    Hormonal treatments impact high-density lipoprotein (HDL) cholesterol. Estrogens increase HDL, while progestogens decrease it, affecting cardiovascular disease risk. Careful selection of oral contraceptives is advised.

    Area of Science:

    • Endocrinology
    • Cardiovascular Health
    • Pharmacology

    Background:

    • High-density lipoprotein (HDL) cholesterol is a key indicator of cardiovascular disease risk.
    • Hormonal therapies, including oral contraceptives and treatments for gynecological indications, can influence lipid profiles.

    Purpose of the Study:

    • To investigate the effects of specific hormonal treatments on plasma high-density lipoprotein (HDL) cholesterol concentrations.
    • To compare the impact of different doses and types of estrogens and progestogens on HDL-cholesterol levels.

    Main Methods:

    • Plasma HDL cholesterol concentrations were measured in healthy young women.
    • Participants received 21-day oral treatments with norethisterone acetate or ethinyloestradiol.
    • Data were also collected from women using hormonal therapies for gynecological issues or oral contraceptives.

    Main Results:

    • Estrogens alone significantly increased HDL cholesterol concentrations.
    • Progestogens alone demonstrated a suppressive effect on HDL cholesterol.
    • Combined estrogen-progestogen therapies showed variable effects on HDL cholesterol, dependent on hormone composition and dosage.

    Conclusions:

    • Hormonal interventions have distinct and often opposing effects on HDL cholesterol levels.
    • Products significantly decreasing HDL cholesterol should be used cautiously due to potential cardiovascular disease implications.
    • The selection of oral contraceptives requires consideration of hormonal impact on HDL cholesterol alongside other risk factors.
