The three reproductive tract pathogens are Mycoplasma, Chlamydia and Neisseria gonorrhoeae. These three main pathogens are the common causes of urinary tract infections, which are dangerous and highly contagious and can not only cause discomfort such as poor urination, burning sensation in the urethra and increased discharge, but can also affect the patient’s reproductive function. By performing these three tests, we can basically rule out the presence of infection, so that we can give the right treatment in time and not delay the disease.
