Overview
Classification
Historical Perspective
- Mycoplasma genitalium is the 11th Mycoplasma species of human origin.[1]
- In 1980, 13 men were tested for non-gonoccal urethritis (NGU). Mycoplasma genitalium was isolated from 2 of those 13 men.[2][3][4]
- In the early 1990s, polymerase chain reaction (PCR) was developed, which allowed for diagnosis of Mycoplasma genitalium.[2][4][5]
- Since 1993, the role of Mycoplasma genitalium as a cause of non-gonococcal urethritis has appeared in literature following the advances in polymerase chain reaction (PCR).[5]
Pathophysiology
Pathogenesis
Mode of Transmission
- Mycoplasma genitalium is recognized as a sexually transmitted disease (STD) with the mode of transmission being through direct genital-to-genital contact and subsequent inoculation of infected secretions. Transmission of Mycoplasma genitalium has also been implicated in penile-anal intercourse. [2]
- Mycoplasma genitalium is less likely to be transmitted via oro-genital contact, as carriage in the oropharynx is low. [2]
- Whether or not Mycoplasma genitalium is vertically transmitted from mother to newborn is yet to be studied. However, the bacterium has been isolated from the respiratory tract of newborns. [2]
Incubation Period
The incubation period of Mycoplasma genitalium is unknown yet.[6]

Epidemiology and Demographics
Risk Factors
There several risk factors that have been identified with Mycoplasma genitalium infection. These risk factors include:[2][4][7]
- High risk sexual behavior, defined as having >3 new sexual partners in the past year
- Being engaged in sexual contact with persons with STDs, particularly Mycoplasma genitalium
- Non-white race
- Having a black partner
- Young age (<20 years old)
- Smoking
- Having less than high school education
- Having an annual income of less than $10,000
- Risk factors specific to females includes:
- Frequent douching
- Proliferative phase of the menstrual cycle
- History of spontaneous miscarriage
- Undergoing procedures that breach the cervical barrier
- Use of Depo-Provera for contraception
