Bacterial vaginosis generally does not have a particularly large or obvious impact on conception, but it can indeed potentially affect the process of conception. This is primarily because when bacterial vaginosis occurs, there are usually a significant number of inflammatory cells in the vagina or the cervix. These inflammatory cells may affect sperm, thereby potentially impacting the process of conception. Of course, when bacterial vaginosis is present, it is generally recommended to treat it before pregnancy. This is mainly because if bacterial vaginosis exists during pregnancy, there may be an increased risk of bleeding, miscarriage, or premature birth. Therefore, it is usually advised to treat bacterial vaginosis before planning to conceive.
