Testosterone may also lead to an unhealthy change in your total cholesterol. Research on testosterone and cholesterol has produced mixed results, however. HDL cholesterol is considered good for you, and LDL cholesterol is considered bad for you. Some studies suggest that testosterone can lower your HDL levels, which can contribute to higher levels of LDL cholesterol. This is because the main function of HDL cholesterol is to help your body remove excess LDL particles. Other researchers argue that there’s no definitive proof that testosterone interferes with the body’s cholesterol levels.
Screening for high cholesterol as part of a lipid profile is recommended for children and young adults. They should be tested once between the ages of 9 and 11 and then again between the ages of 17 and 21. Earlier and more frequent screening with a lipid profile is recommended for children and youths who are at an increased risk of developing heart disease as adults. Some of the risk factors are similar to those in adults and include a family history of heart disease or health problems such as diabetes, high blood pressure, or being overweight. When the youth's body mass index (BMI) is at or above the 85th percentile, cholesterol testing is recommended. For an obese youth (one whose BMI is at or above the 95th percentile), laboratory tests to measure cholesterol levels may be recommended every 2 years.
