Fifty-eight postmenopausal women were followed with respect to subfractions of high-density lipoprotein during 3 cycles of unopposed estrogen. The women received either levonorgestrel, medroxyprogesterone acetate, or natural progesterone during the last ten days of the treatment period. Both progestogens significantly lowered HDL cholesterol, whereas natural progesterone had no effect on HDL levels.
