We look through hundreds of studies every week at Men’s Health, and we’re always impressed at some of the strange stuff scientists spend time and money researching.

For example, Swiss researchers recently wanted to explore whether women think guys with surgically corrected hyposadias—a birth defect in which your meatus, or urethral opening, is on the underside of your penis—have regular-looking rods.

As part of the study, the scientists asked female participants to rank which factors they considered most important in an attractive penis. File this under “requests that are only acceptable in a lab setting.”

Turns out women don’t love any particular penis trait. They rated overall genital appearance as the most important factor, followed by pubic hair.

Super precise characteristics like penile length, look of the scrotum, and position and shape of the meatus rounded out the least important qualities:

“Women perceive a wide variation of penile appearances as normal or good-looking,” says study author Norma Ruppen-Greeff, M.Sc.

Nothing mind-blowing, but here’s the nice thing about the results: While you might feel self-conscious about a schlong that comes up short or balls that hang a little low, women don’t focus on any one area when they judge your Johnson—they look at the total package.

So you just need to freshen up. You always look your best after a haircut, right? Researchers from Indiana University found that 75 percent of women say they would like their guy to trim down below.

Sprucing up your schlong can also make you feel sexier, boosting your confidence both in and out of the sack, the study says
