自然周期自然周期 规律的月经周期是性成熟的主要特征。未受药物及外界因素影响的、受人体内源性激素调节的月经周期视为自然周期。月经周期是在复杂的神经内分泌调节下进行的，涉及中枢神经系统、垂体、卵巢及子宫等器官，其中任何一个环节发生异常都可能导致自然周期的紊乱。月经周期乃是一次卵细胞成熟为受精和受孕做准备的历程。为了受精卵的种植，子宫内膜功能层发生了一系列的改变，若受孕成功则妊娠继续而月经停止；如没有受精卵种植，则子宫内膜的功能层剥脱，随月经血流出，即月经来潮。下一月经周期重复为受孕做准备。月经周期的计算是从此次月经的第1天到下一次月经的前1天。一般为28～30天，正常周期的范围是21～40天。经期是指月经血持续的时间，一般为5～7天。月经周期可分为3个阶段：卵泡期、排卵期和黄体期，卵泡期可有长短，但黄体期较稳定，为14天±2天。在月经初潮以后、月经停止以前或严重的疾病期间可能导致短期的月经不规律。
