Hysterometry, a method for quantitative evaluation of the effect of pharmacologically active agents on the myometrium, has been applied to determine the effect of an oral contraceptive on uterine tonicity. Hysterometry was performed on the first day of each of two consecutive menstrual periods in 5 dysmenorrheic women. During the second cycle the women were given ethinylestradiol 50 microgram and lynestrenol 1 mg per day for 22 days. After the intake of this oral contraceptive, uterine tonicity decreased in all women, the decrease being accompanied by relief of dysmenorrheic pain.
子宫测量法是一种定量评估药理活性剂对子宫肌层作用的方法，已被用于确定口服避孕药对子宫张力的影响。对5名痛经女性在连续两个月经周期的第一天进行子宫测量。在第二个周期中，这些女性每天服用50微克炔雌醇和1毫克利奈孕酮，持续22天。服用这种口服避孕药后，所有女性的子宫张力均下降，这种下降伴随着痛经疼痛的缓解。
