Is it possible that my husband’s sperm could be causing me to have frequent vaginal infections?
Yes and no. It’s not so much the sperm as it is the semen. Bacterial vaginosis (BV) is the most common vaginal infection that can occur when the microbiome is out of balance, and the pH persists in a more alkaline state. There is a long list of risk factors for how this occurs, but most commonly, exposure to blood during menstruation or semen during sex. BV is caused by a bacteria called Gardnerella which can go undetected when the pH is more acidic, but then during an alkaline state, it can bloom and become problematic. It may require more aggressive treatment to eradicate so that it doesn’t come back after sex. There are also ways to acidify the vaginal flora quickly after sex so that a vaginal infection doesn’t occur. Talk to your doctor to discuss your options.
