A brief history the benefits of boxers

But if you’re a guy looking to start or expand your family, when it comes to your underwear, briefs are bruisers and boxers help you dodge damage.

We told you a couple years ago that guys who wore boxers during the day and slept naked at night had 25 percent less DNA damage to their sperm than men who wore snug briefs around the clock. Well, we now know that boxers go a couple rounds further.

Researchers at Harvard’s T.H. Chan School of Public Health have found that not only are boxer wearers’ sperm healthier, but those guys have a 25 percent higher concentration of the healthy sperm, a 17 percent higher total sperm count and 33 percent more swimming sperm than men who wear tight-fitting briefs.

Sperm is sensitive to temperatures above 92 degrees. Your body is normally 98 degrees, and briefs keep the testicles close to the body. Boxershortsarelooser and cooler and get close to allowing for the au natural position of the testicles. In short, it’s no contest: Wear boxers for better sperm.

Catch up with HPV vaccine

“Ketchup, Catch Up!” is a children’s book written by Fran Manushkin about a young monkey named Ketchup who is slower than all the other monkeys. Because he’s so slow, he comes in last in every monkey activity. But if you or your daughter have been slow to get her HPV vaccines, she doesn’t have to come in last. You now have more time to catch up!

The Centers for Disease Control and Prevention now recommend that 11- or 12-year-old girls (and boys) receive two doses of HPV vaccine, which helps prevent cancers of the cervix, throat, vagina and penis. Unfortunately, fewer than half of girls in the U.S. ages 13 to 17 are up-to-date on the HPV vaccine series. And as of 2016, only 27 percent of males ages 9 to 26 had received at least one dose.

A recent study from Kaiser Permanente in Northern California that specifically looked at the risk for two types of cervical cancer suggests that, for girls and women, catching up with a three-dose series, starting their first dose from ages 14 to as late as 20, will still offer significant protection.

In addition, says the

CDC, if you’re a male who’s 13 to 21 and skipped the vaccine series, get it, along with those who are 22 to 26 and have a compromised immune system or are gay, trans- or bisexual.

Take advantage of your newfound window of opportunity to catch up!
