high paying careers and to delay starting a family. This effect was driven by how sex ratio altered the mating market, not just the job market. Sex ratios involving a scarcity of men led women to seek lucrative careers because of the difficulty women have in finding an investing, long term mate under such circumstances. Accordingly, this low male sex ratio produced the strongest desire for lucrative careers in women who are least able to secure a mate. These findings demonstrate that sex ratio has far reaching effects in humans, including whether women choose briefcase over baby.

The Shettles Method of Sex Selection
In the 1960s in the United States Landrum B. Shettles developed the Shettles method, which is a procedure for couples to use prior to and during an intercourse to increase their chances of conceiving a fetus [7] of their desired sex. Shettles, a physician, who specialized in obstetrics and gynecology, found a difference in the size and shape of male sperm [8] cells that he correlated with the different sex chromosomes they carry. Based on that finding, Shettles developed procedures for couples to follow based on whether they desire a female or a male fetus [7] and published them in the 1970 book, Your Baby's Sex: Now You Can Choose. The Shettles method is based on the idea that male producing sperm [8] prefer alkaline conditions, whereas femaleproducing sperm [8] prefer acidic conditions. The method provides couples with a procedure intended to enhance the favored environment for the sperm [8] that will supposedly produce the desired sex, including female douches to be used before intercourse and how to time sexual intercourse [9] within the female menstrual cycle. The book Your Baby's Sex: Now You Can Choose, made the Shettles method a widely popular method of natural sex selection.

Reproductive Autonomy and Social Sex Selection: A Chance of a Choice?
Through preimplantation genetic diagnosis (PGD) individuals can now reliably choose the sex of their baby. However, PGD is largely prohibited for individuals seeking to sex select for non medical reasons. This article argues that to protect reproductive autonomy, individuals should be allowed to make reproductive choices, regardless of their motivations, unless those choices would cause serious harms to others. It follows that social sex selection should not be prohibited on the basis of moral objections, only when it will cause serious harm. This article considers the opposing ethical framework of parental virtues. A reproductive autonomy framework is preferred, given the challenges of determining and applying parental virtues to social sex selection. This article examines three potential harms identified by opponents to sex selection, and argues that while these remain speculative they do not justify the curtailing of reproductive autonomy.

Attitudes about Sex Selection and Sex Preference in Iranian Couples Referred for Sex Selection Technology
Background Gender preference is prevalent in some communities and using medical techniques to choose the baby's sex may cause the gender discrimination and gender imbalance in communities. Therefore, evaluating the gender preferences and attitudes towards using sex selection technologies seems to be necessary. Methods This cross sectional study was conducted in Avicenna Fertility Center. Participants were 100 women with one child who were referred for sex selection. Data were collected through self developed questionnaires. The questions were designed by the researchers at the experts' panel. To determine the validity of the questionnaire, the viewpoints of professors specialized in these issues were obtained. The statistical analysis of the data was performed using SPSS software (Version 11.5) and p 0.05 was considered significant. Results Tendency toward the male was more than female sex (55.5% male, 15.5% female and 28.5% no tendency) Majority of participants agreed with sex selection with medical reason and sex selection in order to balance the family. Women's level of education had positive effect on agreements to fetal sex selection with medical and non medical reasons (p 0.001) Conclusion Although gender preferences were toward the male sex but this preference was not very strong. Most participants agreed with non medical sex selection for balancing the sex composition of their children. It doesn't seem that non medical sex selection for family balancing causes severe sex imbalance in Iran.

Pretty in pink: The early development of gender stereotyped colour preferences.
Parents commonly dress their baby girls in pink and their baby boys in blue. Although there is research showing that children prefer the colour blue to other colours (regardless of gender) there is no evidence that girls actually have a special preference for the colour pink. This is the focus of the current investigation. In a large cross sectional study, children aged 7 months to 5 years were offered eight pairs of objects and asked to choose one. In every pair, one of the objects was always pink. By the age of 2, girls chose pink objects more often than boys did, and by the age of 2.5, they had a significant preference for the colour pink over other colours. At the same time, boys showed an increasing avoidance of pink. These results thus reveal that sex differences in young children's preference for the colour pink involves both an increasing attraction to pink by young girls and a growing avoidance of pink by boys.

Female and male responses to cuteness, age and emotion in infant faces
Neonatal features in the newborn are thought to trigger parental care, the most fundamental prosocial behaviour. The underlying mechanisms that release parental care have not yet been resolved. Here we report sex differences in the ability to discriminate cues to cuteness despite equivalence in the capability to discriminate age and facial expression. These differences become apparent in a task where adults were asked to choose the cuter of two babies. While women could reliably choose the cuter infant, men had more difficulty in doing so. When showing the exact same face pairs but asking to choose the younger or the happier baby, there was no sex difference. These results suggest that the sex difference in the ability to discriminate cues to cuteness in infants underlies female specific emotive responses. We argue that this reactivity expressed by women evolved to ensure that a female allocates her caretaking resources to her youngest offspring while it needs mothering care.
