Background: To evaluate the prevalence of Müllerian anomalies (MAs) among infertile women came for fertility treatments (intrauterine insemination or IVF (In vitro fertilization) cycles. Aim: To calculate the prevalence of mullerian anomaly and each subtype among infertile women. Methods: This is a retrospective observational study based upon a cohort of infertile women, who underwent hysteroscopy and laparoscopy as part of the basic infertility workup from 2018 to 2019, at department of Reproductive Medicine in IGIMS, Patna. Results: A total of 160 women were included in the study. The prevalence of mullerian anomaly was 8.13% (n=13). The prevalence of different subtypes among women with mullerian anomaly were: septate uterus 53.85% (n = 7), arcuate uterus 23.08% (n = 3), bicornuate uterus 7.69% (n = 1), unicornuate uterus 7.69 % (n = 1) and didelphys uterus 7.69% (n = 1). We did not find any case of uterine hypoplasia/agenesis or unclassified type. Women with mullerian anomaly who achieved pregnancy were: 38.46% (n = 5). Highest pregnancy rate was associated with septate uterus after hysteroscopic correction, at 42.86% (3/7). Conclusions: The prevalence of mullerian anomaly among infertile women may be considered as low. The most common mullerian anomaly is septate uterus in women with infertility.
