“…Our results are consistent with previous studies that used PCR-based techniques, which have detected this organism in 11%-29% of men with urethritis and in 0%-8.5% of control subjects [6][7][8][9][10][11]26], and in 0.8% of asymptomatic men in Japan recruited from a general medicine clinic [27]. Differences in our study and previous studies include the specimen tested (urine vs. urethra), patient population studied, and the detection techniques for M. genitalium.…”

Chlamydia trachomatis and Neisseria gonorrhoeae are universally acknowledged as urethral pathogens, yet the etiology in the majority of cases of urethritis is unclear. Our case-control study assessed the association of Mycoplasma genitalium, Ureaplasma urealyticum, and other potential pathogens with acute nongonococcal urethritis (NGU) in heterosexual men presenting to an urban sexually transmitted diseases clinic. M. genitalium was detected in 27 (22%) of 121 NGU case patients and in 5 (4%) of 117 control subjects (P<.01). Although C. trachomatis was detected in 36 (30%) of 121 NGU case patients and in 4 (3%) of 117 control subjects (P<.01), only 3 men with NGU were infected with both C. trachomatis and M. genitalium. U. urealyticum was not associated with NGU. By multivariate analyses, controlling for age, race, history of prior urethritis, and chlamydial infection, M. genitalium was associated with a 6.5-fold increased risk of urethritis (95% confidence interval, 2.1-19.5), which supports a role of this organism in the etiology of NGU.

“…8 Thus, a prevalence of 2.3% among women in our study is within the expected range as our population consists of a mixture of high and low-risk individuals, as is seen in the descriptive data of the population (table 1). For males, a low prevalence of 1.1% is also in line with other studies showing a prevalence of 1.1% in men attending a Department of Medicine for check-up 27 in Japan and prevalences of 0.8% to 8.5% among asymptomatic men seen in STD clinics. [2][3][4][5][6][7] The low coinfection rate with C trachomatis among both men and women is somewhat surprising, but in line with results found in other studies.…”

Background: Mycoplasma genitalium has been shown to cause urethritis in men and cervicitis in women and may also be a causative agent in female infertility. Objective: To estimate the prevalence of urogenital M genitalium infection and identify sexual behavioural risk factors in the general population. Methods: Participating individuals were 731 men and 921 women aged 21-23 years and not seeking the healthcare system because of symptoms. They answered questionnaires on sexual behaviour and provided samples for M genitalium testing. Results: In women aged 21-23 years, the prevalence of infection was 2.3% (21/921) and in men of the same age it was 1.1% (8/731). For both sexes, an increasing number of partners was associated with a greater chance of being infected. Among women a shorter duration of a steady relationship and having a partner with symptoms was associated with being infected, and for men younger age at first intercourse was associated with M genitalium infection. Conclusions: We conclude that the prevalence of infection in the general population is too low for populationbased screening. However, the development of test algorithms based on behavioural risk factors is a promising alternative.

“…Another report showed that 1.1% of asymptomatic Japanese men were positive for M. genitalium. 7 In reports from New Orleans and Denmark, 7% and 9%, respectively, of asymptomatic men were positive for M. genitalium. 8,9 The reasons for the differences in the data between Japan and other countries are not clear.…”
