[Formation of extraorganic ovarian nerves during the intrauterine period of human ontogeny].

By methods of histological investigation, plastic and graphic reconstruction, in 267 corpses of human embryos, prefetuses, fetuses and newborns, formation of extra- and intraorganic ovarian nerves has been studied. It has been stated that the neural fibres and trunklets grow into the ovarian anlage in prefetuses of 40-42 mm parietal-coccygeal length. The neural elements reach the ovarian anlage together with the ovarian artery and its branches. During the whole period of the intrauterine ontogenesis they concentrate in the mediastinum, albugineous membrane and in the ovarian interstitial connective tissue. As the gonads go down, the number of the extraorganic nerves increases, so does asymmetry in innervation of the right and left ovary. The number of the neural fibres and trunklets in the plexus around the left ovarian artery is greater than that of the right one.
