Vitamin-A levels have been determined in healthy non-pregnant women and in women taking synthetic steroids to suppress ovulation. A significant increase has been found in those receiving oral contraceptives. Further work is necessary to determine whether this may affect the fetus in patients who become pregnant shortly after discontinuing oral contraception.
已对健康未孕女性以及服用合成类固醇抑制排卵的女性的维生素A水平进行了测定。结果发现,服用口服避孕药的女性维生素A水平显著升高。有必要进一步研究,以确定这是否会对在停用口服避孕药后不久怀孕的患者的胎儿产生影响。
