[Study of oral contraceptives action on blood folate levels (author's transl)].

In 95 women taking reduced-level-oral contraceptives and in 24 same-aged women controls, the measure of erythrocyte and serum folate led to the following conclusions: 1) Folate levels in women consuming the pill were generally found to be of the same range as those of controls. 2) No significant difference could be shown between results for different kinds of contraceptives.
