Here's the conclusion of "Love, Sex and the Male Brain":
His emotions run deep
Although men have earned the reputation for being more stoic than women, they actually have stronger emotional reactions than we do. They just don't show it very often. Studies of men's faces show that the male brain's initial emotional reaction can be stronger than the female brain's. But within 2.5 seconds, he changes his face to hide the emotion, or even reverse it. The repeated practice of hiding his emotions gives men the classic poker face. It's his poker face and his analytical response to personal problems that can put him in the doghouse. She's crying as she talks about what's wrong with the relationship, and instead of hugging her, his mind is racing to find a way to resolve the problem as soon as possible. With practice and because of the way their brains are wired, men use their analytical brain structures, not their emotional ones, to find a solution. They enjoy this advantage, but women often take affront to it. When you're telling your husband your problem and he tries to solve it instead of hearing you out, you may think he's being insensitive. But that's not what's going on in his brain. He's working to solve the problem so he can relieve your pain as quickly as possible. Not because he doesn't care or doesn't want to listen, but because he loves you.
'Lovable Grandpas' and 'Grumpy Old Men'
As men age, the male brain hormones change and the male brain and body goes into the stage of life called andropause. The king of male hormones -- testosterone -- goes down and the queen of female hormones -- estrogen -- goes up. Whether Grandpa is your kids' hero or the grouch they hate to visit depends a lot on how he handles these hormonal changes. For example, if his testosterone levels drop to an abnormally low level, he can feel tired, irritable and even depressed. Some men in this condition seek hormone replacement therapy and others find relief in exercise, more frequent sex, and spending more time with other people. The grandpa that kids can't wait to see is the one who's feeling the effects of the hormone oxytocin, often called the "cuddle hormone." He's fun and playful and likes to hear what his grandchildren have to say. He's much more patient with your children than he was with you, when you were growing up. The love circuits of the mature male brain can be hijacked by his grandkids, even more than they were by his own children.
The 'Lonely Hearts Club'
Not only is the mature male brain more receptive to closer bonds, but it's also more sensitive to loneliness. Nobody thrives when they're lonely, but it seems to take a major toll on older men. Sixty percent of divorces in couples over the age of 50 are initiated by women, leaving their husbands shell-shocked and devastated. Once his wife leaves, unless he makes a point of socializing more with other people, his brain stops getting the social workout it needs to make him feel good about himself. If he becomes a loner, his social-approval circuits don't get activated. In brain scan studies of older males researchers have found that the brain's pleasure and reward areas, the VTA and the NAc, remain more active in men who are social. So don't begrudge the divorcee or the new widower some socializing and seeking female companionship.
The bottom line
The human brain is the best learning machine on the planet and human beings are capable of making major changes in our lives. But there are some things that the male brain and female brain are not likely to change anytime soon. And it makes more sense to deal with these brain realities, than to argue with them or ignoring them.
The best advice I have for women is make peace with the male brain. Let men be men.
