Doctors are urging more research into a little-known sexually transmitted infection that may be more common than thought.
However, it wasn't until 2019 that the first Food and Drug Administration-approved test for M. gen. became commercially available.
Similar to chlamydia and gonorrhea, M. gen. is sometimes asymptomatic, but it may lead to severe complications in both men and women.
In women, M. gen. is associated with cervical swelling, pelvic inflammatory disease, miscarriage, preterm birth, and infertility.
However, more research is needed to determine the longterm risks from M. gen infection, experts said.
