It is not advisable to become pregnant with yeast vaginitis, primarily for the following reasons:

First, yeast vaginitis can affect the vaginal pH, impact sperm motility, reduce sperm quality, and make it difficult for fertilization to occur.

Second, the yeast can spread through the cervix and cause infection of the amniotic membrane, which may lead to intrauterine infection or rupture of the membranes, easily causing miscarriage or premature birth.

It is recommended to try to conceive after treatment has returned the condition to normal. It is essential to maintain good hygiene habits regularly, such as frequently changing and sun-drying underwear, boiling them in hot water. Additionally, under favorable conditions, engaging in more physical activities like yoga and running can help boost the body's resistance.
