The origin of gonadal arteries in human fetuses: anatomical variations.
Testicular arterial anatomy has been well studied because of its importance in testicular physiology, as well as testicular and renal surgery. In contrast to classical anatomical descriptions, it may originate from the suprarenal or lumbar arteries or a high-positioned origin, course behind the inferior vena cava or be doubled or arise from an inferior polar renal artery. Different developmental patterns as variations in relation to origin, course and number of the renal and gonadal arteries have been reported and discussed. This study was performed on 90 spontaneously aborted fetuses obtained from two different hospitals in Konya. The study was carried out on the testicular or ovarian arteries of fetuses fixed by immersion in 10% formalin. In all, 180 gonadal arteries were studied and 16 of them were found to have variations in their origin (8.8%). The variations of the gonadal artery origins could be classified into four types. The gonadal artery variations were more commonly found in male than the female fetuses and on the right side rather than the left. In the present study, it is clear that these variations are important not only from the developmental point of view or research interest, but they also may explain some pathological conditions. Knowledge of these variations may help to avoid the clinical complications especially during radiological examinations and/or surgical approaches in this region.
