The FDA in America has given its approval for new tests that can positively identify an STI-causing bacterium called Mycoplasma genitalium. The FDA approval came after 12,000 samples were examined and the reliability of the test was confirmed. Mycoplasma genitalium is known to cause urinary and reproductive tract infections. Until present, however, there was no reliable way to test for its presence. The early treatment of Mycoplasma genitalium infections is very important because in the long run, these could contribute to infertility or pregnancy complications.
