There is a persistent rumor that contraception by birth control pill may be at the expense of the figure. A new study refutes this perception. Since the 60s, the birth control pill on the market, and since then has been in the field of oral contraception much done. The hormone dose may now lies well below the are currently the market standard height, different products on the market, so that the doctor every patient the most appropriate drug to prescribe.Nevertheless, a simple Google search shows that the issue of pill and weight, "many women still burns on my mind. Researchers at Oregon Health & Science University were therefore of the problem and give in the Journal of Human Reproduction "all clear. "Issues around weight in humans are very difficult examinable, and previous research, whether oral contraceptives may now lead to weight gain or not, was not very fruitful so far," admits Alison Edelman, lead author of the study.
That is why many women are still unsure, give the figure for the sake of the pill and to become so out of the danger of unintended pregnancies. Rhesus monkeys with model CharakterDie researchers investigated to clarify the debate for a year a group of rhesus monkeys. Your reproductive system is similar to the human.
Unlike human studies, researchers can better control the animals - for example, in considering their food intake. At the beginning of the study, half of the animals was overweight, the other had normal weight. During the eight months of treatment the animals received an oral contraceptive to the weight of the Apes was adapted and then the dose is equivalent to take the women on the pill itself.
The researchers tracked the weight gain, food intake, exercise, body fat and muscle mass. At the end of the study, the weight of the normally sleek macaques had not changed. The obese, however, declined even (8.5 percent) because their metabolism had increased. Both groups had not changed their eating, activity or muscle mass.
"The study shows that concerns are based on weight gain by the pill more on fiction than facts," said Judy Cameron, one of the authors of the study. It appears that the perception of weight gain is the pill at the wrong conclusions: Since people over the years tend to increase, they give the drug to blame for this development.
