The effects were investigated of cyclical rhythm and hormonal contraception on serum fat-mobilizing activity, glycerol, cholesterol and whole blood glucose during 2 menstrual cycles in a group of normally menstruating young women and a second group of young women using hormonal contraception. A control group of normal young men was also investigated. There was no evidence of any change in mean level of any of the parameters measured, among the follicular, ovulatory and luteal phases. No cyclical pattern was discernable in the male subjects. The mean value for serum cholesterol concentration in women using hormonal contraception was higher than the value for the untreated human female group. The overall mean value for serum glycerol concentration in the women was significantly (0.01 > P > 0.001) higher than the mean value obtaining in the men.
