AbstractData based on total births from a geographically defined population with zygosity determined from blood samples and placentation and with data on the use of oral contraceptives routinely collected in early pregnancy showed no association between oral contraceptive use prior to pregnancy in either MZ or DZ twinning. Three mutually exclusive control groups of singletons were used to take account of age, parity and secular trends.

SummaryThe effect of Demulen (ethinyl estradiol 0.05 mg and ethynodiol diacetate 1 mg) and exercise on the level of plasminogen activators was studied in 25 women (12 controls and 13 contraceptive users).Plasma plasminogen activator level was increased by the use of the oral contraceptive and further increased by exercise. Urine plasminogen activator level was unchanged by the use of Demulen but, in both groups of subjects, was decreased by exercise.
