Effects of Estrogen Therapy on Hormonal Functions and Serum Lipids in Men with Coronary Atherosclerosis

Abstract
Middle-aged men with coronary atherosclerosis were studied before and at intervals after initiation of estrogen therapy over a 12-month period. Serum lipid studies during treatment revealed consistent increases in phospholipid and α-lipoprotein cholesterol and decreased β-/α-lipoprotein cholesterol ratios. Concomitant endocrine studies demonstrated the expected testicular depression without apparent detriment to thyroid or adrenal function.
