[Lowering effect of estrogen replacement treatment on immunoglobulins in menopausal women].

Similarly to the results reported in pregnancy and during oral contraceptive use, estrogen replacement therapy (ERT) had a lowering effect on serum immunoglobulins (IgG, IgA, IgM) of 20 postmenopausal women with a mean age of 52.2 years, in parallel with an increase in the blood values of estradiol (E2).
