Men Masturbated For Science, And Here's What Came Of It

 They say variety is the spice of life, and provocative new research by scientists in Ohio suggests that that holds true in the world of human sex and reproduction. With the help of 21 men and some porn videos, The College of Wooster researchers showed that guys ejaculate faster and produce more, higher-quality sperm when they masturbate to a "novel female stimulus." In other words, they really get off with a hot woman they've never previously encountered. The finding doesn't mean that men are somehow programmed to cheat on their girlfriends and wives. It may suggest that men have evolved such that it's easier for them to have sex with (and impregnate) other women without their usual partners finding out. As study co-author Dr. Laura K. Sirot, assistant professor of biology at the college, told The Huffington Post in an email, "Our study does not suggest anything about whether monogamy was favored or disfavored by natural selection. However, the results of this study and other studies of human differential ejaculation behavior suggest that extra-pair (or extramarital) copulations may have occurred in our evolutionary past." In addition to providing new insights into evolutionary biology, the finding may lead to better detection and treatment of male infertility. When men see a doctor about fertility problems, they often provide semen samples collected while masturbating to porn. And since it features novel women, "the ejaculates produce...

AbstractBackgroundFunctional hypothalamic amenorrhea (FHA) is a form of chronic anovulation not due to identifiable organic causes and with adverse health consequences. The identification of women with this disorder or the precocious identification of women at risk is based on the knowledge of lifestyle risk factors or behaviors such as stress, weight loss, and excessive physical exercise that are known to negatively impact gonadal axis activity.Methods In this overview, we described the most common forms of FHA, in particular stress-induced amenorrhea and overtraining-induced amenorrhea. In addition, although its mechanis...

Bradley Goldman has filled out a size large T-shirt his whole adult life. As a bodybuilder, he knew that a steady stream of lean, bland proteins, heavy weights and steroids would make his muscles pop. But over the past six months, Goldman, a fitness and nutrition consultant in Los Angeles, has watched his jacked physique soften and shrink. “I cracked a couple of weeks ago, and I had to buy a shirt a whole size smaller,” he says. He tried it on for his wife Brittany, and it hung loose on his frame. “I just kind of shook my head,” he says. He knew she saw the changes too. Goldman, now 30, began takin...

igi L Abstract It is universally accepted that lifestyle interventions are the first step towards a good overall, reproductive and sexual health. Cessation of unhealthy habits, such as tobacco, alcohol and drug use, poor nutrition and sedentary behavior, is suggested in order to preserve/improve fertility in humans. However, the possible risks of physical exercise per se or sports on male fertility are less known. Being "fit" does not only improve the sense of well-being, but also has beneficial effects on general health: in fact physical exercise is by all means a low-cost, high-efficacy method for prev...

Authors: Schuppe HC, Köhn FM Abstract The identification of potential environmental hazards may be clinically relevant in the diagnosis of male infertility. Knowledge about these factors will improve prevention of fertility disorders. Apart from drugs or factors related to lifestyle such as alcohol and tobacco smoke, various environmental and occupational agents, both chemical and physical, may impair male reproductive function. Reproductive toxicity may evolve at the hypothalamic-pituitary, testicular, or post-testicular level; endpoints comprise deterioration of spermatogenesis and sperm function as well as ...
