阴道pH值与阴道微环境的变化密切相关,当体内雌激素水平或阴道菌丛发生改变,而导致阴道微环境改变时,阴道pH值也会发生相应的变化。在对细菌性阴道病及绝经期症候群进行研究时,经常利用其作为观测指标,以便通过阴道微生态环境的变化了解疾病的结局及治疗效果。某些流行病学因素对其也有一定影响。 Vaginal pH and vaginal microenvironment changes are closely related, when the body estrogen levels or changes in vaginal flora, resulting in changes in the vaginal microenvironment, the vaginal pH will also change accordingly. In the study of bacterial vaginosis and menopausal syndrome, it is often used as a measure of observation in order to understand the outcome of the disease and the therapeutic effect through changes in the vaginal microflora. Some epidemiological factors also have some influence on it.
