Your tubes are OK - you need to be checked for other causes of not conceiving like - egg formation failure or cervical factor/uterine defects/ diseases affecting the uterus - infections or semen disorders - the treatment depends on cause found. In some 30-40% there may be no cause found in which case stress may be a factor. If it is unexplained infertility or endometriosis/ blocked tubes - IVF is the answer. If it is simple semen defects - treatment with prepared semen can be done - after treating any possible infections. Treatment of egg formation failure is simple with medicines to achieve egg formation and timing the coitus with that.
