Diagnostic imaging of fertility disorders

It is estimated that as many as 15% of married couples are affected by fertility disorders. The number of such couples seeking medical help has increased dramatically in the past 10 years due to both relative and absolute factors. The increase in population, the rising rate of sexually transmitted diseases, and the reduced availability of adoptable infants all contribute to the magnitude of this problem. The role of diagnostic imaging in the effective and compassionate care of couples desiring offspring is the subject of this review. Infertility is a disorder of a couple, not of two individuals. The diagnostic evaluation, therefore, must include both partners. Hysterosalpingography and ultrasound constitute the mainstay of the evaluation of the female member. The various techniques and complications of hysterosalpingography are reviewed. The normal appearance of the uterine cavity together with a review of the numerous anomalies and variations that might be encountered are presented. Along similar lines, the possible filling defects, synechiae, postoperative changes, and other alterations that may be encountered in imaging the uterine cavity are described. Evaluation of the fallopian tubes is of paramount importance, primarily to assess patency but also to assess the possibility of patent but diseased salpinges or disease of the surrounding peritubal tissue. Recently, interventional techniques using radiographic and sonographic control have been developed and are beginning to demonstrate promising results in the management of fallopian tube obstruction. These procedures, adapted from previously established radiographic interventive techniques, are discussed. The role of diagnostic imaging of the male partner is of lesser magnitude. Clinical assessment and semen evaluation generally permit adequate assessment of the male factor. Occasionally, however, vasography and seminal vesiculography are called into play. More frequently, sonographic evaluation to establish the presence of varicoceles is necessary. Such techniques are reviewed, as well as the interventional approaches for ablating varicoceles. The application of conventional and transvaginal sonography in the management of gynecologic fertility disorders is reviewed. Follicular monitoring, guided follicle aspiration, assessment of the status of the endometrium, guided embryo transfer and tubal cannulation, and evaluation of other pelvic disorders are significant factors in the appropriate management of the infertile couple.(ABSTRACT TRUNCATED AT 400 WORDS)
