月经周期内阴道分泌物(白带)的容量和重量呈现规则变化,与基础体温相适应。测定白带量可推知子宫的易孕及不孕期。为确定这种方法是否可用于避孕,Schumather等令7名妇女在18次月经周期期间每天测定白带量。用作收集白带的收集管结构似注射器状,上有刻度以便测定容积。所有妇女测量结果都几乎与实验室测得的对照值相仿,故可认为受试者自测结果足够精确。白带的容量在基础体温升高前夕最大,大约相当于排卵前期的4～6倍。在观察的13个周期中白带量在排卵前1～2天或在排卵当日最多。正常情况下似乎阴道上部与阴道后穹窿所收集的白带量自然平衡。虽现尚未明确阴道分泌物的动 Menstrual cycle vaginal discharge (vaginal discharge) capacity and weight showed regular changes, and basal body temperature to adapt. Determination of leucorrhea can infer the uterine pregnancy and infertility. To determine if this method could be used for contraception, Schumather et al determined that seven women measured daily vaginal discharge during the 18 menstrual cycles. The collection tube used to collect the leucorrhea has a syringe-like structure with graduations to measure the volume. All women measured results that were almost comparable to those measured in the laboratory, so the subject self-test was considered accurate enough. The capacity of leucorrhea on the eve of basal body temperature rise the largest, equivalent to about 4 to 6 times the preovulatory. During the 13 cycles observed, leucorrhea volume was 1 to 2 days before ovulation or up to the day of ovulation. Under normal circumstances it seems that the amount of vaginal vaginal fornix and vaginal fornix collection of natural balance. Although it is not clear vaginal discharge of the move
