Researchers from the Norwegian University of Science and Technology first surveyed 3,000 women to learn about their fitness habits, such as exercise frequency, duration and intensity, and then counted the fertility after 10 years. The researchers found that women who exercised excessively were three times more likely to have fertility problems than women who exercised moderately.

Researchers say that excessive fitness has a greater impact on young women. Among the women under the age of 30 who exercise the most, 25% did not achieve any "results" in the first year of trying to get pregnant, while only 7% of women in Norway failed in the first year of trying to get pregnant.

One is a woman who exercises almost every day, and the other is a woman who is exhausted every time she exercises. Among them, women with both characteristics have the highest risk of infertility.
