Study shows: Too much exercise can make women sterile
Physicians repeatedly point out how healthy regular exercise is. However, the correct dose is important. Because too much exercise can also damage your health. It can also affect the fertility of - slim - women, as a study shows.

Infertile through too much exercise
Exercise is healthy: Regular exercise can help reduce the risk of cardiovascular diseases such as high blood pressure. In addition, athletes are less likely to suffer from overweight or obesity. But as with so much in life, the right dose is important. Because too much exercise can not only be unhealthy, it can also make women sterile, as a study from Norway shows.

It doesn't depend on the sport
According to the "Nord-Trøndelag" study published years ago in the journal "Human Reproduction", too much exercise should make women sterile.

According to the Norwegian study, in which 3,887 participants took part, slim women who exercise five to seven times a week are 3.2 times more likely to have fertility problems, reports the portal "", which claims to be nine international Evaluated studies and spoke to medical professionals.

The longer the training takes, the higher the risk. Studies have shown that over 60 minutes of continuous training are bad for women's fertility.

Which sport is practiced is not decisive, the difference is the intensity. Women should never move to exhaustion.

Obese women benefit from exercise
However, apparently only slim women are affected. The body mass index (BMI) has a big impact. Obese women would therefore benefit from any sport in the form of higher fertility.

But why do obese women benefit from sport, but not slim ones? Miss Dr. Wibke Wilkening, specialist for gynecology and obstetrics explains the reduced fertility with a change in the hormones:

“Increased physical activity can have a negative impact on the hormonal axis between the brain, pituitary and ovary. In pronounced cases, the secretion comes to a complete standstill and the cycle does not occur, ”says the expert.

Do not train too often and not to exhaustion
However, it is not necessarily the sport itself that influences fertility, but the increased, but not covered, energy requirement:

"It is a well-known phenomenon that the body first shuts down the reproductive function and finally switches off below a - certainly individually different - minimum weight in the sense of self-preservation," explained Dr. Wilkening according to the portal.

And further: "Pregnancy is a stressful and energy-consuming state for an organism, which the body can no longer afford with minimal care, be it due to an eating disorder or increased consumption through massive exercise."

On "" there are a few tips for women that should help to avoid exposing yourself to increased risk: Do not train yourself to absolute exhaustion. Exercise no more than three times a week and no more than 60 minutes a day.

In addition, you should eat enough both before and after training to meet your energy needs. (ad)
