While there are gender differences in cholesterol levels, they are not associated with different levels of risk for a given value of cholesterol, according to the New York Times. However, a separate category of blood lipid, known as triglycerides, does show differential risk based on gender.
Cholesterol and triglycerides are two kinds of lipids, a class of chemical that include oils and fats, explains Mayo Clinic. Both cholesterol and triglycerides circulate in the blood, but cholesterol is used to build hormones and cell membranes, while triglycerides are used to store excess calories.
Men and women have differing levels of cholesterol due to how testosterone and estrogen affect cholesterol production. However, this difference does not affect the point at which cholesterol levels become dangerous. A cholesterol chart for health risk is not subdivided by gender, as stated by MedlinePlus.
On the other hand, it appears that high triglycerides are a much more important risk factor for stroke in women than in men, reports ScienceDaily.
