Fecal hormones

This dataset includes the data for our third analysis, which examined fecal glucocorticoids (fGC), fecal estrogens (fE), and fecal progestogens (fP) during PPA as a function of the number of months to sexual cycle resumption, or during the various phases of the sexual cycles (early or late follicular and luteal) as a function of the number of cycles to conception. For fGC and fE we had a total of 5,470 hormone samples collected between 2000 and 2014 for 138 females during 549 IBIs. Of these samples, 4,150 fecal samples were collected during PPA, and 1,320 were collected during cycling. Each female contributed fecal samples from an average of 4 IBIs (range: 1-11) with an average of 10 hormone samples per IBI (range: 1-55) and an average total number of 40 samples per female (range: 1-145). For fP, we had a smaller sample size of 4,095 hormone samples collected between 2003 and 2014 for 130 females during 456 IBIs; 2,922 were collected during PPA and 1,173 during cycling. Each female contributed samples from an average of 3.5 IBIs (range 1-8), with an average of 9 (range 1-47) samples per IBI, for an average total number of 32 (range 1-141) samples per female.本数据集涵盖本研究第三次分析的全部相关数据，本次分析以两项维度开展：其一，以距性周期恢复的月数为自变量，探究产后乏情期（PPA）内的粪便糖皮质激素（fecal glucocorticoids, fGC）、粪便雌激素（fecal estrogens, fE）与粪便孕激素（fecal progestogens, fP）水平；其二，以距受孕的周期数为自变量，探究性周期各阶段（卵泡早期、卵泡晚期及黄体期）的上述激素水平。针对fGC与fE，研究团队于2000年至2014年间，为138头雌性个体在549次产仔间隔（IBI）中共采集总计5470份激素样本。其中4150份粪便样本采集于PPA阶段，剩余1320份采集于性周期循环阶段。每头雌性个体平均贡献4次IBI的粪便样本（样本范围：1~11次），单次IBI内平均采集10份激素样本（范围：1~55份），单头雌性个体的平均总样本量为40份（范围：1~145份）。针对fP，研究团队于2003年至2014年间，为130头雌性个体在456次IBI中共采集规模更小的4095份激素样本。其中2922份样本采集于PPA阶段，1173份采集于性周期循环阶段。每头雌性个体平均贡献3.5次IBI的样本（范围：1~8次），单次IBI内平均采集9份样本（范围：1~47份），单头雌性个体的平均总样本量为32份（范围：1~141份）。
