[Development of the obturator artery in human prenatal ontogenesis].
Definitive obturatory artery forms as a result of uneven growth of anastomosis of external and internal iliac arteries which is connected with peculiarities of regional organogenesis. 2 crucial periods--renal--and the period of gonade obstruction (the end of intrauterine development) were distinguished in morphogenesis of pubic anastomosis of iliac arteries. Sex related peculiarities of obturatory artery development were found in the second period.
