Objectives: Data regarding the association of Mycoplasma genitalium with infertility is scarce. This study was planned to look for the presence and association of M. genitalium in women with infertility. Materials and Methods: A prospective observational study was conducted on 100 cases of infertile women. The control group included 100 healthy fertile women. Samples of first void urine (FVU), endocervical swabs (ECS), and endometrial biopsies were subjected to polymerase chain reaction targeting MgPa gene to look for the presence of M. genitalium DNA. All endometrial biopsy samples were subjected to histopathological examination. A detailed clinical history of patients was taken, and all relevant investigations were recorded. Results: M. genitalium was found in 16% of women with infertility from either of the samples that is, FVU and/or ECS and/or endometrium biopsy, and none from controls. ECS and biopsy could detect the highest number of cases (27%). Asymptomatic cases predominated in the study and M. genitalium positivity (73.3%) was seen more in primary infertility. Tubal occlusion and disordered proliferative endometrium were demonstrated in 33% and 26.66% of M. genitalium positive cases respectively. Conclusions: The study shows an association of M. genitalium infection and infertility and suggests routine screening of this pathogen in patients with infertility.
