Abstract

Introduction. Female genital schistosomiasis (FGS), infection of Schistosoma spp. trematode in the gynaecological apparatus, is the most neglected sexual and reproductive health condition in sub-Saharan Africa with an estimated of 20-120 million cases. The ectopic entrapment of Schistosome eggs after oviposition can occur in 0.5% of cases in fallopian tubes and ovaries.The case. We report a case of 38-years-old woman assessed for a 10 year history of infertility. On ultrasound, multiple cystic formations were observed in the ovary. Histology after oophorectomy to exclude malignancy showed granulomatous formations surrounding Schistosoma spp. eggs in proximity of corpus luteus and haemorragicum.Discussion. Ectopic Schistosome oviposition, seen in the ovary and fallopian tubes as in our case, can be a potential cause of reproductive organ damage and complications such as infertility, ectopic pregnancy, miscarriage, premature birth, low birth weight, and even maternal death.Conclusions. More studies are needed on ovarian FGS and its impact on women fertility to guide specific interventions targeting vulnerable population of childbearing age, contributing to the NTD WHO 2030 aim of eliminating schistosomiasis as a matter of public health.
