Final answer:
Estrogen and progesterone have a favorable impact on lipid metabolism in premenopausal women. They increase HDL levels and decrease LDL levels, which helps prevent cardiovascular diseases.
Step-by-step explanation:
Estrogen and progesterone have a favorable impact on lipid metabolism in premenopausal women. They increase HDL (high-density lipoprotein) levels and decrease LDL (low-density lipoprotein) levels. Higher levels of HDL help remove LDL from the arteries, preventing the build-up of plaque and reducing the risk of cardiovascular disease. This positive effect on lipid metabolism contributes to better overall cardiovascular health.
