Is Your Testosterone Level Low?

A couple of months ago I discussed how to boost your testosterone; now let’s focus on the myriad of causes and symptoms of low testosterone or hypogonadism. Male hypogonadism can be congenital or can develop later in life.  Your symptoms and treatment options will depend on at what point your hypogonadism occurs.  For example, hypogonadism […]

It Takes Balls to Be a Dad (Actually, Smaller Ones)

Father with smaller testicles are generally more involved than their bigger-balled brother in caring for their children and respond more when looking at pictures of those children. At least that’s what researchers at Emory University in Atlanta discovered.

The research project with the brainchild of James Rolling, an anthropologist who was trying to figure out what makes some dads more involved than others. So he and his team did MRIs of the brain and balls of 70 men, all of whom had children 1-2 years old. They compared their results with surveys—filled out by the dads and the moms—about the dad’s level of involvement. And they also measured the men’s testosterone levels, finding that dads who provided more childcare tended to have lower levels.

Testicle size and sperm count are closely linked: the bigger the balls, the more sperm there is. So this team of anthropologist speculated that having more sperm would make a man want to spread it around as far and wide as he could. That would leave less time for—and interest in—child care.

The connection between the round parts of a man’s package and his level of involvement with his kids is pretty well-known—at least among other primates. Research has found that male chimps, which don’t do much to care for their offspring, have testes that are twice as large as a human male’s. But gorillas, which are very protective of their babies, have smaller balls.

Biology Keeps Men from Having Sex with Best Friends’ Wives

In movies, books, and sometimes even real life, you often hear stories of men sleeping with their best friends’ wives. But in reality, that happens a lot less that you’d think. In fact, men may actually be biologically to stay away from the fruit of the forbidden tree (isn’t that poetic?). Researchers at the University […]

Testosterone Is Bad. No, It’s Good. No, Bad. Wait, It’s Good Again

The news about testosterone changes so quickly that just reading about it could give you whiplash. On one hand, testosterone increases sex drive and muscle growth. That’s good. On the other hand, it’s associated with hair loss and increased risk of prostate cancer. That’s bad. Now new research is looking at testosterone as a way […]

Mother Nature Never Had to Balance Work and Family

Dear Mr. Dad: My daughter is five days old and today I had to go back to work. All day, I’ve felt an impending sadness that only gets worse. All I want is to be home with my family. I have to go to work and be responsible, but I can’t shake this horrible sadness.

A: Up to 85 percent of new moms go through what’s called the “baby blues”—feelings of sadness and depression that last for a few days or weeks and then slowly fade. It sounds like you’re going through something very similar. Plus, you’ve slammed right into one of the biggest challenges today’s fathers face: how to effectively balance their work and family lives.

Birth control for men? We’re getting closer…

Until now, men who are concerned with unwanted pregnancy (and that, contrary to stereotype, would be just about all men) have had two basic options: vasectomy and condoms. But that may be changing soon.

Researchers are now investigating a gel that, when applied to a man’s skin, drastically lowers his sperm count. That also lowers the risk for pregnancy (but, unfortunately, doesn’t eliminate it completely).

Christina Wang, a professor at the Los Angeles Biomedical Research Institute created the gel from combination of testosterone and another compound called Nestorone.
