 The impairment of reproductive performance from adhesions may happen through many mechanisms, all of which usually stem from the distortion of the normal tubo-ovarian relationship.This distortion may prevent an ovum from traveling to the fimbriated end of the Fallopian tube.A meta-analysis in 2012 came to the conclusion that there is only little evidence for the surgical principle that using less invasive techniques, introducing fewer foreign bodies, or causing less ischemia reduces the extent and severity of adhesions in pelvic surgery.
