If you are undergoing tests in an Assisted Conception Unit the semen analysis report will sometimes recommend if IVF or ICSI is required if you were to come through for treatment.  As the semen analysis is within normal parameters and from the other medical history you have supplied the reason you have not yet conceived is still unexplained.  It is still possible for you to conceive naturally and it is sensible to keep trying while you are waiting for further advice from your Doctors.
