Role of latent genital tuberculosis in repeated IVF failure in the Indian clinical setting.
Genital tuberculosis is reported to be a major pelvic factor causing infertility in Indian women and often exists without any apparent signs and symptoms. The role of latent tuberculosis in repeated IVF failure in unexplained infertility is examined. 81 women with unexplained infertility having repeated IVF failure tested for Mycobacterium tuberculosis using PCR, ZN staining and BACTEC-460 culture were selected. Fresh IVF-ET or frozen embryo transfer (FET) was attempted on patients successfully treated with anti-tubercular drugs (ATD). ATD-treated fresh cycles (group A1) and frozen cycles (group B1) were compared to previously failed fresh cycles (group A2) and FET attempts (group B2), respectively. Main outcome measures were gonadotropin required, terminal E2, number of oocytes retrieved, fertilization rate, embryo quality, endometrial thickness and sub-endometrial blood flow (V(max)). Gonadotropin required in group A1 was significantly less as compared to group A2. Number of oocytes retrieved and grade I embryos, endometrial thickness and V(max) were significantly higher in group A1. Endometrial thickness and V(max) were significantly increased in group B1 as compared to B2. The study indicates that latent tuberculosis should be considered in young Indian patients presenting with unexplained infertility with apparently normal pelvic and non-endometrial tubal factors and repeated IVF failure.
