The equilibrium of endometrial flora and existing bacteria is key to reproductive success.

Some bacteria, like lactobacilli, are present in the endometrium but sometimes a dysbiosis occurs and pathogenic bacteria begin to grow. In these cases, implantation failures and repeated miscarriages may occur.

On some occasions, inflammations or chronic endometritis can be detected in the uterus, and even if they are mild, they must be treated because they also diminish the chances of becoming pregnant significantly.

Treating these conditions with antibiotics and probiotics in case of alterations increases the possibility of a successful pregnancy.
