女性的月经出血天数、周期长度、卵泡期长度和黄体期长度与年龄和胎次有关，存在差异。表示总周期长度；无排卵周期;卵泡期和黄体期长度；以及在一年内无生育能力低下的女性月经和非月经出血的天数和强度。581名女性（3324个周期）未发现生育力低下（18-40岁），随访时间长达1年。妇女每天记录阴道出血和粘液排出。我们使用宫颈粘液高峰日作为排卵日和卵泡期最后一天的估计。我们使用按年龄和胎次分层的广义线性混合模型来描述月经周期参数。大多数妇女年龄<30岁（74.5%），非西班牙裔白人（88.6%）和未生育（70.4%）。平均经期6.2（1.5）天，中位数6天；周期长度30.3（6.7）天，中位数29天；卵泡期长18.5（6.5）天，中位数17天；黄体期长度为11.7（2.8）天，中位数为12天。≥30岁的未生育妇女与< 30岁的未生育妇女相比，周期更短（29.2天，95%可信区间（CI） 27.8, 30.7对31.5天，95% CI 30.8, 32.2），卵泡期更短（17.6天，95% CI 16.2, 18.9对19.6天，95% CI 18.9, 20.2）。在所有女性中，最长和最短月经长度>天、总周期>7天、卵泡期>7天、黄体期>3天的女性内部差异分别为11.6%、43.0%、41.7%和58.8%。我们的研究结果证实了与年龄和胎次相关的女性月经周期参数的可变性，同时也强调了女性在卵泡期和黄体期的可变性。
There is variability between women for days of menstrual bleeding, cycle lengths, follicular phase lengths, and luteal phase lengths, related to age and parity. To describe total cycle length; anovulatory cycles; follicular and luteal phase lengths; and days and intensity of menstrual and non-menstrual bleeding in women without known subfertility over the course of 1 year. 581 women (3,324 cycles) with no known subfertility (18–40 years of age) were followed for up to 1 year. Women recorded vaginal bleeding and mucus discharge daily. We used the peak day of cervical mucus as the estimated day of ovulation and the last day of the follicular phase. We used generalised linear mixed models stratified by age and parity to describe menstrual cycle parameters. The majority of women were <30 years of age (74.5%), non-Hispanic White (88.6%), and nulliparous (70.4%). The mean menses length was 6.2 (1.5) days, median 6; cycle length 30.3 (6.7) days, median 29; follicular phase length 18.5 (6.5) days, median 17; and luteal phase length 11.7 (2.8) days, median 12. Nulliparous women aged ≥30 years vs nulliparous women aged < 30 had shorter cycles (29.2 days, 95% confidence interval (CI) 27.8, 30.7 vs 31.5 days, 95% CI 30.8, 32.2) and shorter follicular phases (17.6 days, 95% CI 16.2, 18.9 vs 19.6 days, 95% CI 18.9, 20.2). Among all women, within-woman differences between the longest and shortest menses length >3 days, total cycle length >7 days, follicular phase >7 days, and luteal phase >3 days were found in 11.6%, 43.0%, 41.7%, and 58.8% of women, respectively. Our findings confirm variability between women of menstrual cycle parameters related to age and parity, and also highlight within-woman variability in the follicular and luteal phases.
