Prevalence of Genital Tuberculosis in Infertile Women; a Study from a Tertiary Care Center in North India

ABSTRACT

Introduction: Female genitourinary tuberculosis (FGTB) is an important cause of infertility in women of reproductive age group. The disease remains undetected due to its asymptomatic nature and lack of sensitive tests. This study was conducted with the aim of detecting the prevalence of genital tuberculosis in infertile women. Material and methods: Endometrial curetting of 193 infertile women suspected of genital tuberculosis were taken laparoscopically and sent for histopathological examination, ZN staining, culture on LJ media and GeneXpert testing. Results: Out of 193 women, 13 were positive for Mycobacterium tuberculosis making the overall prevalence of FGTB in infertile women to the extent of 6.73%. Of these 11 presented with primary infertility while 2 patients presented with secondary infertility. The histopathological examination of all the samples was non-specific. No case of positive acid fast bacilli on ZN staining was observed. Comparison of culture and GeneXpert revealed that Xpert assay was more sensitive in detecting the positive cases. Conclusion: Our study concluded that FGTB is common in our population and women presenting with infertility should be evaluated for genital tuberculosis. A high degree of suspicion and combination of histopathological and microbiological tests are important methods for the detection of genital tuberculosis
