"Until recently, there have been two groups of people: those who argue sex differences are innate and should be embraced and those who insist that they are learned and should be eliminated by changing the environment. Sax is one of the few in the middle -- convinced that boys and girls are innately different and that we must change the environment so differences don't become limitations."

Praise for Why Gender Matters:
". . . a lucid guide to male and female brain differences. . ."
The New York Times
"When I was a college freshman, a male teaching assistant I sought help from told me matter-of-factly
that women were not good at inorganic chemistry. Had I been armed with Why Gender Matters,
about how biological differences between the sexes can influence learning and behavior,
I could have managed an informed rejoinder to go along with my shocked expression. . . .
Using studies as well as anecdotes from his practice and visits to classrooms,
[Sax] offers advice on such topics as preventing drug abuse and motivating students. . . .
The book is thought-provoking, and Sax explains well the science behind his assertions. . .
[Why Gender Matters] is a worthy read for those who care about how best to prepare children
for the challenges they face on the path to adulthood."
Scientific American Mind
"Convincing. . . Psychologist and family physician Leonard Sax, using 20 years of published research,
offers a guide to the growing mountain of evidence that girls and boys really are different. . .
This extremely readable book also includes shrewd advice on discipline,
and on helping youngsters avoid drugs and early sexual activity.
Sax's findings, insights and provocative point-of-view should be of interest and help to many parents."
-New York Post
“Why Gender Matters is a fabulous resource for teachers and parents.
Dr. Sax combines his extensive knowledge of the research on gender issues with practical advice in cogent,
highly readable prose. I am eager to have my colleagues at school read this book and discuss it!”
—Martha Cutts, Head of School, Agnes Irwin School, Rosemont, Pennsylvania
"As the principal of an elementary school, I am constantly on the lookout for outstanding articles
and books about gender-specific learning differences.
Why Gender Matters is the best I've read."
-John Webster, Head of School, the San Antonio Academy
"Why Gender Matters is an outstanding work of scholarship. I am going to make it our 'faculty read' this summer."
-Paul Krieger, Headmaster, Christ School (North Carolina)
“In this reader-friendly book, Dr. Sax combines his comprehensive knowledge of the scientific literature
with numerous interesting case studies to argue for his thesis that single-sex education is advantageous.”
— Dr. Sandra Witelson, Albert Einstein/Irving Zucker Chair in Neuroscience, McMaster University
“Extremely interesting . . . Challenged many of my basic assumptions and helped me to think about gender in a new way.”
—Joan Ogilvy Holden, Head of School, St. Stephen’s School, Alexandria, Virginia
"I simply will never be able to express how eye-opening this book has been for me.
Yes me -- even though I thought I was a boy-raising specialist. After all, I have produced four healthy and smart athletes. I must know what I'm doing. But many of my boy-raising days I thought I was going mad. I'd come home from some sports event trembling because of the way the coach yelled at my kid. I'd ask my husband and whichever son it happened to be that day how they could stand being yelled at like that. Almost every time husband and son would look at me and not have any recollection of being yelled at during the game. Now I understand!!!!!!!!!"
-Janet Phillips, mother of four boys, Seneca, Maryland
"Why Gender Matters is an instructive handbook for parents and teachers . . .
to create ways to cope with the differences between boys and girls."
-The Boston Globe
"Outstanding book, required reading for any parent."
Timothy Lundeen, father, San Francisco, California
"Fascinating . . . This book is interesting because it takes an 'outside the box' position on gender. Paradoxically, Sax says, gender-neutral education favors the learning style of one sex or the other, and so only drives men and women into the usual stereotyped fields. The best way to raise your son to be a man who is caring and nurturing, says Sax, is to first of all let him be a boy. The best way to produce a female mathematician is to first of all let her be a girl. . . I think Sax is on to something. Mature men and women do draw on qualities that stereotypically belong to the opposite sex. But the easiest way to get them to that point is to first make them confident about being a man or a woman. . . Sax adds that children are less happy and confident nowadays because no one is teaching them how to be men and women. This is a powerful, even obvious insight, once you dare think it. . . In quick succession, with Mary Eberstadt's Home Alone America and Leonard Sax's Why Gender Matters, we've seen two important, creative, and politically incorrect takes on family life and childhood."
-Stanley Kurtz, National Review Online.
Dr. Sax's education and experience

After graduating Phi Beta Kappa from the Massachusetts Institute of Technology (MIT) in 1980 with a bachelor's degree in biology, Dr. Sax began the combined M.D.-Ph.D. program at the University of Pennsylvania. He graduated from Penn in 1986 with a Ph.D. in psychology and the M.D. degree. He went on to do a 3-year residency in family practice at Lancaster General Hospital in Lancaster, Pennsylvania. Since completing that residency in 1989, he has been
in clinical practice as a family physician. In 1990, he
launched private medical practice in suburban Montgomery County, Maryland, about 30 minutes northwest of the District of Columbia. He practiced in the same location,
serving families in the same small town, for 18 years (1990 - 2008). In May 2008, Dr. Sax retired from medical practice in order to devote himself full-time to his work as a writer, a father, and an activist for gender equity (this last category includes
his work leading NASSPE).

What's happening to boys?
Washington Post, March 31, 2006.
In his op-ed for the Washington Post March 31 2006, Dr. Sax called attention to the growing phenomenon of the
"Failure to Launch" boy/man: a young man in his 20's, or even his 30's, who is still living at home with his parents --
and who doesn't see what the problem is. The Washington Post invited Dr. Sax to host a one-hour
on-line chat, which broke all previous records for the Washington Post: they shut the
system down after receiving 395 posts. You can read
