Under normal circumstances, the vagina has a relatively safe environment where the microbial flora is balanced and the pH level is also balanced. This suitable environment that allows sperm to temporarily reside and pass through is very important. Once this environment is disrupted, infertility can easily occur.

If one suffers from yeast vaginitis, the change in the vaginal pH also inhibits the motility of sperm. Inflammatory cells can also engulf sperm and reduce sperm motility. Candida albicans can agglutinate sperm, and the pain during intercourse and decreased libido that occur with inflammation can all affect pregnancy.

Therefore, if one is diagnosed with yeast vaginitis, it is crucial to treat it promptly. Yeast thrives in moist environments, so it is important to frequently change and sun-dry underwear.
