The increased exposure to semen (~7 pH) during baby-making can tax the vagina’s self cleaning and balancing mechanisms. Additionally, not long after the fertile window, the vaginal ecosystem pH becomes more neutral (~7 pH) during your period. Constant exposure to a neutral pH (~7 pH) can eventually overwhelm the acidic environment of the vagina and may lead to odors, or even serious diseases (bacterial vaginosis, vaginitis, postpartum infections), increased STD/HIV rates, preterm labor (van de Wijgert et al., 2014), and perhaps even increased levels of preterm birth (Critchfield et al 2013). Women with disruptions in the vaginal ecosystem and pH have recently been reported to have decreased fertility and a longer time to successful conception. Delays in your journey to pregnancy become real when pH is out of kilter.
