[Extended oestrogen-progestin contraceptive regimens: towards a contraception without menses].
Women's attitude concerning menstruations is changing towards achieving extended cycles with few or even suppressed menses, in view of the unpleasant perimenstrual bleeding, pain and discomfort pattern that may accompany menstruation. Use of combined oral estrogen-progestin contraception in extended "cycles" of 3, 6 and 12 or more months is now under active study. Extended cycle contraception is abided by a better compliance than conventional cycle contraception with ensuing optimized contraceptive effectiveness. Hypothetically, transdermal or transvaginal combined contraception could be used in extended cycles. Tolerance is comparable for both methods and unpredicted bleeding, initially more frequent during long cycle treatment tends to become less frequent after about 6 months a compared with conventional cycles. Usual safety parameters appear to be similar under both contraceptive modalities. Comfort and well being brought by extended cycle use (5 to 10 times fewer days of bloating or perimenstrual pain) allow to estimate that, according to acceptability studies, 10 to 40 percent of women of reproductive age would currently choose extended cycle contraception.
