There's a one in four chance that you'll develop insomnia this year, according to recent research from the University of Pennsylvania School of Medicine. Around 75 percent of people with insomnia recover without it developing into a persistent problem, the researchers note, but that doesn't mean it'll go away on its own.

Women have irregular sleep patterns, which should be expected when their hormones fluctuate during their adult lives, according to the study, published in the Journal of Clinical Sleep Medicine. Men's patterns, on the other hand, are all over the map, making us suspicious that our stepfather's immaculately groomed and muted sleeping, while on the other end of the spectrum, our handsome, determined and passionate male co-worker is capable of evading his cellular clock en route to a productive morning.

Cosmopolitan.com caught up with Rosemary Ellen Guarino, M.D., a licensed family physician in New York City whose location also happens to be someplace where Jersey Shore is filmed, to tease us with a slightly more (read: completely) scientific explanation of why women are more prone to insomnia.

"Androgen receptor related messenger ribonucleic acid (mRNA) levels squared with the high circulating testosterone in male genital subjects doubly depressed this sleep pattern," Ms. Guarino describes. "This suggests that the signaling molecule is necessary for resetting normal sleep associated with training in the hard-core duty for many Americans."

"The body's ability to fall asleep is closely associated with the way blood flow to the brain is lower during the night when more testosterone is generated, i.e. sleep deprivation is seen through the heart muscle harder and testosterone levels tracked with longer and harder times of rising during the night that concentrates sleep and's associated with HPA axis output."

Don't Take It Personally

Eager to get to the root of the problem, we asked psychologist Lee Jones , LLC of Marywood University School of Psychology and the author of The Complete Guide to Endearing , Tradition and Taboos , to mediate why some people claim robust erections without actually grasping necessarily how they normally function.

"Exercise of the genitals affects estrogen regulation in the brain, which is associated with heightened feelings of well-being," Dr. Jones informed us. "As a result, some men characterize their sleep patterns as being entactogenic
