Fertilisation of human egg and sperm occurs in fallopian tubes. So tubes play a crucial role in transporting egg, sperm and embryo after fertilisation. Any pathology affecting tubes like pelvic inflammatory diseases, genital tuberculosis (kochs), post procedure scarring, hydro/pyosalpinx, to (tubo-ovarian) mass may affect tubal epithelium and hence the function. Affected tubes increase the likelihood of infertility and ectopic pregnancy as well. Tests like sonosalpingography (SSG) and hysterosalpingography (hsg) help us detecting tubal blocks. But they can give false positive reports, in which case laparoscopy is indicated to confirm blocked tubes. Some flimsy blocks can be opened but that may not be always possible. Those couples with bilateral tubal blocks can achieve pregnancy thru IVF (in vitro fertilisation) where fertilisation of egg and sperm happens in IVF lab, embryos are transferred in the womb which helps to achieve pregnancy.
