It is highly recommended to consult with a specialist before doing any diagnostic tests. After submitting to a semen analysis male patients with abnormal results are first consulted/examined by a urologist, experienced in treating male infertility. The urologist refers the patient for further diagnostic testing and determines the best course of treatment once the results come out. The treating physician can also refer the patient for a consultation with a different type of specialist if needed – e.g. an endocrinologist/nutrition specialist, psychologist, sexologist and/or a geneticist.
