[Hormonal contraception and lipid metabolism. Prospective and retrospective studies of lipid metabolic parameters during the use of contraceptives].

Remarkable changes of several parameters of lipid metabolism were observed in a retrospective study of women, who had used different oral contraceptives for a longer time, in comparison with women without any hormonal contraception. In contrast, under the conditions of a prospective double-blind study no statistically significant alterations of the same parameters were seen under the use of two oral contraceptives different in dosage. Nevertheless, oral contraceptives should not be prescribed to patients with hyperlipidaemia.
