It is advisable for cholesterol levels to be at adequate levels, both for seeking a pregnancy (either naturally or through assisted reproduction techniques) and for other important aspects such as having a good cardiovascular health.
In addition, if cholesterol levels are elevated in women, the time to achieve a pregnancy may be longer than if the levels are adequate.
Therefore, the best thing to do is to try to reduce cholesterol levels with a healthy and varied diet, avoiding bad habits such as smoking and exercising frequently.
