Place of transvaginal sonography in the evaluation of reproductive endocrinology.
A high frequency vaginal probe with improved resolution offers a remarkable sharp clear image of pelvic organs. This is possible because of its closed proximity with target organ and non-intervention by gut or omentum. Study of ovarian follicular dynamics (folliculometry), identification of proliferative, secretory and decidual changes of endometrium (endometrial dating) in different phases of menstrual cycle and imaging of mucus secretion in the cervical canal (cervical mucus study) in the pre-ovulatory phase is possible by transvaginal probe. It is non-invasive, acceptable to patients, and thus can be repeated any number of times. A close serial monitoring offers immense wealth of information about the anatomical as well as reproductive endocrinal status of the patient. Ovulation can be predicted in advance. The case of dysovulation can be identified in first cycle of study; corrective therapy can be started in another two or three cycles, aiming at achieving perfect folliculogenesis. Once well tuned synchronised cycle is restored, the pregnancy outcome is remarkable. Thus transvaginal sonography offers one of the best reproductive endocrinology evaluation in the hand of a modern gynaecological sonologist and infertility specialist.
