4. Mycoplasma Genitalium
In 2007, a prominent study of U.S. adolescents found that a little known STD, mycoplasma genitalium had surpassed gonorrhea in prevalence. Most cases of M. genitalium don’t cause symptoms and it had been difficult to identify until more recent technology became available. While the emerging research is still unclear, it is thought that MG is associated with serious long-term consequences, including infertility from pelvic inflammatory disease. MG, like gonorrhea and chlamydia, may emerge as a major cause of cervicitic in women, and nongonococcal urethritis in men.
