Contraceptive Steroids, age, and the cardiovascular system.
There is evidence that women who use oral contraceptives may be at slightly greater risk of cardiovascular complications as their age increased beyond 35 years. Popular opinion has held that these risks were largely estrogen-related. At the same time, however, postmenopausal women taking natural estrogen alone or in association with minimal amounts of progestogen have not exhibited these increased risk when compared with untreated control subjects. New clinical data indicate that there is a progestogen dose-related decrease in high-density lipoprotein cholesterol. There is also some evidence that relates progestogen dosage to morbidity rates from circulatory disease. Therefore the smallest dose of both estrogen and progestogen consistent with contraceptive efficacy and reasonable cycle control must be sought for all steroid combinations. This applies particularly to oral contraception for the woman beyond 35 years of age.
