What rationale is provided for avoiding douching immediately after sexual intercourse during pregnancy?

The rationale for avoiding douching immediately after sexual intercourse during pregnancy centers on the potential risks associated with introducing bacteria into the vaginal environment. Douching can disrupt the natural balance of bacteria and pH levels in the vagina, which are especially important during pregnancy for maintaining a healthy reproductive system.

Introducing external substances through douching can lead to infections rather than prevent them, as the action may push bacteria further up into the reproductive tract. This concern is exacerbated during pregnancy when changes in hormonal levels and the body's immune response might make a woman more susceptible to infections. Therefore, rather than being an effective method for preventing infections, douching poses a risk and is discouraged.

While it may be a practice some people adopt, obstetricians do not routinely recommend it, particularly not immediately after intercourse, as the risks outweigh any perceived benefits to hygiene or cleanliness. Maintaining pelvic hygiene is better achieved through gentle washing with water and avoiding interventions that disturb the natural flora.
