Nowadays, during formation and development of medicine, the main sector of health care is the protection of maternity and childhood. According to the Ministry of Health of Ukraine, inflammatory diseases of the reproductive system make up 60-65% of all gynecological diseases, among them inflammation of the fallopian tubes and ovaries is 79,6%, which occurs predominantly at young age. The aim is to study the microscopic structure of the oviducts wall in different anatomical parts during the embryonic period of human ontogenesis. Were studied uterine tubes of the 4-10 months' embryos. We used a light microscopy method and morphometry to describe the peculiarities of oviducts' infundibulum, isthmus and ampullary part in fetus from 81 mm to 375 mm PCL. The histotopography of the oviducts tunics and its parts (infundibulum, ampullary part, isthmus and uterine part) in the fetal period of ontogenesis is described in the article. The thickness of the oviduct wall in the dynamics of the fetal period increases in the direction from the infundibulum to the uterine part of the tube. The main part of the thickness of the oviduct wall is presented by muscles. The thickness of the circumferential muscle layer predominates over the thickness of the longitudinal in 2.5-2.8 times. Mucosa is thicker the isthmus, thinnest in the ampullary part of the uterine tube. The thickness of the infants oviduct wall in the dynamics increases in the direction from its infundibulum to the uterine part. The main part of the thickness of the oviduct wall is the tunica muscularis. The thickness of the circular muscle layer predominates the thickness of the longitudinal 2.5-2.8 times. Mucosa is thicker in the isthmus, the thinnest in the ampullary part. It is expedient to study the histotopography of the oviduct in the neonatal period of human ontogenesis.
