Serum magnesium levels were determined by atomic absorption apectrophotometry in 224 Nigerian women attending the post-partem Family Planning Clinic of University College Hospital, Ibadan. The concentrations of serum magnesium in 44 control subjects were similar to those of 87 women who had been fitted with the Lippes loop. Serum magnesium levels were significantly lower (P smaller than 0.001) in 28 women taking Ovral 28 and in 65 women taking Norlestrin Fe in comparison with the control group.
