Xu Li and Ma Hua were found to be infected with mycoplasma and chlamydia during their eugenics checkups, and were advised by their doctors to get regular treatment and wait until they were negative before trying to conceive. They believe that they are not feeling well and that mycoplasma and chlamydia infections will not affect their ability to have children. Studies have shown that Chlamydia trachomatis infection in mothers may lead to preterm delivery, premature rupture of membranes and low birth weight babies, and is also associated with neonatal conjunctivitis. Mycoplasma urogenitalis infections in pregnant women can cause preterm delivery, low birth weight babies, and endometritis. This shows that mycoplasma and chlamydia infections still have a negative impact on eugenics. Currently, pre-conception chlamydia and mycoplasma testing has been included as one of the important tests for eugenic screening. Of course, mycoplasma may also be present in normal people, and if there are no symptoms or diseases such as vaginitis, if you plan to get pregnant, our opinion is that it is better to cure it before getting pregnant, especially if your spouse also has mycoplasma infection.
