    Abstract:
    Symptoms may appear during the perimenopause, but it is often difficult to treat them at that time. Progestins are used to treat abnormal bleeding. Low dose hormone replacement therapy (HRT) or oral contraception are often used also. HRT can be used to maintain the bone density even in elderly women. Nevertheless, the treatment is often not taken for sufficient time. In order to improve compliance, a number of low dose HRT have been developed. For most patients these medications will preserve the bone mass, but data showing a fracture protection are missing. The exact role of HRT on cardiovascular pathologies is controversial. Observational data indicated a protective effect on atherosclerosis. But randomised studies contradicted these results: the latest randomised trial involving a continuous combined regimen of estrogen and progestin reported an increased risk in cardiovascular events as compared to placebo. It is still possible that estrogen decreases atheromatosis but that it increases the risk of thrombosis. SERM (Selective Estrogen Receptor Modulators) have agonistic and antagonistic proprieties to estrogens on selective tissues. They have a proven protective effect on bone and possibly also on cardiovascular system. Nevertheless, the risk of thrombosis seems to be similar to that of estrogens. The risk of breast cancer seems to be increased in long term HRT users but this subject is also controversial since discordant results have been reported. Furthermore, breast cancer mortality in HRT users seems to be lower than in non users.
