Plasma lipids in women using progestogen-only oral contraceptives

British Journal of Obstetrics and Gynaecology
M H Briggs, M Briggs

Abstract

Using a strict protocol, in an attempt to avoid confounding factors, healthy women were assigned at random to a continuous daily dose of either 30 micrograms levonorgestrel or 350 micrograms norethisterone. Volunteers were either aged 40-45 years, or were less than 30 years and 8-12 weeks post partum. Blood plasma lipids and lipoproteins were measured on specimens collected in the fasting state before treatment, then every month during progestogen treatment. After 6 months there was a small increase in plasma triglycerides, especially in older women, and also in a non-lactating younger group. Changes in lipoprotein-cholesterol fractions were insignificant, though there were significant pretreatment differences between the various groups.

ApoE, Lipids & Cholesterol

Serum cholesterol, triglycerides, apolipoprotein B (APOB)-containing lipoproteins (very low-density lipoprotein (VLDL), immediate-density lipoprotein (IDL), and low-density lipoprotein (LDL), lipoprotein A (LPA)) and the total cholesterol/high-density lipoprotein (HDL) cholesterol ratio are all connected in diseases. Here is the latest research.
