In general, mycoplasma infections do not cause menstrual irregularities when the inflammation is controlled clinically and in a timely manner. However, if the mycoplasma infection is not intervened or treated and causes a retrograde infection, such as causing inflammation of the uterine body or leading to pelvic inflammation, in which case, especially when inflammation of the ovaries occurs, the egg cells will be destroyed, which will clinically lead to irregular menstruation. It is recommended to do gynecological examination to find out whether there is pressure and pain in the uterine adnexa, and through the examination of vaginal secretions and cervical secretions, it is recommended that azithromycin be preferred if there is a mycoplasma infection, or through the culture of mycoplasma plus drug sensitivity test to decide the type of antibiotic to use, and then this situation will often turn to normal.
