Seeing that the average brain-weight of women is about five ounces less than that of men, on merely anatomical grounds we should be prepared to expect a marked inferiority of intellectual power in the former.

But as soon as the brain, and with it the organism as a whole, reaches the stage of full development, it becames apparent that there is a greater power of amassing knowledge on the part of the male

Whether we look to the general average or to the intellectual giants of both sexes, we are similarly met with the general fact that a woman's information is less wide, and deep, and thorough, than that of a man.

There is an undeniable history of biological data being used in attempts to justify sexist views [13,14,15], and while reporting neuroanatomical sex differences is not an inherently sexist act, modern research on this topic is not isolated from its history.

Rather than avoiding, dismissing, or over-interpreting findings of brain sex differences, more accurate description could reduce the misrepresentation and misuse of such research, both within the scientific community and throughout society as a whole.

Although most individuals can be categorized as female or male based on this system (a designation which is typically made based on genital phenotype at birth), sex is not strictly binary. In fact, intersex individuals, who represent ~ 1% of the population, exhibit an abundance of variation across sex chromosome combinations, sex hormone concentrations, and bodily phenotypes.

It affects your family, your finances, your health, and how you will spend your time for the rest of your life.

Our society treats having children as a default, and people who don't want kids are often vilified, pressured, and made into outcasts.

However, it should be remembered that having children is a choice, and there are many people who are childfree by choice, not only by circumstance.

Childless women may be at a greater risk of experiencing poor physical and mental health when compared to the Australian population.

Women without children have also been found to have an increased risk of breast cancer

Record linkage data from England and Wales suggests that women less than 60 years of age without children have significantly higher mortality rates compared with women with two children

We place particular emphasis on social contexts and how the impact of parenthood on well-being depends on marital status, gender, race/ethnicity, and socioeconomic status.

However, the point of critical inquiry is not to deny differences between the sexes, but to ensure a full understanding of the findings and meaning of any particular research report.

Behavioral differences may stem from complementary roles in procreation and social structure; examples include enhanced motor and spatial skills and greater proclivity for physical aggression in males and enhanced verbally mediated memory and social cognition in females

owever, the way much research on sexual differentiation is conducted and communicated has come under intense criticism from scholars in both the natural and social sciences.
