The Weaker Sex

The Weaker Sex - New York Times: "This Father's Day, we need to rededicate ourselves to deepening our knowledge of male physiology.

Men's troubles begin during the earliest days in the womb. Even though there are more male than female embryos, there are more miscarriages of male fetuses. Industrial countries are also witnessing a decline in male to female birth ratios, and we don't know why.

Some scientists have argued that the probability of a male child declines as parents (especially fathers) age. Still others have cited the prevalence of pesticides, which produce more birth defects in male children.

Even when a boy manages to be born, he's still behind the survival eight ball: he is three to four times more likely than girls to have developmental disorders like autism and dyslexia; girls learn language earlier, develop richer vocabularies and even hear better than boys. Girls demonstrate insight and judgment earlier in adolescence than boys, who are more impulsive and take more risks than their sisters. Teenage boys are more likely to commit suicide than girls and are more likely to die violent deaths before adulthood.

As adults, too, men die earlier than women. Twice as many men as women die of coronary artery disease, which manifests itself a decade earlier in men than women; when it comes to cancer, the news for men is almost as bad. Women also have more vigorous immune systems than men: of the 10 most common infections, men are more likely to have serious encounters with seven of them.

While depression is said to be twice as frequent in women as in men, I'm convinced that the diagnosis is just made more frequently in women, who show a greater willingness to discuss their symptoms and to ask for help when in distress."
