This is an analysis of changes in menstrual cycle length and regularity occurring for a group of 211 women who had discontinued use of oral contraceptives. The analysis is based on prospectively recorded histories from the Menstruation and Reproduction History Program. Post-pill menstrual cycle length and regularity are compared with pre-pill averages. In the first post-pill cycle, there was an average increase of 6 days in cycle length. In subsequent cycles, however, cycle length and regularity were comparable to pre-pill norms in most cases.
这是对一组211名停止使用口服避孕药的女性月经周期长度和规律性变化的分析。该分析基于月经与生殖史项目前瞻性记录的病史。将停药后的月经周期长度和规律性与服药前的平均值进行比较。在停药后的第一个周期，周期长度平均增加了6天。然而，在随后的周期中，在大多数情况下，周期长度和规律性与服药前的标准相当。
