  • Title: Some aspects of development and homology of the genital glands arteries in cattle.
    Author: Wyrost P, Radek J, Radek T.
    Journal: Pol Arch Weter; 1989; 29(1-2):95-106. PubMed ID: 2486873.
    Abstract:
    The experimental studies have been carried out on 182 fetuses and 18 cattle neonates of both sexes. The pelvis blood vessels of the examined preparations have been filled with rubber latex using automatic device of our own design. On the basis of the detailed analysis of morphological and developmental features of genital glands i.e. ovarian artery and testicular artery, the rate and form of quantitative and qualitative transformations have been determined. It has been concluded that the primary form of the examined arteries, identical in sexually bipotential embryos, prefetuses and the youngest fetuses, has been undergoing transformations in older fetuses with the progressing sex determination. At the end of fetal life and in neonates, ovarian and testicular arteries take the form typical of sex and approximate to the species standard. Morphological features of these arteries, which should be considered as the ones of secondary sex character, have been identified as highly homologous.
